Answer:
Because T-cell-independent antigens do not activate helper T cells, they fail to induce B cell memory, affinity maturation, or class switching, all of which require help from T cells. They therefore mainly stimulate the production of low-affinity (but high-avidity) IgM antibodies.
Explanation:
According to Mendel Law of segregation all offspring in F1 generation will white wool. However, in F2 generation three will be white wool and only one offspring will be spotted wool.
Phenotype (parental generation) White wool x spotted wool
Genotype TT tt
F1 generation Tt, Tt,Tt, Tt (white wool)
Self cross Tt x Tt
F2 generation TT, Tt, Tt, tt
white wool = 3
spotted wool = 1
Answer:
Sodium helps to maintain the normal plasma osmolarity as well as blood pressure.
Explanation:
The given points that can be applied for maintaining electroneutrality is
1 low sodium stimulates the secretion of aldosterone .
2 regulates plasma osmolarity
low sodium stimulates the secretion of aldosterone from the adrenal cortex that boost the reabsorption of Na+ ions from the glomerular filtrate
Maintaining electronutrality is the other meaning regulating plasma osmolarity.

I believe the correct answer from the choices listed above is the last option. The term that best fits the empty cell in the diagram would be the atmosphere. The atmosphere is one of the reservoir of water aside from the ocean and the lands.
