My two last biology questions

Question

Aspirin,ibuprofen and other aspirin alternatives relieve pain by

a)repairing damage to neurons in the pain centers of the brain

b)increasing the activity of the immune system

c)interfering with the synthesis and the release of prostaglandins

A person with antigen A on their red blood cells can give blood to someone with blood type(s)

a)A and AB

b)B and AB

c)AB

d)O

Answer 1

OOOOOOOOOOOOONNNNNNNNNLLLLLLLLLLYYYYYYYY... group A and AB

a)A and AB this switch better than switch c

if you have antigen A just can donor to A and AB

Answer 2

1st) (c)

2nd) (a)

Answer 3

Question:

1) c-  The class of pain relievers you are talking about is called non-steroidal anti-inflamatory.  They do not increase immune system activity nor can they repair neurons in the brain. Nonsteroidal anti-inflammatory drugs (NSAIDs) block the Cox enzymes and reduce prostaglandins throughout the body. As a consequence, ongoing inflammation, pain, and fever are reduced.

2) a)  your blood type refers to a certain group of closely related protiens in your blood.  If you donate blood to a person that does not have this protien their body will buildup anti-bodies to it and attack the transferred blood.  Thus if you are type A you can only give to someone that has A or a combination including A.

Answer 4

C) Aspirin's ability is to suppress the production of prostaglandins. which interrupts the transmission of pain information to the brain.

A) Blood group A individuals have the A antigen on the surface of their RBCs. Therefore, a group A individual can receive blood only from individuals of groups A or O (with A being preferable), and can donate blood to individuals with type A or AB.

Answer 5

C to the first one and A to the second one
