What has negative charge and positive charge with more exampal?

I'm not completely sure what your getting at with this question but here's my answer: In a sense, a neutron is both positively and negatively charged because when a neutron undergoes beta decay it releases both a positively charged proton and a negatively charged electron through an interaction involving a change in quarks via a weak force interaction.


What is difference between language constracter and function for exampal echo print in php language?

I think you mean language construct... Anyway, a function usually takes one or more arguments as comma separated values or variables. echo and print don't <?php $email = 'user@example.com'; $domain = strstr($email, '@'); echo $domain; // prints @example.com ?> Here the strstr function takes a variable string and a constant string as an argument. echo simply displays the contents of the resulting variable. There are a couple functions that don't require arguments, like die() & exit()

What is symmery list the three types of symmetry and give an exampal?

Symmetry1: balanced proportions2: close agreement in size, shape, and relative position of parts on opposite sides of a dividing line or plane or around a central pointThere are four types of symmetry:To rotate an object means to turn it around. Every rotation has a center and an angle. ---- To translate an object means to move it without rotating or reflecting it. Every translation has a direction and a distance. ---- To reflect an object means to produce its mirror image. Every reflection has a mirror line. A reflection of an "R" is a backwards "R". ---- A glide reflection combines a reflection with a translation along the direction of the mirror line. Glide reflections are the only type of symmetry that involve more than one step.HOPE I CAN HELP!


Give exampal of function continuous everywhere but not derivable any where?

I think the following piecewise function satisfies the two criteria: when x is rational: f(x)=x when x is irrational: f(x)=x*, where x* is the largest rational number smaller than x. I think not. When x is irrational, there is no largest rational number less than x. No matter what rational number you pick, there is a larger one that is less than x. For example, between 3.1415926 and pi, there is 3.14159265. The usual answer is the one given by Weierstrass, which is the sum of an infinite series of functions. The first term in the series is a periodic sawtooth (piecewise linear) function, which is = x from x=0 to x=1, and then descends back to 0 between x=1 and x=2 (i.e., it is = -x+2 in that interval). It repeats that pattern between x=2 and x=4, and so on. The second term is just like it, but with 1/10 the frequency and 1/10 the amplitude, and so on. The first function is continuous everywhere and differentiable except at x= an integer. The sum of the first 2 is continuous everywhere and differentiable except for the multiples of 1/10, and so on. It turns out that the series converges to a function that is continuous everywhere and differentiable nowhere. By the way, if you can take the derivative of a function at a given point, it is said to be differentiable, not derivable at that point.


How can you tell if someone doesn't like you as a person?

People can be very cruel. You can have individuals that actually voice their feelings or opinions of you directly to your face, individuals may be short with you or try to avoid you, and there are others that are overly nice and obviously phoney towards you.


What are reallife applications of graphs in data structures?

Applications of graph theory are primarily, but not exclusively, concerned with labeled graphs and various specializations of these. Structures that can be represented as graphs are ubiquitous, and many problems of practical interest can be represented by graphs. The link structure of a website could be represented by a directed graph: the vertices are the web pages available at the website and a directed edge from page A to page B exists if and only if A contains a link to B. A similar approach can be taken to problems in travel, biology, computer chip design, and many other fields. The development of algorithms to handle graphs is therefore of major interest in computer science. There, the transformation of graphs is often formalized and represented by graph rewrite systems. They are either directly used or properties of the rewrite systems(e.g. confluence) are studied. A graph structure can be extended by assigning a weight to each edge of the graph. Graphs with weights, or weighted graphs, are used to represent structures in which pairwise connections have some numerical values. For example if a graph represents a road network, the weights could represent the length of each road. A digraph with weighted edges in the context of graph theory is called a network. Networks have many uses in the practical side of graph theory, network analysis (for example, to model and analyze traffic networks). Within network analysis, the definition of the term "network" varies, and may often refer to a simple graph. Many applications of graph theory exist in the form of network analysis. These split broadly into three categories. Firstly, analysis to determine structural properties of a network, such as the distribution of vertex degrees and the diameter of the graph. A vast number of graph measures exist, and the production of useful ones for various domains remains an active area of research. Secondly, analysis to find a measurable quantity within the network, for example, for a transportation network, the level of vehicular flow within any portion of it. Thirdly, analysis of dynamical properties of networks. Graph theory is also used to study molecules in chemistry and physics. In condensed matter physics, the three dimensional structure of complicated simulated atomic structures can be studied quantitatively by gathering statistics on graph-theoretic properties related to the topology of the atoms. For example, Franzblau's shortest-path (SP) rings. In chemistry a graph makes a natural model for a molecule, where vertices represent atoms and edges bonds. This approach is especially used in computer processing of molecular structures, ranging from chemical editors to database searching. Graph theory is also widely used in sociology as a way, for example, to measure actors' prestige or to explore diffusion mechanisms, notably through the use of social network analysis software. Likewise, graph theory is useful in biology and conservation efforts where a vertex can represent regions where certain species exist (or habitats) and the edges represent migration paths, or movement between the regions. This information is important when looking at breeding patterns or tracking the spread of disease, parasites or how changes to the movement can affect other species.


