Answer:

Genes called "molecular switch" or master genes have the purpose of control when other genes are expressed (option A).

Explanation:

Master gene is so named because it has the function of controlling the behavior of other genes, organizing their functions and regulating when they can be expressed.

The name of molecular switch is synonymous with the master gene, since its activation determines the genetic regulation necessary to establish cell differentiation and even the determination of the sex of some species.

The other options are not correct because:

B. Master genes do not determine the organization of the genome .

C. Regulation of cell metabolism depends of substances as hormones and enzymes.

D. The rate of translation does not depend on the activity of master genes.

How are muscles the contractile specialists of the body?

Mariana [72]

Muscle cells are uniquely adapted to contractile function due to three main things. FIrst, they have a large capacity for storage of readily available glycogen to use for work. Second, they contain the actin and myosin cross-bridge cycling structure to perform a contraction of a muscle fiber. Finally, each fiber has central nervous innervation to control contraction and relaxation of the muscle fibers.

Answer: (1) It has a tail to travel to the egg (2) contains a nucleus in the head which will fertilise the egg

Explanation: Firstly it has a tail to help it travel to the egg. Secondly it contains the nucleus in the head that will fertilise the egg. Thirdly the acrosome contains enzymes in order for the sperm to penetrate the egg. Finally, the sperm cell is packed with mitochondria to provide the energy needed to reach the egg.
