D. The Krebs cycle

Here’s the Explanation for it:

The Cellular respiration refers to the biochemical pathway in which the cells release energy from chemical bonds of food molecules. The energy that is provided is very important to the creation of life itself.

The aerobic phases of the cellular respiration in eukaryote is seen within mitochondria (organelles). This is know as the Krebs Cycle and the electron transport chain which are aerobic phases.

Natalka [10]

Answer:

D. Adrenaline

Explanation:

Adrenaline hormone is secreted by adrenal medulla during stressful conditions. The hormone is involved in preparing the body for stressful conditions by intensifying the sympathetic response.

If a person is chased by a dog, the adrenaline hormone is released from the adrenal medulla. The hormone triggers the preganglionic neurons of the sympathetic division of the autonomous nerve system to generate the flight or flight response.

Adrenaline increases the heart rate, blood pressure, and blood flow to skeletal muscles and adipose tissues. The hormone also triggers the dilation of airways and increases the blood levels of glucose and fatty acids.

In cucumbers, dull fruit (D) is dominant over glossy (d) fruit, orange friut (R) is dominant over cream fruit (r), and bitter co

stiv31 [10]

Explanation:

Dull fruit (D) is dominant over glossy (d) fruit.
Orange friut (R) is dominant over cream fruit (r).
Bitter cotyledon (B) is dominant over non-bitter cotyledons (b).

The three genes are independent.

A plant homozygous for dull, orange fruit and bitter cotyledons has the genotype <em>DDRRBB</em><em>.</em>
A plant homozygous for glossy, cream fruit and non-bitter cotyledons has the genotype <em>ddrrbb</em>.

100% of the F1 will have dull, orange fruit and bitter cotyledons and will be heterozygous for all genes: <em>DdRrBb</em>.

<u>The F2 will have 8 possible phenotypes:</u>

27 D_R_B dull, orange fruit and bitter cotyledons
9 D_R_bb dull, orange fruit and non-bitter cotyledons
9 D_rrB_ dull, cream fruit and bitter cotyledons
3 D_rrbb dull, cream fruit and non-bitter cotyledons
9 ddR_B_ glossy, orange fruit and bitter cotyledons
3 ddR_bb glossy, orange fruit and non-bitter cotyledons
3 ddrrB_ glossy, cream fruit and bitter cotyledons
1 ddrrbb glossy, cream fruit and non-bitter cotyledons

An F1 plant is crossed with a plant that has glossy, cream fruit and non-bitter cotyledons.

<h3>DdRrBb x ddrrbb </h3>

The F1 individual can produce 8 types of gametes: DRB, DRb, DrB, Drb, dRB, dRb, drB and drb. The cream fruit and non-bitter cotyledons individual can only produce drb gametes. This cross also produces a progeny with the following genotypes and phenotypic proportions:

8 DdRrBb dull, orange fruit and bitter cotyledons
8 DdRrbb dull, orange fruit and non-bitter cotyledons
8 DdrrBb dull, cream fruit and bitter cotyledons
8 Ddrrbb dull, cream fruit and non-bitter cotyledons
8 ddRrBb glossy, orange fruit and bitter cotyledons
8 ddRrbb glossy, orange fruit and non-bitter cotyledons
8 ddrrBb glossy, cream fruit and bitter cotyledons
8 ddrrbb glossy, cream fruit and non-bitter cotyledons

5. Characteristics such as a widow's peak or attached earlobes are determined by

Troyanec [42]

Answer:

Explanation:

The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.
