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).

<span>Answer: T-cells are made to identify antigens, while inflammation fights anything in the affected area
</span>
The adaptive immune cells are made of B-cell and T-cell. The function of B-cells is to produce antibodies, while T-cells will detect antigens of the pathogen. If T-cells detect an antigen from a cell, it will assume that the cells are infected. It will send a signal to the infected cells which tell them to do apoptosis. Inflammation is not specific, which makes them not strong.
The correct option is LIZARD AND FROG.
Predator refers to an animal which uses another animal as food. In the question given above, we are told that the insect is consumed by the frog and the lizard. This means that the frog and the lizard are the predators of insects.
This is comparable to the impression of the 'sneaky' males
in the side-blotched lizard. Natural section favor an individual by the detector
or sensor will sustain less cost and increase an advantage and gain over others
incapable to distinguish the deceitfulness.
