The polarity of the water molecule helps it to cohere to nearby water molecules, forming a skin over it.
The correct answer is: D. damage to nerves that control the stomach.
The vagus nerve is a cranial nerve that controls stomach contractions and thus, the movement of the food. When the vagus nerve is damaged, the muscles of the stomach do not function properly, so gastroparesis occur. Consequently, food then moves slowly or even totally stops moving through the digestive tract.
Crossing over, or recombination, is the exchange of chromosome segments between nonsister chromatids in meiosis. Crossing over creates new combinations of genes in the gametes that are not found in either parent, contributing to genetic diversity.
Answer:
First replication of DNA occurs, after that division of the cell.
Explanation:
Before dividing into two daughter cells, the replication of genetic material i. e. DNA molecules occur in which same copy of DNA molecule is produces. After the replication process, the parent cell divides into two daughter cells having each the copy of DNA molecule. Binary fission is a type of asexual reproduction in which a single cell divides into two daughter cells and both the daughters cells are identical to the parent cell.
Cellulose is a carbohydrate which is present in the plant cells. The cellulose is a polymer with glucose as the monomer units. The monomer units of cellulose is attached by the beta linkages. The cellulose provides structural support to the plant cells by forming micro-tubules. The humans cannot eat the diet rich in cellulose because they lack the enzymes that are needed to digest them. Some animals, such as cows and termites have these enzymes but not the humans.
Hence, the answer is 'people cannot digest cellulose'.
