<u>Helper t-cells</u> identify antigens and then multiply and trigger the production of other kinds of immune cells.
<h3>What are helper T-cells?</h3>
Helper T-cells are one of the main types of immune cells. They detect infections and activate other immune cells to fight the infection.
Your thymus develops helper T-cells. The thymus is a small gland in the front of your chest. The other types of T-cells include:
- Cytotoxic T-cells, which fight infections.
- Regulatory T-cells, which regulate or suppress other immune cells when needed.
- NKT-cells, which can enhance immunity in general.
<h3>What are the subtypes of helper T-cells?</h3>
When helper T-cells detect an infection, they form into one of two subtypes:
- TH1 helper cells release a molecule that activates a type of cell called a macrophage. Macrophages are specialized cells that help eliminate foreign substances from your body. TH1 cells also activate cytotoxic T-cells.
- TH2 helper cells release molecules that activate B-cells. B-cells create antibodies. They also release cells that cause coughing, sneezing or diarrhea to help your body get rid of foreign substances. This group of T-cells helps generate allergy antibodies.

Diploid chromosomes.
Diploid is basically a cell which contains two sets of chromosomes from each parent. In humans, the diploid chromosomes number is always the same and is always even.
Chromosomes are always in pair, and which is why every human being have an even number of chromosomes. Every child gets its chromosomes from both the parent, half from mother and half from father. All the cells in humans except the sex cells are diploid. Sex cells on the other hand are called haploid.

Explanation:
Their is 30% thymine and a total of 30% adenine, and there is 20% cytosine and 20% guanine.
Answer:
In turn, each nucleotide is itself made up of three primary components: a nitrogen-containing region known as a nitrogenous base, a carbon-based sugar molecule called deoxyribose, and a phosphorus-containing region known as a phosphate group attached to the sugar molecule

Answer:
The water carried the pieces of paper to the sides of the container.
Explanation:
The convection model shows how Earth’s mantle moves Earth’s plates. It also describes how hot rock flows in the Earth's deep interior in order understand fully how this particular flow shapes the surface of the Earth.
The convection model talks about how the temperature of the solid due to an external field such as fluid buoyancy can induce a fluid motion. This explains why water carried the pieces of paper to the sides of the container.
