Answer:
The correct answer is C. co-evolution
Explanation:
When two or more species evolution is influenced by each other and are interdependent than this type of evolution is known as co-evolution. There are several examples of co-evolution like predator-prey co-evolution, flowering plants and pollinators evolution, etc.
The predator-prey evolution is famous in which there is selective pressure on prey to evolve to avoid getting hunted and the same pressure is on predator to evolve with prey so that they can get their food and survive. Therefore the correct answer is co-evolution.
The answer is The Doppler Effect. It is named after the Austrian physicist Christian Doppler, who described the phenomenon in 1842.

The question has incorrect option, however the question can be answered by the general explanation. On the basis of the general explanation the answer is as follows:
Answer:
The correct answer is - Serine has a small side chain that can fit in any relatively polar environment.
Explanation:
Serine is an amino acid that have a small side chain in comparison of other amino acid and can be replaced by another amino acid with very least effect on the structure and function of a particular protein as they can fit in any relatively polar environment.
Serine have hydroxyl group in their side chain. It is polar amino acid that can easily establish itself in any polar condition and cause least changes in protein structure and function.
Thus, the correct answer is - Serine has a small side chain that can fit in any relatively polar environment.
Answer:
The correct statement concerning the cell membrane lipid molecules is that "energy is not expended during diffusion" (Option d)
Explanation:
Biological membranes are formed by two lipidic layers arranged with their hydrophilic polar heads facing the exterior and the interior of the cells, and their hydrophobic tails against each other. Membranes are fluid, which means that molecules that form it have the capability to move through it.
Lipids can easily change places with other neighbor lipids by <u>lateral diffusion</u> in the same layer. This is passive diffusion, which means that it does not need energy to happen.
Lipids can also diffuse transversally to the other layer, but this kind of movement is not as easy as lateral diffusion.
There are also other lipidic movements as rotational diffusion that imply the rotation of the molecule.
Through this lipidic bilayer, there is also a passive transport of some particles from one side of the cell to the other which happens because of concentration differences.
