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 fatty acids in the tail of a phospholipid molecule are non-polar and hydrophobic.
Fats that you take in from your food is used to build membranes. Membranes can be represented by models such as The Fluid Mosaic Model, which displays the phospholipid bilayr, and other tissues on the membrane.
Answer:disease preadertism and preadation
Explanation:
because of the sciency stuff
Like D. Codon is the answer
The correct answer to this question is letter B.its ability to form endospores in harsh conditions
The bacterium Bacillus anthracis, which causes anthrax, has been developed as a biological warfare agent. The ability that could have led to this is that its ability to form endospores in harsh conditions
Anthrax usually form endospores in non-bacteria friendly environments, meaning they could get into places that would otherwise be hygienic and infect individuals.
