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).

D is the correct answer. (Panting in a dogs increases the amount of cool air in nasal passages and lowers body temp).
Answer:COmpound names. Sorry I couldnt help with all. good luck!
Explanation:
LiF-Lithium flouride
BeO-BerylliumOxide
CaCl_2-Calcium Chloride
AlF_2-Difluoroaluminum
CaO-Oxacalcium
MgS-Magnesium sulfate
K_2O-Potassium Oxide
BaCl_2- Barium Chlroide
The plant is classified as a Monocot.
Monocotyledons have only one cotyledon in the embryo. Its leaf veins are parallel. Its petals are in the multiples of three. It has a fibrous root pattern. It does not have a secondary growth. It does not have a cortex and its stem and vascular system is composed of bundles of vascular tissue scattered all throughout the stem without any specific arrangement.

-The nervous system coordinates the systems of the body.
-The nervous system sends out appropriate responses to react to changes in the environment.
-The nervous system maintains homeostasis.</span>
