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.
What are the two Example of Spirozoa?
Two examples of Spirozoa are Euglena and Trypanosoma. Euglena is a single-celled organism known for its flagella and ability to photosynthesize, while Trypanosoma is a parasitic protozoan responsible for diseases such as African sleeping sickness. Both organisms exhibit unique adaptations that allow them to thrive in their respective environments.
How does the length of the man compare to the length to the paramecium?
The length of a typical adult human male averages around 1.7 meters (5.6 feet), while a paramecium is only about 0.05 to 0.25 millimeters in length. This means that a human is approximately 6,800 to 34,000 times longer than a paramecium. The significant size difference highlights the vast disparity between multicellular organisms, like humans, and single-celled organisms, such as paramecia.
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.
What is the function of the dinoflagellate?
Dinoflagellates are a diverse group of single-celled organisms that play crucial roles in marine ecosystems. They are significant primary producers, contributing to the base of the food web through photosynthesis, and some species can also cause harmful algal blooms, impacting marine life and human activities. Additionally, dinoflagellates are involved in nutrient cycling and can exhibit bioluminescence, adding to their ecological importance. Their unique characteristics and adaptability make them vital for oceanic health and productivity.
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?
The Moneran is part of the unicellular organism kingdom and is a single cellular organism. As it has no nuclear membrane it has a prokaryotic cell organization like bacteria.
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.
