The option that is most likely to result in an action potential at a postsynaptic neuron is D) many EPSPs and few IPSPs.
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:
(1) as organic molecules in living and dead organisms found in the biosphere; (2) as the gas carbon dioxide in the atmosphere
Explanation:
Answer:
D.
Explanation:
The data set has no correlation and cannot be accurately represented with a linear equation.
there seems to be no relation between the numbers
if you know the x value, you can't really guess what its y value is (no correlation)
It is necessary to phosphorylate a glucose molecule so as to trap glucose inside the cell, to make ATP, and to facilitate enzyme building. When insulin is released from the pancreas after a meal, it signals the tissues to uptake glucose. When glucose enters the cells via glucose transporters, there is a chance for them to leave the cell. If the body is in need of energy, and the breakdown of glucose will provide that energy, the body does not want the glucose to leave the cell and that is why the glucose is phosphorylated by ATP to become glucose-6-phosphate, which now bears a charge.
