A chemical family whose members exist as reactive diatomic molecules in the gaseous phase is the?

Carbohydrates are a type of biological macromolecules required to carry out life functions. Which of the following statements re

loris [4]

Given what we know, we can confirm that the correct option is D, which states that "They are used by living things as the main source of energy."

<h3>What are carbohydrates?</h3>

They are the primary source of energy for most cells.
They are what we refer to as sugars.
The main example of this is glucose.
They are formed by monomers called monosaccharides.

Therefore, we can confirm that since carbohydrates are what we refer to as sugars, which include molecules like glucose and this is the main source of energy for most cells, option D is the correct choice.

Two genes determining a trait In primroses, the dominant allele of gene K is necessary to synthesize blue flower pigment. Blue p

GREYUIT [131]

Answer:

The ratio of blue to white offspring in the progeny is 4 blue : 12 white.

Explanation:

Available data:

The dominant allele K is necessary to synthesize blue flower pigment
K is inhibited by the dominant allele D

Plants with the genotype K- D- will not produce pigment (and their flowers will be white)

Cross: testcross for (Kk Dd) plants

Parental) KkDd x kkdd

Gametes) KD kD Kd kd

kd kd kd kd

Punnet square) KD Kd kD kd

kd KkDd Kkdd kkDd kkdd

Whenever D is present, it inhibits the expression of the K gene, so every plant with the dominant D allele will be white. This plants´ genotype is kkD- or K-D-.

Whenever D is absent and K is present, every plant with genotype K-dd will be blue.

The recessive form for K and D genes will express white-flowered plants, with genotype ddkk

F1) Progeny genotype: 4/16 KkDd, white-flowered plants

4/16 Kkdd, blue-flowered plants

4/16 kkDd, white-flowered plants

4/16 kkdd, white-flowered plants

The ratio of blue to white offspring in the progeny is 4 blue : 12 white.

Blue-flowered plants: 4 Kkdd

White-flowered plants: 4 KkDd + 4 kkDd + 4 kkdd
