I'd say it's (A)/ Calcitonin since it actually decreases blood calcium levels by inhibiting stimulating osteoblasts, osteoclasts, and stimulating calcium excertion by the kidneys. I hope this response will help you.
They are measuring the time that two species have been evolving independently.
A molecular clock is a method that is used by scientists to estimate the time that two species evolve separately using the knowledge of the DNA differences. To carry out this method, scientists use (i) an estimate of the number of genetic mutations that occur between two closely related species and (ii) the average genetic mutation rate to estimate the time in prehistory when the two species split.
b. evolution.
c. variation.
d. adaptation.
In a biological context, 'change over time' refers to evolution. Evolution is a process by which living organisms have developed and diversified from earlier forms over time. Mutation, variation, and adaptation are components of this process.
The term 'change over time' in biology usually refers to the concept of evolution. Evolution can be defined as the process by which different kinds of living organisms have developed and diversified from earlier forms during the history of earth. This involves slow changes happening in species over long periods. This could be due to factors like genetic variation, environmental changes, and natural selection.
On the other hand, mutation, variation, and adaptation are components of evolution. A mutation is a change within the DNA of a gene. A variation represents the differences within a species, and adaptation is the process where an organism adjusts to its environment over time for survival.

Fragmentation

Meiosis
It's for sure budding- like a star fish or many plants.
Assuming this is a question with 4 different answers...
The answer is B: "Similarities can be seen among related organisms, which shows common ancestry."
Good luck!
