Why 70 percent ethyl alcohol is used rather than 90 percent or 95 percent?
70% alcohol has been found to be more effective in killing microbes.Higher and lower concentration may not be as effective.90% alcohol coagulate proteins in contact.suppose 90% alcohol is poured over one celled organism,the alcohol penetrate the cellwall of the organism.the coagulated protein would then prevent the alcohol further from the cell and no more coagulation then take place.now,if 70% alcohol is added into one celled organism.The diluted alcohol also coagulates the protein, but at a slower rate,so that it penetrates all the cell before coagulation.Then all the cell coagulated and the organism died.
Is the surface-area-to-volume ratio of a small cell less than that of a larger cell?
As a cell becomes larger the surface area to volume ratio gets smaller. The volume increases by the square of the surface area. That is the main reason that one celled organisms are small.
Can you see into the second dimension?
As you know, 3d stands for 3 dimensional. We see in 3d everyday. We can also move in 3d. We call it 3 dimensional because we can move (up and down, left to right, and forward and backwards). If you eliminate one of these sets of movements then you eliminate a dimension and you are now in 2d. We an see in the 2nd dimension and 1st dimension because we are at 3d. But we cannot see a 4d (if there is one. there are theories that there are an infinite number of dimensions) because we are not able to move with in the boundaries of 4d.
What are 7 different kinds of algae?
Diatoms - Unicellular orgasnisms of the protista kingdom.Chlorophyta - A division of the kingdom of protista (known as green algae).Euglenophyta - Small phylum of the protista kingdom (mostly unicellular).Dinoflagellata - A large group of protists, many of these organisms contain chlorophyll.Chrysophyta - Eukaryotic algae (known as goldenalgae).Phaeophyta - Belonging to the protista kingdom (known as brown algae).Rhodophyta - Belonging to the protista kingdom (known as red algae).
What is difference between a cingle-celled organism and a multi-celled organism?
a singe celled is a prokaryote and multi celled is a eukaryote
Do monerans have backbones?
No, monerans do not have backbones. Monerans are single-celled organisms without complex structural features like backbones.
What is the difference between monerans and protists?
Monerans are a group of single-celled organisms that lack a distinct nucleus, while protists are a diverse group of eukaryotic organisms that can be single-celled or multicellular. Monerans include bacteria and archaea, while protists include organisms like algae, amoebas, and ciliates.
Do monerans have on cell or many cells?
Monerans typically consist of a single cell and are considered unicellular organisms. They lack a true nucleus and other membrane-bound organelles found in more complex organisms.
Exaim the difference between an organism and a species?
An organism is a single-celled life form whereas a species refers to a group of organisms.
What are the differences between archaebacteria and monerans?
Archaebacteria and monerans are both classifications of single-celled organisms, but monerans belong to the domain Bacteria while archaebacteria belong to the domain Archaea. Archaebacteria are known for living in extreme environments, while monerans are more commonly found in diverse habitats. Additionally, archaebacteria have unique cell membrane structures and genetic sequences that distinguish them from monerans.
What are facts about monerans?
Monerans are a type of prokaryotic organism, which means they lack a distinct cell nucleus. They are single-celled microorganisms that can be found in a variety of environments, including soil, water, and even in extreme conditions like hot springs. Monerans reproduce asexually through methods like binary fission.
Are monerans multicellular?
No, monerans are unicellular organisms. They are prokaryotes that do not have a true nucleus or membrane-bound organelles.
What is the difference between a microorganism and unicellular organism?
A microorganism is a tiny organism that can be single-celled or multi-celled, while a unicellular organism is an organism that is composed of only one cell. Therefore, all unicellular organisms are microorganisms, but not all microorganisms are unicellular.
What is the difference between a unicellular organism and a single cell organism?
Cell is the structural and functional unit of life while ,unicellular organism refers to an organism. Cell is present in both unicellular and multicellular organisms where as , unicellular organisms are composed of only one cell.
Which kingdom contain one celled living things without nuclei?
Monerans.
In what ways if any does a single-celled organism differ from its parent?
A single-celled organism is typically the result of asexual reproduction, where the parent cell divides into two identical daughter cells. Therefore, the main difference between a single-celled organism and its parent would be that the parent cell has divided to create a new individual.
