What is a possible explanation for why bacteria lack ether-linked cell membranes

Biology
1 answer:
oee [108]3 years ago
3 0

Answer:

Because they do not live in the extreme environments.

Explanation:

Cell membrane has a vital role in separating the external environment of cell from its external environment. Just like eukaryotic cell, cell membrane of bacteria is also composed of proteins and lipids (phospholipids).

If we compare the structure of ancient bacteria's and modern bacteria's cell membrane then we notice that in  archaebacteria or ancient bacteria the phospholipids of cell membrane are linked with ether (means they have glycerol backbones). whereas in modern bacteria they are linked through ester linkages.

So, the stronger glycerol backbones give the archaebacteria more stable cell membranes through which they are able to resist harsh environmental stresses like salt lakes, volcanic stress, boiling mud and hot springs. As modern bacteria do not always have to live under such stresses thats why they donot have ether-linked cell membrane.

Hope it helps!

Why would rapid change in climate potentially lead to ecological problems?
nadya68 [22]

The rapid change in the climate would potentially lead to ecological problems because evolution is unlikely to occur quickly enough to keep pace with biome changes.

<h3>What do you mean by Evolution?</h3>

Evolution may be defined as the process of growth and development or the theory that organisms have evolved and developed from past organisms.

Biome changes occur due to the fact of evolution. Both evolution and biome changes synergistically move forward to support organisms' life in a much better way.

Therefore, the rapid change in the climate would potentially lead to ecological problems because evolution is unlikely to occur quickly enough to keep pace with biome changes.

How does the release of energy and nutrients from digestion help the rest of the body's systems?
olasank [31]

Answer:

Explanation:

The main goal of metabolism is for the ultimate release of energy. Energy is simply a function of the ability to do work. In this context, we consider energy in one of it forms, chemical energy.

The chemical energy obtained through digestion of food mostly in the form of glucose is the fuel for almost all of life's processes. This chemical form of energy serves as the power house for our functioning.

Energy is required by the brain to power it and carry out its function. Without energy being supplied to the brain, there won't be a living being.

Energy is needed for locomotion and other life activities. The muscles, bones and other appendages gets their coordination power from the energy released during metabolic processes.

It can be said that all life activities revolves round how organisms obtains and utilize energy.

Nutrients are the nourishment we derive from feeding. The nutrients helps to build our body parts e.g proteins. Energy are derieved from carbohydrates. Fats and oil are also energy sources and they help life functions. Vitamins and minerals supplies needed materials to make everyday life activities successful.
