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:
a. fatty acids is the correct answer.
Explanation:
fatty acids is NON-polar molecule.
Nonpolar molecules are that molecules which are not soluble in water and fatty acids are not soluble in water.
fatty acids are hydrophobic and the hydrocarbon chain present in fatty acids are nonpolar, thus that's the reason fatty acid is nonpolar.
examples of fatty acids
Answer: A. Fossil
Fossil fuels release gases into the environment. These gases are pollution and they also contribute to global warming and climate change.
I hope that helps!
Environmental science addresses recycling strategy so we utilize our natural resources efficiently. It also provides us with knowledge on how to lead an eco-friendly lifestyle
Answer:
Potential Energy.
Explanation:
Potential energy, stored energy that depends on different parts of the system's relative position. When compressed or stretched, spring has more potential energy.
A stainless steel ball has more energy than it had when it fell to the world. It is able to do more work in the raised position.
Potential energy is a system's property and not a single body or particle. The earth-consistent system and raised ball, for instance, have greater potential energy as the two are more distinct.
