Answer:
Lymphocytes
Explanation:
White blood cells ( leukocytes) is one of the formed elements of blood that provides immunity and protection against the pathogens. Different types of leukocytes are eosinophils, basophils, monocytes, lymphocytes and neutrophils.
Lymphocytes are B cells and T cells of the immune system. B cells produce antibodies against the antigen and T cells kills the harmful cells of the body. by specific cell determinants.These cells are not capable of phagocyte the pathogen.
Thus, the correct answer is option (A).
The answer to this question would be: by producing buffer
The pH of optimal growth of bacteria might be different. Some bacteria can grow in an acid condition called acidophile, other live in base condition called alkaliphiles and the rest live in neutral pH condition called neutrophiles. The bacteria can maintain their internal pH by producing acid, base or buffer. If the surrounding pH is too acid, the bacteria can reduce the H+ concentration by producing base. If the condition is too alkali/base, the bacteria can produce acid by doing fermentation.
Answer:
Explanation:
<h2>
Homotropic effector-</h2>
<h2>Both -</h2>
The phrase 
is relevant and can be applied for homotropic effector molecules since the heterotropic effector molecules have the possibility and affinity to change the sigmoidal curve to a more potential hyperbolic curve contingent upon the allosteric effector to be positive or negative modulator.
The expression isn't relevant for both homotropic and heterotrophic effectors since the two of them can tie to the allosteric site of allosteric enzymatic compounds.
The phrase 
is significant and can be applied for both homotropic and heterotropic effectors.
The expression 
is significant and applied for homotropic effectors just as when substrate molecules tie to the allosteric site of enzyme then it is regarded as homotropic effectors. The heterotropic effectors are effectors apart from substrate molecules.
The phrase 
is not applied and insignificant to none of the heterotropic or homotropic effector molecules since 
is significant for the enzymes that obey the Michaelis-Menten equation, but allosteric enzymes do not obey the Michaelis-Menten equation. Homotropic and heterotropic effectors are viable and efficient for allosteric enzymatic chemicals that don't contain
Are you sure these are the only answer choices? I believe the answer would be Hippocampus, but it's not up there.
