Induction of peripheral tolerance in T cells: Please choose the correct answer from the following choices, and then select the submit answer button. can be caused by interaction with MHC/peptide in the absence of costimulation. can be caused by costimulation in the absence of MHC/peptide. usually leads to apoptosis. The first and third answers describe this form of induction. The second and third answers describe this form of induction.
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).

How do the organs of the excretory system work together to eliminate potentially harmful wastes from the body?
Answer:
This is the job of the excretory system. You remove waste as a gas (carbon dioxide), as a liquid (urine and sweat), and as a solid. Excretion is the process of removing wastes and excess water from the body. Recall that carbon dioxide travels through the blood and is transferred to the lungs where it is exhaled.

engulfment.
immunity.
inflammation.
Answer:
Dendritic cells are the most efficient antigen-presenting cells. They take up antigens and pathogens, generate MHC-peptide complexes, migrate from the sites of antigen acquisition to secondary lymphoid organs and, finally, they physically interact with and stimulate T lymphocytes. So it would most likely be inflammation.

Explain how a concentration gradient, a membrane protein, and hydrogen ions work together to provide a mithochondrion with energy.
Answer:
Mitochondria within the electronic transport chain, are responsible for producing the energy that the cell needs, adjusting its operation to meet the metabolic needs of the body.The mitochondrion is the place where oxygen is consumed from aerobic organisms through various electron carriers and proton translocators (H +).
Explanation:
The lipid matrix of the membrane provides an impermeable barrier to ion translocation, as well as a topological organization to the catalysts in the membrane matrix that allows them to transport both e- and ions within and across the membrane in vector form. The transformation of oxidative energy into other forms of energy is carried out, initially, by generating a transmembrane electrochemical potential difference of H + ions (protomotive force). This force is the product of the asymmetric distribution of H + on both sides of the membrane, as those are translocated through it by the enzymatic complexes of the respiratory chain.The protomotive force is made up of two closely related components: one, function of the difference in chemical concentration of hydrogens across the membrane (a pH gradient) and another, dependent on the difference in electrical charge of H + ions on both sides of it (an electrical potential gradient). Gradients of electrical charge and chemical potential produce a field in which a force is exerted that tends to attract previously expelled protons into the mitochondria. It is the enzymatic complex of ATPase, the means by which the thermodynamically reversible translocation of H + ions is catalyzed. At the same time, the chemical activity of the H + on both sides of the membrane causes a change in the equilibrium constant of the enzyme, inducing it to catalyze the synthesis of ATP.

The cells of both unicellular and multicellular organisms carry out life processes. With respect to life processes, what advantage do multicellular organisms have over unicellular organisms? 1) Their cells reproduce more quickly. 2) Their life processes occur over a shorter time period. 3) Their cells can specialize in certain functions. 4) Their cell division is more efficient.
Answer:
Their cells can specialize in certain functions
Explanation:
This because multicellular organisms are organisms that are made up of several cells which aid it's complexity and lifespan. The cells in muiticellular organisms carries out specialise function or task which give them long lifespan. This long life span is achieved because of various cells that maintain their processes, the cells forms tissues, tissues to organs, organs to system and they all perform different specialized functions.

