We need to minimum buffering capacity is required so that the pH value of the samples analyzed does not have any influence on the system, 

What would happen if we used the higher buffering concentration

a) more electric power is applied, resulting in higher heat development. 

b) less electric power for less time  is applied, resulting in very high  heat development

c) higher buffering concentration need more electric power resulting increases in the temperature will increase the mobility and rate of migration of ions.

d) using the higher buffering concentration shows no affect at all

Following statement regarding to acrosome reaction in sea urchin.

A. Activation of the acrosome reaction serves as a barrier to intraspecies fertilizations.

B. The acrosome reaction is initiated by sulfate-containing polysaccharides in the egg jelly that bind to specific receptors located directly above the acrosomal vesicle on the sperm cell membrane.

C. These polysaccharides are often highly species specific, but egg jelly factors from one species of sea urchin generally activate the acrosome reaction in closely related species.

D. The elevated Ca2+ level in a relatively basic cytoplasm triggers the fusion of the acrosomal membrane with the adjacent sperm cell membrane, releasing enzymes that can lyse a path through the egg jelly to the vitelline envelope.

Before oogenesis begins, the oogonium divides four times with incomplete cytokinesis, giving rise to 16 interconnected cells in drosophila. These 16 germline cells, along with a surrounding epithelial layer of somatic follicle cells, constitute the egg chamber in which the oocyte will develop. These germline cells include:
