<h2>Answer and Explanation </h2>
The genetic recombination is a biological process in which the recombination of homologous DNA strand occurs. There are three types of genetic recombination in human being that is :
Human Reproducation that is by introducing new gene combination to the population.
By cell Mutation is it that is changes in the DNA.
By Gene flow it is that is by movement of a gene from one population to another population.
The cell membrane is composed of a phospholipid bilayer.
The cell membrane is primarily composed of a mix of proteins and phospholipids
Phospholipids are a major component of cell membranes. They a head and a tail. The head is hydrophilic (attracted to water) and the tail is hydrophobic (repelled by water).
They form a bilayer in which their hydrophilic heads face the aqueous cytosol and extracellular fluid while their hydrophobic tails face away from the cytosol and extracellular fluid.
The lipid bilayer is semi - permeable
Answer: [B]: "proteins" .
