__________identify antigens and then multiply and trigger the production of other kinds of immune cells.
solong [7]

<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:

  1. 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.
  2. 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.

Which of the following is an example of conservation by sustainable land use?
faltersainse [42]

Using plants to remove toxins from the ground in an environment is an example of conservation by sustainable land use.

In order to meet human needs both now and in the future, sustainable land use provides a fair and balanced distribution of land, water, plants, biodiversity, and other environmental resources among the numerous competing claims.

In order to protect, conserve, and use resources (soil, water, and biodiversity) sustainably, as well as to restore degraded natural resources and their ecosystem functions, sustainable land management (SLM) entails measures and practices that are tailored to biophysical and socioeconomic conditions.

SLM practices include:

Control soil erosion, boost soil fertility, manage soil organic matter for soil carbon sequestration, avoid land conversion and safeguard vulnerable areas; prevent land degradation; and recover degraded soils.
