The folds in the stomach lining are called rugae. On these rugae, you will find a thin line of mucous which helps protect the stomach lining. The innermost layer is called Simple Columnar Epithelium.
The main benefit of crossing over is that it increases genetic diversity.
<h2>
Crossing over and
Genetic Diversity</h2>
Crossing over ensures that the daughter cells produced are genetically more diverse than their parent cells.
The exchange of chromosomal segments makes the chromosomes of the daughter cells to be more sophisticated than that of their parents.
Increased genetic diversity in daughter cells increases their chances of survival as more genes are present in their genomes that could potentially make them more adaptable to the environment.
In summary, crossing over increases genetic diversity and genetic diversity increases the chances of survival in the face of changing environment.

Collagen is the structural protein found in skin and connective tissue. This protein is the most abundant protein, that makes up one-third of the protein in the human body. The function of this protein in the skin is to give the skin strength and elasticity, and to replace dead skin cells. In connective tissues it s<span>upports structures and anchor cells to each other.</span>
