Which if any of the blood samples can the patient with type b+ blood receive

A type B+ patient can receive blood from:

(a) a type B+ blood sample

(b) a type O+ blood sample

(c) a type B- blood sample

(d) a type O- blood sample

Explanation:

There are four blood types known as A, B, AB and O

Different blood types have proteins known as antigens which are attached to them. Type A has antigen A, type B has antigen B, type AB has both antigens A and B, while type O has neither A nor B antigens.

The human immune system naturally produces antibodies against antigens that are not found in its own blood, hence blood type A produces antibodies B antigens, type B produces no antibodies against antigen A or B and type O produces antibodies against antigens A and B. Hence, a type A patient can only receive a type A or type O blood; a type B patient can only receive a type B or O blood; a type AB patient can receive a type A blood, a type B blood or a type O blood; a type O blood can only receive a type O blood.

Rhesus is an antigen that occurs naturally in the blood of some humans (85% statistically). Humans having this antigen are rhesus positive and bear the "+" sign in front of their blood type, while a rhesus negative human bears the "-" sign in front of their blood type. A rhesus + patient can receive a rhesus + or rhesus - blood but a rhesus - patient can only receive a rhesus - blood.

Therefore, a type B+ patient can only receive blood from:

(a) a type B+ blood sample

(b) a type O+ blood sample

(c) a type B- blood sample

(d) a type O- blood sample

answer: that would be cheating

explanation:

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.
