If a population with two alleles is at Hardy-Weinberg equilibrium ad the frequency of one allele is 0.7, what is the heterozygot
Vinil7 [7]

Answer:

B. 0.42

Explanation:

Since the two alleles are at Hardy-Weinberg equilibrium, the sum of the frequency of two alleles will be one. If the frequency of a dominant allele is "p" and that of the recessive allele is "q", then p+q=1

According to the given information, the frequency of one allele in the population is= 0.7

This means that the frequency of the other allele would be= 1-0.7 = 0.3

Frequency of heterozygote in the population =2pq = 2 x 0.7 x 0.3 = 0.42

Alinara [238K]

Answer:

B) CO

Explanation:

Chemical decompsition or breakdown is defined as the process in which a substance can be broken down into simpler compounds through chemical means.

CO or carbon monoxide can be decomposed by chemical change because it can be broken down into into carbon and oxygen.

While Co (cobalt), Cr (chromium), and Cu (coppoer) are present in its simplest form and can not be decomposed further.

Hence, the correct answer is "B) CO".

One reason that atp is a source of energy is that the products of atp hydrolysis have less free energy
Svetlanka [38]
Correct! molecules going through reactions always want to form products that are less in energy so that molecules can be more stable. ATP molecule when made is not very stable and so it is high in energy. So when hydrolyzed, it breaks down to something simple and releases energy and achieves a less free energy (deltaG) state
