antigen processing involves the breakdown of protein antigens and the subsequent association of peptide fragments on the surface of antigen-presenting cells with MHC class I or class II proteins.

Antigen is any foreign particle or molecule that can trigger a n immune response in the body.

After the body encounters the antigen cells like macrophages, B cells and dendritic cells will recognise and destroy them. The parts of the antigen will be presented by the macrophages to the T cells and hence they are also called Antigen presenting cells.

Antigen presenting cells will showcase the antigen or its part to the T cells. This is done with the help of a protein called major histocompatiblity complex or MHC complex proteins.

MHC proteins are present on cell surface and holds the antigens to showcase them to T cells.

poizon [28]

Eukaryotes that reproduce through reproduction require two cells to contribute genetic material for the production of the next generation is true.

<h3>What is genetic material?</h3>

Genetic material is defined as anything with genetic information that can be passed from one generation to the next, whether it be from a plant, animal, microbial, or other source.

It can also be defined as the means by which knowledge is passed from one generation to another.

There are basically three types of genetic materials.

  • DNA
  • RNA
  • Genes

Some of the properties of genetic materials are:

  • It has to be secure.
  • When necessary, it must be able to be expressed.
  • It must be able to replicate information accurately.
  • It must be passed unchanged from father to offspring.

Thus, eukaryotes that reproduce through reproduction require two cells to contribute genetic material for the production of the next generation is true.

Describe and explain how blood flows from the foot to the lungs.
Natali5045456 [20]

Answer:

lungs:

The blood first enters the right atrium.

The blood then flows through the tricuspid valve into the right ventricle.

When the heart beats, the ventricle pushes blood through the pulmonic valve into the pulmonary artery.

The pulmonary artery carries blood to the lungs where it “picks up” oxygen.

It then leaves the lungs to return to the heart through the pulmonary vein.

The blood enters the left atrium.

It drops through the mitral valve into the left ventricle.

The left ventricle then pumps blood through the aortic valve and into the aorta. The aorta is the artery that feeds the rest of the body through a system of blood vessels.

Blood returns to the heart from the body via two large blood vessels called the superior vena cava and the inferior vena cava. This blood carries little oxygen, as it is returning from the body where oxygen was used.

The vena cavas pump blood into the right atrium and the cycle begins all over again.
