Answer:
The correct answer is option d. "Polyclonal antibodies".
Explanation:
The enzyme-linked immunosorbent assay (ELISA) is very useful in comparison to other immunoassay methods for being highly accurate, sensitive and specific. Polyclonal antibodies for the detection step could be used on order to ensure that a mutation in a single surface protein would not make obsolete an ELISA used to detect a new viral pathogen. Unlike monoclonal antibodies, polyclonal antibodies are a collection of antibodies that recognize multiple epitopes of the same antigen. Therefore, a mutation in one epitope that affects the binding of one antibody would not affect the bind of the others and the ELISA will be able to recognize the pathogen.
Answer:
The plants are consumed by the deer and bear.
Explanation:
Food Web is nothing but interconnection of two or more food chains.
Deer being a herbivore, eat plants directly. So, Deers are primary consumers as plants are producers in any food chain or food web.
So we can say that the plants are consumed by the deer and bear.
Bear being omnivore eats both plants and animals. That are primary as well as secondary consumers.

Answer:
3
Explanation:
Heterozygous mice at both loci would be BbAa genotype.
B (black) is dominant over b (white) but the presence of A results in agouti.
Crossing two heterozygous:
BbAa x BbAa
Progeny
<em>9 B_A_ - Agouti</em>
<em>3 bbA_ - agouti</em>
<em>3 B_aa - Black</em>
<em>1 bbaa - white</em>
Hence, 3 out of 16 progeny will be black in color.

Functional groups are a group of molecules attached to a carbon-based core of an organic molecule. Key functional groups are 3. phosphates
