Renewable energy is exactly what it says -- it's renewable. Meaning, you can continue to reuse it or make more of it in a never ending cycles. Examples of a renewable energy could be trees (wood). You can keep growing trees and harvesting them.
Fossil fuels are things like oil or petroleum, they cannot be "grown" again, and are a one-time use.
Renewable energy has more benefits then that of fossil fuels because you can reuse renewable energy and keep the never-ending circle of energy going, unlike fossil fuels which can run out.
The four principles of natural selection are variability among members of a species, heritability of the variable features, differences in population members' ability to reproduce and survival of the fittest in terms of variability, heritability and reproduction. Natural selection is one of evolution's four mechanisms.
Natural selection acknowledges the fact that members of a population are capable of producing more offspring than are needed to maintain a healthy population size. Nature controls the population's size by empowering species' best specimens to survive and reproduce.
Variability among population members refers to differences in such traits as eye color or hair color, and it serves as natural selection's foundation. The variable traits must be heritable, which means they are passed down from one generation to the next. Differences among population members' ability to reproduce refers to the fact that some population members are able to reproduce and some are not. These three factors combine to help ensure the survival of the fittest, which means that the population members with the most desirable traits reproduce and create new members that share those traits, whereas members with undesirable traits fall into obscurity.
Answer:
a) Anabolic pathways
Explanation:
The metabolic pathways that form complex biomolecules from simpler elements are called anabolic pathways. Anabolic pathways are mostly endergonic, that is, they require an input of energy.
For example, the synthesis of glucose (C6H12O6) from simpler CO2 and H2O in the presence of sunlight during photosynthesis. Here, complex glucose molecules are formed from simpler elements such as carbon dioxide and water. Sunlight serves as a source of energy for photosynthesis.
