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

A scientist investigates two types of cells located in different parts in a human body. Cell A contains many more mitochondria t

Ket [755]

Answer: Cell A does more work than cell B.

Mitochondria is the energy producer organelle of the cell. It produces energy in the form of ATP molecules. It is a membrane bound organelle which is only present in eukaryotic cells not found in prokaryotic cells. Presence of more number of mitochondria in the cell indicates that the energy requirement of the cell is more. This energy is required for cellular metabolism. Therefore, cell with more mitochondria works more than the one with less mitochondria.
