<span>Anything in an organism's environment that causes it to react is called a STIMULUS. A stimulus is defined as an impulse that evokes a specific functional response from an organism. In living organisms, stimulus can occur both internally and externally. Stimulus generate appropriate response in living organisms. Thus, the correct option is C.</span>
Answer:Secondary succession Secondary succession follows a major disturbance, such as a fire or a flood. The stages of secondary succession are similar to those of primary succession; however, primary succession always begins on a barren surface, whereas secondary succession begins in environments that already possess soil Secondary succession Secondary succession follows a major disturbance, such as a fire or a flood.

The general function of lactase is to regulate cell processes. It is an enzyme, and enzymes act as catalysts of chemical reactions within the body. It regulates different chemical reactions including breakdown of food substances, etc.
Answer:
by using molecular clocks which are based on the mutation rates among molecular sequences (e.g., DNA sequences). The mutation rate can be used to estimate the times of divergence between sequences (in this case, between duplicated sequences in the target species and non-duplicated sequences in the most recent common ancestor).
Explanation:
A molecular clock is a technique that uses the mutation rate (μ) to measure the association between evolutionary rate and time. A mutation rate can be used to estimate the time in prehistory when two or more molecular sequences diverged. For example, assuming a generation time of 20 years, a species that has 100 mutations per generation is divided by 20 years to yield a mutation rate equal to 5 mutations per year. In consequence, the times of divergence can be estimated by dividing half of the target genomic region length (in nucleotides) by the mutation rate (t = d/2 ÷ μ).