How do you recruit Groudon in blue rescue team?

First, your character must be atleast Level 40.(make sure you fought Rayquaza and saved the world before you do this) Your team needs to be on Diamond Rank or higher. Then, go to Magma Cavern. Make sure you bring the following items: Friend Bow(optional) Reviver Seeds Apples or Huge Apples Gravelrocks, Iron Thorns, Sticks, or Silver Spikes(if you dont have any moves like Quickattack or Hydropump) Go all the way until you reach Groudon. Before making a move, make your Friend Bow your hold item. Then, use your weapons or your moves that can be used away from opponents, and when Groudon walks in front of you, start using moves on him. Use super-effective moves(if you have any) and use the weapons too. If you have moves like Attract or Stun Spore, use' em, and stop Groudon from moving. Defeat him with all your might, and if lucky, he will ask to join your team.(You may have to encounter him a few more times if he goes away) Good luck!!


Explain each stage in the life cycle of a fern?

Life Cycle of a FernFerns, unlike some other plants, do not flower in order to propagate. Instead, they reproduce sexually from spores. The life cycle of a fern is very different from the life cycle of many other plants. While many plants grow a mature adult form straight out of the seed, ferns have an intermediate stage, called a gametophyte, which then grows into a mature fern.There are two distinct stages in the life cycle of ferns. The first stage is that of the gametophyte. Spores are produced on the underside of mature plants. These will germinate and grow into small, heart-shaped plants called gametophytes. The gametophytes produce both sperm and egg cells, and will fertilize itself, or others. Once the fertilization occurs, the adult fern will begin growing.The second stage in the life cycle of a fern is the adult stage. The fertilized gametophytes begin to look like a mossy growth. After some time, young fronds will appear, rising out of the moss. If direct sunlight falls onto the young fronds for an extended period of time, the plant may die easily. This is because the tiny stems are not strong enough to sustain direct light and will dry out.Buy Ferns from ourrecommended sourceClick hereOnce these tiny fronds grow larger, the plant has a better chance of survival. When the veins are matured, moisture from the ground will be transported easily to the outermost leaves and the plant can withstand periods of direct sunlight. After the plant is large and mature, it will grow spores on the undersides of its leaves and the life cycle of a fern will begin again.A fern is any one of a group of about 12,000 species of plants belonging to the botanical group known as Pteridophyta.[3] Unlikemosses, they have xylem and phloem (making them vascular plants). They have stems, leaves, and roots like other vascular plants. Ferns reproduce via spores and have neither seeds nor flowers.By far the largest group of ferns is the leptosporangiate ferns, but ferns as defined here (also called monilophytes) include horsetails,whisk ferns, marattioid ferns, and ophioglossoid ferns. The term pteridophyte also refers to ferns and a few other seedless vascular plants (see classification section below).Ferns first appear in the fossil record 360 million years ago in the Carboniferous but many of the current families and species did not appear until roughly 145 million years ago in the early Cretaceous (after flowering plants came to dominate many environments).Ferns are not of major economic importance, but some are grown or gathered for food, as ornamental plants, for remediating contaminated soils, and have been the subject of research for their ability to remove some chemical pollutants from the air. Some are significant weeds. They also play a role in mythology, medicine, and art.Ferns are vascular plants differing from lycophytes by having true leaves (megaphylls), which are often pinnate. They differ from seed plants(gymnosperms and angiosperms) in their mode of reproduction-lacking flowers and seeds. Like all other vascular plants, they have a life cycle referred to as alternation of generations, characterized by alternating diploid sporophytic and haploid gametophytic phases. The diploid sporophyte has 2npaired chromosomes, where n varies from species to species. The haploid gametophyte has n unpaired chromosomes, i.e. half the number of the sporophyte. Unlike the gymnosperms and angiosperms, the ferns' gametophyte is a free-living organism.Life cycle of a typical fern:A diploid sporophyte phase produces haploid spores by meiosis (a process of cell division which reduces the number of chromosomes by a half).A spore grows into a haploid gametophyte by mitosis (a process of cell division which maintains the number of chromosomes). The gametophyte typically consists of a photosynthetic prothallus.The gametophyte produces gametes (often both sperm and eggs on the same prothallus) by mitosis.A mobile, flagellate sperm fertilizes an egg that remains attached to the prothallus.The fertilized egg is now a diploid zygote and grows by mitosis into a diploid sporophyte (the typical "fern" plant).The stereotypic image of ferns growing in moist shady woodland nooks is far from being a complete picture of the habitats where ferns can be found growing. Fern species live in a wide variety of habitats, from remote mountain elevations, to dry desert rock faces, to bodies of water or in open fields. Ferns in