Answer:

can be caused by interaction with MHC/peptide in the absence of costimulation

Explanation:

T cells represent a class of white blood cells (lymphocytes) that have a major role in the adaptive immunity of the organism against specific pathogens. Peripheral tolerance is a type of immunological tolerance aimed at ensuring B and T cells that escaped from the central tolerance mechanism do not produce autoimmune diseases. Some populations of lymph node cells can induce peripheral tolerance in T helper cells (Th cells, CD4+ cells) by the presentation of peptide-MHCII (major histocompatibility complex type II) complexes acquired from dendritic cells. These dendritic cells are antigen-presenting cells that play a key role in adaptive immunity, which are well-known to induce CD4 and CD8 T cell tolerance in response to antigens (peptides/proteins).

Answer:

Abiotic factors, such as temperature, water, sunlight amounts, and regional terrain, directly effect biotic factors. Biotic factors are the living components of an ecosystem which include primary producers, consumers, and dexomposers.

Abiotic factors can effect organisms in many ways. Hey can effect primary producers negatively if there is too little sun, water, or nutrients in the soil. However, if there is too much of any one of these, they can still be negatively effected. With primary producers, it’s all about balance.

while consumers do not directly require the above conditions, they do rely on the plants and animals that feed on said plants to survive. If the plants do not have correct nutrients, they will not either. As far as terrain goes, they adapt to better cope with the environment. If they live in an aquatic enviromment for example, they acquire ways to more efficiently move through the water to look for food.

Decomposers rely on the remains of dead plants and animals in order to survive. They feed off of dead matter and the waste gets deposited into the soil. This in turn helps to give the soil its nutrients, and so the cycle continues.

Everything in nature is reliant on each other. This delicate balancing act is both beautiful and so very fragile. If one organism is removed, the entire ecosystem could suffer. This is why it is so critical to protect the environment we share with every other living creature on this earth.

Which type of species is the first to occupy a bare site?
Evgen [1.6K]

Answer:

pioneer species

Explanation:

Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. The first inhabitants are lichens or plants—those that can survive in such an environment. Over hundreds of years these “pioneer species” convert the rock into soil that can support plants.
