In a range with heterogeneous distribution of suitable habitats the dispersion pattern of a population would probably be?
clumped
What does Population distribution describe?
Population Distribution is the measure of people in a certain area. To be specific it looks at if the people living in a certain area are all clumped together or if they are evenly spread apart. In most cases, people are clumped together because they are attracted to the features of the land. For example, many people live in Toronto due to it being on the water, having a favourable land surface, very industrialized city, stable government, multicultural etc.
A score set has a mean of 53 and a standard deviation of 5.6 If each score was multiplied by 0.9 and then had 7 added state the new standard deviation?
Standard deviation is the spread of the data. If each score has 7 added, this would not affect the spread of the data - it would be just as evenly spaced or clumped up, but 7 greater. The only thing that would affect the spread is multiplying every data point by 0.9. This makes distances between the data points 0.9 times as big, and thus makes the standard deviation 0.9 times as big. The standard deviation was 5.6, and so now is 5.6x0.9 = 5.04
Why is sounds fainter further away?
As the sound wave travels out from the source, the same amount of energy is covering a bigger and bigger area, so there is less energy per square inch. (In particular, less energy in the square inch reaching your eardrum.) Imagine the energy as a lump of clay. When a sound wave is only 6 inches (15cm) from the source, the clay has to cover the *surface* of a radius 6in ball, and the clay can be clumped on pretty thick. But as the sound travels outward to 60in (= 5ft =~ 150cm), that same amount of clay now has to cover the surface of the much bigger ball, so it will have to be very thin. Geometry tells us that the surface area of a sphere is proportional to the radius *squared*. This means that as you get twice as far away from a sound, only a *quarter* of the original energy reaches you. If you get ten times further away (like in the example above), then only a *hundredth* of the original energy reaches you. [The human ear/brain is sensitive though; half the energy doesn't necessarily mean the brain interprets it as half as loud; the ear/brain has more of a logarithmic response: half the energy is like turning the volume knob down one notch; a sixteenth of the energy is like turning it down four notches. Decibels are units that measure the *logarithm* of the energy, which is why they are suitable units for talking about human hearing.]
What is the game marbles?
Marbles is a game that uses marbles along with a circle. The goal is to knock your opponents marbles out of a created circle by flicking your marbles towards theirs. Whoever has all of their marbles outside the circle first loses. ********************** Actually, there are many, many variations of the game. Some are only played in certain countries or regions of countries and not all involve knocking out another marble. A popular marble game in France has you flicking your marble around a track like it was a race. In part of Tennessee/Kentucky area they play Roley Hole which has teams of 2 shooting their marble back and forth in their playing Field going into 3 different holes. Very complex and lots of strategy with that one. There is an old game called potsie where you shot your marble into a single hole. These versions don't use any target marbles - only a shooter. Then there are many versions that do use a target marble. In the US, the National Marbles Tournament plays ringer and the US Marbles Championship plays a modified version of ringer but both involve knocking target marbles out of a ten foot diameter circle. In England, during the British and World Marbles Championship, 49 target marbles are clumped together on a six foot diameter, 4 inch raised ring lightly covered in sand.
What type of population distribution do such fish have?
Clumped
In a range with heterogeneous distribution of suitable habitats the dispersion pattern of a population would probably be?
clumped
What type of population distribution do fish have?
clumped
The image below shows the distribution of members of a population. What type of distribution is shown?
Clumped
What are the 3 dispersion patterns in an ecosystem?
randomly spaced, evenly spaced, and clumped distribution.
What is an example of clumped distribution pattern?
It it probaly an organism of a sort
Give an example of a social behavior that can produce a clumped distribution?
Clumped populations are usually a product of desire for protection or varying resources. Fish swim in schools because it is less likely for any one fish to be consumed, while a species of plants may gather around an area of increased nutrients.
What type of population distribution do school fish have?
The type of population distribution that schools of fish have is clumped/clustered.
What is the definition of a cline and a cluster?
A cluster is a clumped distribution while cline represents a continuous distribution (a gradient).
What marine community distribution is the most common one found in nature?
clumped
A school of fish in the ocean is best described as what type of population distribution?
Clumped
Are clumped distributions the most common type of distribution in nature?
Yes, it is the most common distribution of a species in nature for the sake of survival and adaptation.