general may be thought of as largely being specialists in marginal habitats, often succeeding in places where various environmental factors limit the success of flowering plants. Some ferns are among the world's most serious weed species, including the bracken fern growing in the Scottish highlands, or the mosquito fern (Azolla) growing in tropical lakes, both species forming large aggressively spreading colonies. There are four particular types of habitats that ferns are found in: moist, shady forests; crevices in rock faces, especially when sheltered from the full sun; acid wetlands including bogs and swamps; and tropical trees, where many species are epiphytes (something like a quarter to a third of all fern species[4]). Many ferns depend on associations with mycorrhizal fungi. Many ferns only grow within specific pH ranges; for instance, the climbing fern (Lygodium) of eastern North America will only grow in moist, intensely acid soils, while the bulblet bladder fern (Cystopteris bulbifera), with an overlapping range, is only found on limestone.The spores are rich in lipids, protein and calories, so some vertebrates eat these. The European woodmouse (Apodemus sylvaticus) has been found to eat the spores of Culcita macrocarpa and the bullfinch (Pyrrhula murina) and the New Zealand lesser short-tailed bat (Mystacina tuberculata) also eat fern spores.Ferns first appear in the fossil record in the early-Carboniferous period. By the Triassic, the first evidence of ferns related to several modern families appeared. The "great fern radiation" occurred in the late-Cretaceous, when many modern families of ferns first appeared.One problem with fern classification is the problem of cryptic species. A cryptic species is a species that is morphologically similar to another species, but differs genetically in ways that prevent fertile interbreeding. A good example of this is the currently designated species Asplenium trichomanes, the maidenhair spleenwort. This is actually a species complex that includes distinct diploid and tetraploid races. There are minor but unclear morphological differences between the two groups, which prefer distinctly differing habitats. In many cases such as this, the species complexes have been separated into separate species, thus raising the number of overall fern species. Possibly many more cryptic species are yet to be discovered and designated.Ferns have traditionally been grouped in the Class Filices, but modern classifications assign them their own phylum or division in the plant kingdom, called Pteridophyta, also known as Filicophyta. The group is also referred to as Polypodiophyta, (or Polypodiopsida when treated as a subdivision of tracheophyta (vascular plants), although Polypodiopsida sometimes refers to only the leptosporangiate ferns). The term "pteridophyte" has traditionally been used to describe all seedless vascular plants, making it synonymous with "ferns and fern allies". This can be confusing since members of the fern phylum Pteridophyta are also sometimes referred to as pteridophytes.Traditionally, three discrete groups of plants have been considered ferns: two groups of eusporangiate ferns-families Ophioglossaceae (adders-tongues, moonworts, and grape-ferns) and Marattiaceae-and the leptosporangiate ferns. The Marattiaceae are a primitive group of tropical ferns with a large, fleshy rhizome, and are now thought to be a sibling taxon to the main group of ferns, the leptosporangiate ferns. Several other groups of plants were considered "fern allies": the clubmosses, spikemosses, and quillworts in theLycopodiophyta, the whisk ferns in Psilotaceae, and the horsetails in the Equisetaceae. More recent genetic studies have shown that the Lycopodiophyta are more distantly related to other vascular plants, having radiated evolutionarily at the base of the vascular plant clade, while both the whisk ferns and horsetails are as much "true" ferns as are the Ophioglossoids and Marattiaceae. In fact, the whisk ferns and Ophioglossoids are demonstrably a clade, and the horsetails and Marattiaceae are arguably another clade. Molecular data-which remain poorly constrained for many parts of the plants' phylogeny - have been supplemented by recent morphological observations supporting the inclusion ofEquisetaceae within the ferns, notably relating to the construction of their sperm, and peculiarities of their roots.[2] However, there are still differences of opinion about the placement of the Equisetum species (see Equisetopsida for further discussion). One possible means of treating this situation is to consider only the leptosporangiate ferns as "true" ferns, while considering the other three groups as "fern allies". In practice, numerous classification schemes have been proposed for ferns and fern allies, and there has been little consensus among them.A 2006 classification by Smith et al. is based on recent molecular systematic studies, in addition to morphological data. Their phylogeny is a consensus of a number of studies, and is shown below (to the level of orders).[2][6]Trachaeophytalycophytes (club mosses, spike mosses, quillworts)euphyllophytesspermatophytes (seed plants)fernsPsilotopsidaPsilotales (whisk ferns)Ophioglossales (grapeferns etc.)EquisetopsidaEquisetales (horsetails)MarattiopsidaMarattialesPolypodiopsidaOsmundalesHymenophyllales (filmy ferns)GleichenialesSchizaealesSalviniales (heterosporous)Cyatheales (tree ferns)Polypodialeseusporangiatefernsleptosporangiateferns
