Answer:
Explanation:
The fossil record
This supports Darwin's theory of evolution, which states that simple life forms gradually evolved into more complex ones. Evidence for early forms of life comes from fossils. By studying fossils, scientists can learn how much (or how little) organisms have changed as life developed on Earth.
Answer:
An electrochemical Gradient
Explanation:
During the translation of mRNA to protein, the nascent polypeptide chain that is formed is not yet a functional protein right after translation. The polypeptide must then undergo another series of processing and packaging and may even need another protein(s) to completely form a functional moiety. Generally, for this a mix of chaperones may be needed to complete the protein synthesis pathway.
Since it’s natural environment is very acidic, putting pepsin in a very alkaline environment would cause it to denature.
3. any trait that confers even a small increase in the probability that its possessor will survive and reproduce will be strongly favored and will spread through the population.
Explanation:
- Natural selection is a nonrandom process by which biological traits become more or less common in a population as a function of the differential reproduction of their bearers of differences in the rate of survival.
- Natural selection can act on any heritable phenotypic trait and operate among any entities that reproduce, show inheritance of their characteristics from one generation to the next, and vary in fitness.
- Natural selection is the machine that drives evolution. It also explains adaptation.
