Some genetic mutations can be completely harmless, while others are life-altering. Mutations happen when DNA is copied incorrectly. This causes an irregularity in the DNA. Mutations are permanent changes to genetic material that can be passed on to offspring. These changes happen randomly and can occur in any type of gene. While some mutations are not harmful (hazel eyes, for example), many mutations have harmful effects on health.
Answer:

Explanation:
There are three main aspects of photosynthesis
(i) Absorption of light energy by chlorophyll.
(ii)Photolysis of water
(iii) combination of water and CO2 to form carbohydrates.
The second and the third aspects of photosynthesis are controlled by the availability of water. Plants absorb water from the soil through their root hairs and it moves up to the leaves by capillary action.
Hence, if there is no rain (drought), the soil will lack water and so does the plant thereby hindering the uptake of water for the second and third stages of photosynthesis.
the Arizona poppy, lie dormant during drought only to germinate, grow, flower, and yield seeds a few weeks after the rains return.
