7 0

Answer:

When the pollen tube grows into the ovule

Explanation:

Simmilar to animals, fertilization occurs when the egg (ovule) and the sperm join together to produce a new individual. In flowers, when the pollen tube grows into the ovlue is when pollen and ovule join together and fertilization occurs. A new seed is the produced, ready to produce a new individual.

let A and a represent dominant and recessive alleles whos respective frequencies are p and q in a given interbreeding population
lesantik [10]

Answer:

A) 48 %

B) 18 %

Explanation:

A) Given

Frequency of individuals in the population having recessive phenotypes = 16%

Frequency of individuals in the population having recessive phenotypes is represented by q^2

q^ 2 = 0.16\\q= \sqrt{0.16}\\ q = 0.4

Thus frequency of recessive genes is equal to 40%

frequency of dominant genes is equal to

p = 1-q\\= 1-0.4\\= 0.6

Now,

p^2 + q^2+2pq = 1\\2pq = 1-0.16-0.36\\2pq = 0.48

48 % of genes exist in the heterozygous condition

B.

Frequency of individuals in the population having recessive phenotypes = 1%

Frequency of individuals in the population having recessive phenotypes is represented by q^2

q^ 2 = 0.01\\q= \sqrt{0.01}\\ q = 0.1

Thus frequency of recessive genes is equal to 10%

frequency of dominant genes is equal to

p = 1-q\\= 1-0.1\\= 0.9

Now,

p^2 + q^2+2pq = 1\\2pq = 1-0.01-0.81\\2pq = 0.18

18 % of genes exist in the heterozygous condition

Which statement correctly distinguishes the roles of protein kinases and protein phosphatases in signal transduction pathways?
vesna_86 [32]

Answer:

A) Protein kinases activate enzymes by phosphorylating or adding phosphate groups to them. Protein phosphatases dephosphorylate or remove phosphate groups from enzymes, including protein kinases.

Explanation:

Protein kinases are enzymes that have the ability to modulate other enzymes (or some other proteins) by adding the phosphate group. This is known as phosphorilation process. As a result of structural change, protein can change its activity (phosphorilation usually increase the activity).

Phosphatases are enzymes with opposite function, they remove phosphate group from the protein causing different effect.
