The structure of the skin is an effective barrier against bacteria. The multiple layers of epidermis, while can be invaded by foreign organisms, has a high turnover rate which means it is constantly shedding, therefore even the bacteria is shed protecting the body. Lastly, the skin's lipids maintain an acidic pH which slows and stops growth and replication of bacteria.
Answer:
Chimpanzees.
Explanation:
DNA sequence similarity is helpful to determine the evolutionary relationship between the organisms. The evolutionary tree can easily be constructed if the percentage of the DNA sequence similarity is known.
The human shows 98.8% sequence similarity with chimpanzee. The sequence similarity between human and gorilla DNA is 98.4%. This means Chimpanzee are more closely related to humans than gorillas.
Thus, the answer is chimpanzee.
<span>Body fat directly influences total body water. The influence of age, gender and fitness is also relative.
