Given the enormous heterogeneity of antigen receptors expressed on the populations of naive B and T lymphocytes, the adaptive immune response relies on a process whereby the rare lymphocyte that binds to the antigen is first induced to proliferate, before it can perform its effector function. For B cells, there is a clever mechanism that ensures that the specificity of the antibody secreted by the plasma cell will recognize the same pathogen that initially stimulated the B cell antigen receptor and induced B cell proliferation. This mechanism is:
Answer:
The naïve B cell expresses a membrane-bound form of the antibody as a receptor and secretes that same antibody when it differentiates into a plasma cell.
Explanation:
Naive B cell is a type of B cell that has still not been exposed to the antigen. The B cell receptors (BCRs) are transmembrane proteins composed of 1-a surface immunoglobulin molecule capable of recognizing the antigen, and 2-two transmembrane subunits that transduce the signal. When a B cell binds to antigen with its BCR, the B cell will proliferate and differentiate into a plasma cell. This plasma cell then releases antibodies, which are soluble forms of the BCR where the transmembrane domain that anchors the antibody protein to the membrane of the B cell is eliminated.

What is a function of the integumentary system?
1 forms blood clots
2 grows new tissue
3 absorbs water
4 break down chemical bonds in food
Answer:
absorbs water is a function of the integumentary system. hope it help you.
A function of the integumentary system is to grow new tissues. Thus, the correct option B.
What is the Integumentary system?The integumentary system may be defined as a unique type of system that primarily consists of the skin, hair, nails, and exocrine glands. It is the set of organs that construct an outermost layer of an animal or human body.
The integumentary system plays a significant role in the growth of new tissues within the body. The cells of the skin generally hold the mechanism of renewal or replacement of injured or damaged cells which are present on the epidermis part of a specific organ.
The integumentary system also protects the body from infections, and injuries provide defense against pathogens, etc.
Therefore, a function of the integumentary system is to grow new tissues. Thus, the correct option B.

The Calvin Cycle can best be described as which type of reaction?
Answer:
In plants, carbon dioxide (CO2) enters the chloroplast through the stomata and diffuses into the stroma of the chloroplast—the site of the Calvin cycle reactions where sugar is synthesized. ... This type of reaction is called a reduction reaction, because it involves the gain of electrons.
A postsynaptic neuron has three presynaptic inputs - from neurons X, Y and Z. When X, Y, and Z are stimulated simultaneously, the postsynaptic neuron reaches threshold and undergoes an action potential. What is this process called?
Answer:
Summation
Explanation:
Presynaptic neurons release chemical signals called neurotransmitters into the synaptic cleft in order to trigger graded potentials in the postsynaptic neuron. Some neurotransmitters produce excitatory post-synaptic potentials, whereas other neurotransmitters generate inhibitory post-synaptic potentials. Summation refers to the process that determines whether an action potential is generated by the combined effects of excitatory and/or inhibitory signals. The summation can be temporal or spatial regarding the number of cells communicating with the neuron. Temporal summation occurs when a presynaptic terminal is stimulated repeatedly in rapid succession. On the other hand, spatial summation occurs when excitatory potentials fire from different presynaptic neurons.

Explanation:
Cystathioninuria can be caused by two different mutations in the enzyme cystathionase. Cystathioninuria caused by mutation 1 can be overcome by providing cells with increasing concentrations of the coenzyme pyridoxal phosphate. Which of the following statements describe the most likely changes in the binding affinities of the two mutant enzymes?
A. Both mutant enzymes have lost the ability to bind the substrates.
B. The enzyme with mutation 1 has lost the ability to bind to the substrates, whereas the enzyme with mutation 2 has lost the ability to bind to pyridoxal phosphate.
C. The enzyme with mutation 1 has decreased affinity for pyridoxal phosphate, whereas the enzyme with mutation 2 has lost the ability to bind to the substrates.
D. Both mutant enzymes have lost the ability to bind pyridoxal phosphate.
Answer:
C. The enzyme with mutation 1 has decreased affinity for pyridoxal phosphate, whereas the enzyme with mutation 2 has lost the ability to bind to the substrates.
Explanation:
A coenzyme is an organic cofactor that binds with an enzyme in order to initiate or aid the function of the enzyme. A coenzyme binds to the active site of the enzyme (where the reaction occurs), thereby triggering its activation by modifying protein structure during the reaction. Some examples of coenzymes include Coenzyme A and Adenosine triphosphate (ATP). Pyridoxal phosphate is a coenzyme (it is the active form of vitamin B6) that is required for the function of cystathionase. Moreover, cystathionase is an enzyme that enables cells the synthesis of cysteine from methionine (transsulfuration pathway). The binding of pyridoxal phosphate to the enzyme increases the binding affinity of the enzyme for the substrate, thereby influencing its activity. In this case, it is expected that mutation 1 reduces the binding affinity of the enzyme to the cofactor, and thereby the cofactor is required at a higher concentration to restore normal enzyme activity.
what are the advantage of the presence of hydrogen in large scale in the sun ?
hydrogen is essential to nuclear fusion. hydrogen is the fuel the sun burns. we don't have to burn solar energy, so there's no smoke and pollution
Answer:
Hydrogen fusion reaction is the one which provides so much light and heat (in short, energy) which escapes into space and spread. If Hydrogen on sun ends, It will lose its warmth (and may be soon become a planet, but will surely be a dead star).

The two most important environmental factors affecting animals are biotic and abiotic.
What is the Environment?The environment may be defined as anything which is present in the surrounding of a living organism. The term environment was given by Carlyle.
Biotic factors include producers which are autotrophic in nature. Herbivores, Carnivores, omnivores, decomposers, parasites, etc.
Abiotic factors are generally long-lasting environmental conditions such as temperature, light, rain, fire, winds, etc., and topographic factors like mountains, hills, plains, desert, etc.
Therefore, the two most important environmental factors affecting animals are biotic and abiotic.
