Answer:
Red blood cells in blood type A-positive individuals have the A antigen, and generate antibodies against the B antigen (option B).
Explanation:
The basis of compatibility by blood group, according to the ABO system, is due to the presence of surface antigens A and B in the red blood cells. When a specific antigen is present, the body recognizes it as its own, while the other antigen will be recognized as foreign, and will induce antibody synthesis.
Blood types are determined by the presence, or absence, of these surface antigens A and B, generating antibodies against the antigens it does not possess, which can be summarized:
- <u>Blood type A</u><u> </u>has surface antigen A, but antibodies against B.
- <u>Blood type B</u> has surface antigen B, and antibodies against A
- <u>Blood type AB</u> has both A and B antigens, so it does not generate antibodies
.
- <u>Blood type O</u> has no antigens, but can produce antibodies to both antigens.
Individuals' blood type is a genetically inherited trait

Hi, sounds like it would turn into B). Metamorphic Rock. Igneous rocks are only formed when melted rock hardens and solidifies. Sediimentary rock is formed when sediment is deposited out of air, ice, wind, gravity or even water. I Doubt it would remain a sedimentary rock so the best answer would be metamorphic rock. Hope this was correct. :)
Answer:
ZBWCYAX
Explanation:
Equation for the intermediates: Z↔W↔Y↔X
1) B catalyzes the breakdown of Z, therefore inhibiting B leads to the build up of Z.
2) If enzyme C is inactive then the organism will not receive Y to grow, thus Y is a by-product of C.
3) If A is inhibited then W, Y and Z build except for X, thus it make sense that A catalyzes a reaction that leads to X as a by-product.
4) Inhibiting C leads to the reaction toward making Z and W, thus it catalyzes the breakdown of C directly and Z indirectly.
