The differences in the mouse populations on Island A and Island B after 20 years will likely be due to genetic drift.
Genetic drift is a mechanism of evolution that refers to random fluctuations in the frequency of alleles (versions of genes) in a population. These fluctuations occur due to chance events such as the random segregation of alleles during meiosis, the random distribution of gametes during fertilization, or the random occurrence of mutations.
Therefore, if the two groups of mice have similar genetic diversity and are placed in isolated environments with no mouse populations, the differences in the mouse populations on Island A and Island B after 20 years will likely be due to genetic drift.

The sweat and oil glands play important roles in regulating body temperature and maintaining skin health.
Sweat glands, also known as sudoriferous glands, serve to regulate body temperature by producing sweat, a mixture of water, salt, and metabolic waste products. Sweating helps cool the body through evaporation and eliminates waste. Oil glands, or sebaceous glands, secrete sebum, an oily substance that lubricates the skin and hair, preventing them from drying out.
Sebum also forms a protective barrier against harmful microorganisms and helps maintain skin's flexibility. However, overproduction of sebum can lead to skin issues like acne. Together, these glands play crucial roles in skin health and temperature regulation.

Complete Question:
What are the functions of the sweat and oil glands ?
B) ozone
C) chlorophyll
D) radiant energy
Plants use their leaves to capture light energy during photosynthesis, water and carbon dioxide are converted by plants into sugar, hence option a is correct.
Plants use glucose as a source of energy and to create other compounds like cellulose and starch and cell walls are constructed using cellulose.
In a process known as photosynthesis, plants use carbon dioxide, water, and sunshine to create sugar and oxygen.
Chloroplasts, tiny compartments found inside plant cells, are where photosynthesis takes place.
Therefore, the removal of carbon dioxide from the atmosphere and utilize water in the production of food make this a significant process for the planet, hence option a is correct.
