Answer:
somatic cells have highly specific functions
Explanation:
In our body, the major part of cells is irreversibly differentiated into somatic cells. From a cellular point of view, this process of differentiation seems to be an evolutionary disadvantage. However, cellular differentiation is a process aimed at exploiting the genetic variation in order to obtain a highly specialized cell type that is capable of carrying out a specific cellular function. For example, keratinocytes are highly specialized epithelial cells that function by separating the organism from the surrounding environment.
Answer: True
Explanation: The Achilles tendon is the largest and the strongest tendon in the body. When the calf muscles flex, the Achilles tendon pulls on the heel. This allows us to stand on our toes when walking, running, or jumping.

Answer:
The answer is a. chromosomes; proteins.
Explanation:
Genes are segments of chromosomes that code for protein synthesis. Even though in the process, genes do form amino-acids, the final target is to synthesize proteins that play several roles in the cell. Genes are packed in chromosomes so they can fit the cell, otherwise, they would be too long to do so.
