Answer:

C

Explanation:

D in my opinion wouldn't be correct because a vaccine is for if you come in contact with the sickness you are more protected and helps build immunity. So healthy people get them to try and build immunity against said vaccine. Like if you have the flu, your body is fighting. In the Flu vaccine parts of the flu are in the vaccine to help your body learn to become immune. So option C.

Sorry if this is confusing, hope it helps!

In the absence of oxygen, what is the net gain of ATP for each glucose molecule that enters glycolysis?
Naily [24]

Answer:

2 molecules of ATP

Explanation:

Glycolysis is the anaerobic process (no oxygen required) used in the breakdown of glucose to extract energy. It occurs in the cytoplasm of both prokaryotic and eukaryotic cells. It is the first step of cellular respiration.

Glycolysis is subdivided into two phases: the first phase uses energy (ATP), while the second phase produces it together with pyruvate and NADH.

Two molecules of ATP are required for the first stage of glycolysis, while 4 ATP molecules and 2 NADH molecules are formed in the second stage.

There is a population where the frequencies of allele 1 and allele 2 are 0.7 and 0.3, respectively. Allele 1 has a selection coe
Lorico [155]

Answer:

0.8

Explanation:

There is a population where the frequencies of allele 1 and allele 2 are 0.7 and 0.3, respectively

Let's use GG to represent allele 1

Let's use gg to represent allele 2

So we can equally say that;

GG = p = 0.7

gg = q  = 0.3   ( from Hardy-Weinberg Equilibrium)

So, given that the selection coefficient = 0.2

We known that the cross between GG and gg will definitely results to (GG,Gg and gg)

Then the fitness of these genes can be represented as:

1 - s, 1 and 1 - t respectively.

Thus. the allele 1's genotype fitness can be determined as

= 1 - s    ( where s is the selection coefficient)

= 1 - 0.2

= 0.8
