In one generation, the frequency of the A allele is 70 percent and the frequency of the a allele is 30 percent. What are the chances of an individual in the next generation having the genotype aa if the population is in genetic equilibrium? 49% 42% 30% 9%

Answers

Answer:

The correct answer would be 9%.

As the population is in genetic equilibrium, then the population must be following the Hardy-Weinberg equations:

p + q  = 1 and

p² + q² + 2pq = 1

The frequency of A (dominant allele) in a population is 70 percent.

Thus, the value of p would be 70/100 which comes out be 0.7

Similarly, the value of q would be equal to 0.3

The frequency of individual with homozygous recessive genotype, that is, aa would be equal to q².

So, q² = (0.3)^(2) ⇒ 0.09

Thus, the frequency of individual with genotype aa would be equal to 9 percent.

9%

Why?
The frequency for allele a is 30% or 0.3. Let's call this frequency p.
p^2 would then represent the frequency of genotype aa (this is is derived from the formula p^2+2pq+q^2=1 where p and q represent alleles a and A respectively. So p^2=aa, pq=Aa and q^2=AA)
0.3^2=0.09 or 9%

Which tool can be used to determine the volume of a metal bolt?

Answers

The answer is a graduated cylinder.

Graduated cylinders are used for volume measurement. To determine the volume of irregular shaped tool, such as a metal bolt, the displacement method is useful. Therefore, the graduated cylinder is filled with water. The metal bolt is then placed into the cylinder. It will displace the water, so the difference in the volume, before and after the bolt is placed, is actually the volume of the metal bolt.

An enzyme is a form of what?
a. DNA
b. glucose
c. protein
d. lipid

Answers

Answer: C. Protein

Explanation:

Enzymes are a type or form of proteins as they are also made up of amino acids, which are the building blocks of proteins. These amino acids will dictate how it will function.

Enzymes function to speed up chemical reactions within cells.

Classify the synthesis of a protein from amino acids as anabolic or catabolic . Explain

Answers

Protein synthesis is an anabolic reaction because these reactions build molecules while catabolic ones break them down. Thanks to this we know that protein synthesis is anabolic.

Protein synthesis is an anabolic reaction because these reactions build molecules while catabolic ones break them down. Thanks to this we know that protein synthesis is anabolic.

Explanation:

Anabolism relates to the process in cells where large macromolecules are formed up from miniature ones. In this case here, protein structure uses other proteins and amino acids (proteins' monomers) to make extra proteins, and so that is the accumulation of a large molecule, and accordingly studied anabolism.

Catabolism is the reverse of anabolism. An example would be the separation of proteins in food to amino acids for digestion. In this case, a large particle (a protein) is split down into miniature dispersible molecules (amino acids).

The scarlet cup fungus (Sarcoscypha coccinea) obtains its nutrition from decaying wood by releasing digestive enzymes into the wood and absorbing the digested products.I. Autotroph
II. Heterotroph
III. Saprotroph
A. III only
B. II and III only
C. I and III only
D. I, II and III

Answers

II and III only. The fungus is a heterotroph, since it's not making it's own food, but it's also a Saprotroph (since it externally digests dead organic materials; saprotrophs are a special subset of heterotrophs).
