Although they exhibit a high degree of genetic similarity, humans and chimps are distinct mainly due to variations in

The genetic difference between humans and chimpanzees is  about 0.1%, on average. Although this huge genetic similarity, the differences between humans and chimpanzees can be attributed to how these genes are regulated. The same genes are expressed in the same brain regions in human, chimp, and gorilla, but in different amounts. Thousands of differences like these affect brain development and function and help explain why the human brain is larger and smarter. There is also a slight difference in genes (the 0.1% difference) which could seem small but has a big difference.

answer;

c. a tree whose roots are surrounded by wet sand.

explanation;

water stress is an important factor limiting the growth and productivity of forests.water stress is the most often cited cause of poor survival and growth of woody landscape plants.

-insufficient soil moisture is the most common form of water stress, but excess moisture that leads to poor soil aeration (hypoxia) can also result in reduced plant vitality. a tree whose roots are surrounded by wet sand would be least likely to experience water stress.