Answer:
1.The period during which a heart chamber is contracting is called systole.
2. The period during which a heart chamber is relaxing is called diastole.
3. During ventricular contraction, the AV valves (tricuspid and mitral valves) are closed.
4. During ventricular relaxation, the AV valves are open.
5. The pulmonary and aortic valves open when the pressure in the ventricles exceeds the pressure in the pulmonary trunk and aorta.
6. The first sound of a cardiac cycle occurs when the atrioventricular valves are closing.
7. The second sound of a cardiac cycle occurs when the semilunar valves are closing.
Explanation:
We can divide the heart cycle into two parts the systole and the diastole. The systole happens when the heart walls contract, and the diastole when these relax.
The relaxation and contraction allow the flow of blood into the different heart chambers.
During diastole, blood flows to the right atrium from the vena cavae superior and inferior, and the coronary veins and to the left atrium from the pulmonary veins. The blood accumulated in the atriums causes the AV valves to open, and blood flows to the ventricles. In this part, the atrium pressure exceeds the ventricular pressure allowing the blood's flow. When the atriums contract, the remaining blood that was in them, goes to the ventricles. Throughout all this process, the pulmonary and aortic valve is closed due to a pressure difference.
During ventricular systole, there are two phases. First, the ventricles contracts themselves, and the ventricular pressure increases, being higher than the atrium pressure. As a consequence, the AV valves close. During this first phase of contraction, there is not enough pressure to open the pulmonary and aortic valves. In the second phase, the ventricles completely contract themselves, the ventricular blood pressure increases. It becomes higher than the pressure in the aortic and pulmonary valves. As a consequence, the blood pushes the valves open, and blood goes out of the heart. Then, the difference in pressure between the ventricles and the pulmonary trunk and aorta causes the valves in these areas to close.
The first sound that we listen to is the S1 and is during the ventricular contraction that closes the atrioventricular valves. The second sound is the S2, and it happens when the semilunar valves close, also knowns as aortic and pulmonary valves. S2 occurs during diastole once that the blood is out of the ventricle and the contraction has finished.
A chemist has discovered a drug that blocks an enzyme that catalyzes some of the reactions of glycolysis. He wants to use the drug to kill bacteria in people with infections. However, he cannot do this because __________. A chemist has discovered a drug that blocks an enzyme that catalyzes some of the reactions of glycolysis. He wants to use the drug to kill bacteria in people with infections. However, he cannot do this because __________. bacteria are facultative anaerobes; they usually don't need to perform glycolysis human cells also perform glycolysis; the drug might also poison them glycolysis can occur without the action of enzymes bacteria do not perform glycolysis glycolysis produces so little ATP that the drug will have little effect
Answer:
human cells also perform glycolysis; the drug might also poison them
Explanation:
Glycolysis is the first stage of cellular respiration, which is performed by every living thing to release energy for their cell's use. Glycolysis occurs in the cytosol, hence, it is undergone by every living organism whether prokaryotic or eukaryotic.
According to this question, a chemist is said to have discovered a drug that blocks an enzyme that catalyzes some of the reactions of glycolysis. His main aim is to use the drug to kill bacteria in people with infections. No matter his good intentions, he cannot use the drug on people because of its inhibitory effect on glycolytic reactions, which is also performed by human cells.
Therefore, the chemist cannot use the drug because human cells also perform glycolysis and the drug might also poison them.
What force or forces constitute the fundamental source of energy that generates wind movement and circulation?
Answer:
The movement of wind is the result of the action of one or more forces on a particle of air, fundamentally the forces of the solar radiation, pressure gradient, coriolis, friction and centrifugal are recognized.
Explanation:
Air movement is caused by differential heating of the earth's surface and the atmosphere, which presents significant variations in time and space. Wind specifically refers to the horizontal movement of air parcels (which reach great distances and can persist on different time scales)Solar radiation is absorbed by the Earth, and this process is uneven. This irregular heating is what generates the wind. Pressure Gradient Force is determined by the pressure differences between two points in the atmosphere and tends to move the parcels of air from high to low pressure centers, in order to achieve barometric equilibrium. This force is responsible for causing the initial movement of the air. The Coriolis Force is an apparent force that occurs perpendicular to the direction of movement, generating a deviation in the wind path due to the rotation of the Earth (around its axis with an angular velocity). Centrifugal Force manifests itself as a radial pushing action from the center of a circle. In the atmosphere, it occurs in high- and low-pressure systems, leading outward from high- or low-pressure centers. The Friction Force is caused by the friction of the air with the earth's surface, causing a delay in the flow of air masses and changes in the direction of movement.
Because all of the cells in a multi-cellular organism come from a single cell, all of its cells will have the same number of
Answer:
Chromosomes
Explanation:
Multicellular organism are organisms that have more than one cells in their body. However, from the very beginning of every living organism including multicellular organisms, only ONE cell is required. In the case of multicellular organisms, this one cell undergoes division by mitosis to form other cells.
Since the cells divide by mitosis i.e 1 forms 2, 2 forms 4 etc.,. each of the cells are genetically identical to one another. Hence, this means that all the cells will contain the same number of chromosomes in their genome. For example, a dog as a multicellular organism has cells that emanate from one cell. If that one cell contain 39 chromosomes, all cells in the dog will also contain 39 chromosomes.
