Answer:
the function of cell membrane is to provides protection for a cell.
Answer:
c silent mutation
Explanation:
The given mutation changes the genetic code "GGC" to "GGA". According to the genetic code table, both "GGC" and "GGA" code for glycine. Since both mutated and normal codon code for the same amino acid, that is glycine, the mutation would not have any effect on the function of the gene.
The point mutation that does not affect the function of a gene is called a silent mutation. Hence, the given example represents the silent mutation.

Meory T cells are defined as a subset of infection including cancer-fighting T cells
Answer and Explanation:
Internal fertilization is characterized by sperm fertilizing the egg within the female. More protection against outside environments and predators, and therefore a higher chance of surviving until birth
. The young develop within the female, receiving nourishment from the mother’s blood through a placenta. Less chance of desiccation of gametes. Internal fertilization also enhances the fertilization of eggs by a specific male since the females are more selective of their mates thus increasing chances of gametes meeting
. Even though fewer offspring are produced through this method, their survival rate is higher.
