Answer:

Your immune system is designed to protect you against pathogens.

Explanation:

Immune system has a specific type of cell which provides protection against harmful microbes such as bacteria and viruses etc. These special cells are called white blood cells. White blood cells are also called leukocytes. These white blood cells are formed in the bone marrow. When a pathogen enters into the body, these white blood cells attack on them and kill them.

A huge amount of water − 7 to 9 l − moves from the blood into the bowel every day, through osmosis and digestive secretions. sin
Alexus [3.1K]
The event order should be:

1. Ingesting food, the small bowel filled with food solutes and become hypertonic. It will attract water from the blood which is hypotonic
2. Food digested, some of it absorbed. The osmotic pressure inside bowel will be reduced.
3. All food is absorbed, the osmotic pressure reduced significantly makes it hypotonic. The blood attracts water as it is hypertonic. This will increase the blood volume

Mkey [24]

Answer:

Functions of epithelial cells include secretion, selective absorption, protection, transcellular transport, and sensing. Epithelial layers contain no blood vessels, so they must receive nourishment via diffusion of substances from the underlying connective tissue, through the basement membrane

Magical ability is a dominant trait controlled by two loci. To be able to perform magic, a person would need to carry at least o
dangina [55]

Answer:

b. aaBb x AAbb

Explanation:

According to the information in this question, the trait for magic ability is controlled by two genes, each comprising of two alleles i.e. A,a and B,b. However, to be able to perform magic, a person would need to carry at least one copy of the dominant allele (A and B) on each of the two loci.

Hermione Granger has magical ability but neither one of her parents does. This means that although Hermione can perform magic, none of her parents can. Genetically, it means that Hermione posseses at least one copy of the dominant allele on each of the two loci i.e. her genotype is A_B_.

This is only possible in Hermione if her parents transferred a dominant allele at each loci to her. This means that the possible genotypes for Hermione Granger’s parents are aaBb (no magical ability) x AAbb (no magical ability). See the punnet square attached where the probability of producing offsprings with magical ability is 1/2 or 50%.
