GarryVolchara [31]

Answer: the bloodtype of Jesse is A Rhesus D positive

Explanation:

Antigens at present on the blood cells while antibodies are present in the serum. Thus, to prevent agglutination which occurs if the red blood cell antigen is similar to the antibody, the red blood cell of Jesse which has the B antigen will have the A antibodies produced. Thus, since the red blood cell determines the bloodtype of a person, Jesse therefore has the B bloodtype.

In what way do the nervous and endocrine systems differ in a way
Simora [160]

The nervous system communicates through electrical impulses and the communication is very fast. It works in a relay fashion, from point to point comparable to the way the old telephones systems used to work.

The endocrine system communicates by chemical signals via the bloodstream. Hormones are secreted into the blood and extra cellular fluids, then transported to target cells, which must bear a receptor to be able to bind to a specific hormone, and respond. 

Hormones are chemical messengers secreted into blood or extracellular fluid that affect the function of other cells.

Endocrine communication is not quite as fast as the nervous system communication

What best explains the relationship between photosynthesis and cellular respiration?
DiKsa [7]

Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
