PLEASE HELP. I REALLY NEED THIS!!!!
Viefleur [7K]

Answer:

In nature, populations are usually evolving. The grass in an open meadow, the wolves in a forest, and even the bacteria in a person's body are all natural populations. And all of these populations are likely to be evolving for at least some of their genes. Evolution is happening right here, right now!

To be clear, that doesn't mean these populations are marching towards some final state of perfection. All evolution means is that a population is changing in its genetic makeup over generations. And the changes may be subtle—for instance, in a wolf population, there might be a shift in the frequency of a gene variant for black rather than gray fur. Sometimes, this type of change is due to natural selection. Other times, it comes from migration of new organisms into the population, or from random events—the evolutionary "luck of the draw."

I hope this helps a little bit.

Vilka [71]

If we say something is beneficial, it must be positive and really mean to give advantage to one thing or another. Wave energy is a renewable energy since it can be used repeatedly over time without any problem on supply. Hence the greatest benefit it can give would be:

Answer:

Answer is Option C.

The concentration of organic molecules by the process of dehydration synthesis can facilitate their assembly into macro molecules.

Explanation:

Macromolecules are large molecules formed by covalent bonds between monomers. They are a growing chain of monomers assemble through a process called dehydration synthesis in which one monomer forms a covalent bond with another monomer by releasing a water molecule. This is a process that requires energy. For example, two glucose molecules (monomers) combine to form a single maltose molecule. As a new covalent bond forms between the two glucose molecules, a water molecule is released.

Evaporation is a process in which water vapor is formed from water. The tendency of dissimilar particles to stick together is known as adhesion.
