when changes in a protein appear to accumulate at a constant rate over time is called option (c) i.e, Molecular clock.
<h3>What does molecular clock mean?</h3>
The term "molecular clock" refers to a method that estimates the time in prehistory when two or more life forms diverged by analyzing the mutation rate of biomolecules. Typically, nucleotide sequences for DNA, RNA, or amino acid sequences for proteins serve as the biomolecular data for these calculations.
Hedges, a biology professor at Penn State, claims that the molecular clock counts the mutations that accumulate through time in the gene sequences of various species rather than counting seconds, minutes, and hours.
Mutation and recombination, the two fundamental biological processes that give rise to all heritable variations, are the foundation of molecular clocks. Mutations are modifications to the genetic code of DNA, for as when the nucleotide Guanine (G) turns to Thymine (T).

The answer is B hope this helps
Answer:
Well I was gonna say B
Explanation:
I didnt understand ur question if u thought it was D or if that was a smile face why u would smile but I'm going to say B because the bars on the grill are touching the food and transfering heat
You didn't provide us with any possible ways? Primary reinforcers are, however, types of reinforcers where they immediately elicit a reward or reward-like behavior once they are applied in a situation. An example would be apple juice.
Secondary reinforcers on the other hand need to be associated with something for them to become reinforcers or they provide rewards in a non-direct way. An example would be money.
This is the main relationship between them.
The earth's atmosphere consists mainly of nitrogen and oxygen with smaller proportions of other gases such as carbon dioxide. The amount of carbon dioxide in the atmosphere is maintained through a balance between processes such as photosynthesis, respiration and combustion. However this balance is being affected by human activities which are polluting the atmosphere.
The proportion of these gases in the atmosphere is as follows: nitrogen is the most abundant at 78%, oxygen is next at 21%, while others include carbon dioxide at 0.037% and argon at 0.9 % .
