Most Archaeans lack a ______ cell wall.

Biology
1 answer:
Morgarella [4.7K]4 years ago
6 0
Most Archaens lack peptidoglycan<em> </em>a.k.a murein in their cell wall. Peptidoglycans help maintain the strength of the cell wall as well as repel the osmotic pressure in the cytoplasm. A common misconception of the use of peptidoglycans is that it gives the cell shape. However, peptidoglycans only improve the structure of the cell wall by strengthening it.

What is cell surface to volume ratio and why is it important in cell functioning? Can it explain why cells are so small?
MrMuchimi
<span>The main reason surface area to volume ratio is important to a cell is because the surface area to volume ratio determines the rate at which cells uptake nutrients, liquids or gases. For instance, I have two organisms, A and B. Organism A has a surface area to volume ratio of 6:1, whereas organism B has a surface area to volume ratio of 3:1. As organism A has a greater surface area to volume ratio, it means that organism A will be able to take up nutrients, liquids or gases via diffusion or osmosis at a greater rate than organism B, as it has more surface with which to exchange nutrients, liquids or gases. </span>

Classify the structures as homologous or analogous , depending on their structure and function
Vesnalui [34]

1) The limbs of a bat and the forelimbs of a bird is an example of Analogous structures

2) The arm of a human and the arm of chimpazee is an example of Homologous structures 

3) Frogs and salamanders is an example of Homologous structures

<span>Homologous structures, are organs or systems of different living beings that have a common origin, but different adaptations. For example, the extremities of a dog and a dolphin, are homologous, have similar bones, only that some adapted to the race and others to swimming. On the other hand, analogous structures are organs or systems of different living beings that do not have a close origin in common, but are adapted to the same environment, for example, fins of fish and dolphin fins, the function is the same, the origin is different; or the wings of birds and the wings of insects.</span>
