Explanation:
Divide the number of cells in view with the diameter of the field of view to figure the estimated length of the cell. If the number of cells is 50 and the diameter you are observing is 5 millimeters in length, then one cell is 0.1 millimeter long. Measured in microns, the cell would be 1,000 microns in length.
The
Thymocyte progenitors enter the subcapsular region of the thymus as
double-negative cd3- t cells where the double negative refers to lack of
cluster determinants CD4 and CD8. Double-negative cd3- t cells exist as small population
that is 1%-5% of lymphocytes in the lymphoid organs and peripheral blood of
humans and normal rodents.
Answer: oceans
Explanation: oceans have a greater surface area. over 70% of the Earth’s surface is covered by water.
To identify the molecule that accepts 
, Calvin and Benson manipulated the carbon-fixation cycle by either cutting off or cutting off light from cultures of photosynthetic algae. They then measured the concentrations of various metabolites immediately following the manipulation. The acceptor concentration would increase when the is cut off, but decrease when the light is cut off.
The correct option is d.
The process through which living things absorb inorganic carbon from the atmosphere and transform it into organic molecules is known as carbon fixation. These substances are employed as chemical energy storage. For life to continue, it is a necessary process.
Calvin and Benson disrupted the carbon-fixation cycle by either removing or removing light from cultures of photosynthetic algae in order to find the molecule that takes . Following the alteration, they evaluated the concentrations of several metabolites.
