Tamiku [17]

Answer:

A. I only

Explanation:

Exotic animal species are really found in most countries and given that people these animals, they are very valuable. Species like lions, tigers, parrots, cheaters and even pythons are loved for exotic nature.

For this reason, they are caught, killed, shipped and sold in various countries or regions like dubia, Saudi Arabia etc. Its effects on the population of these species are disastrous.

If the inspection of goods coming into a country is intense and frequent, it will mitigate the shipping and sales of the species.

Lunna [17]

Answer:

1. Aorta

2. Left atrium

3. Right ventricle

4. The pulmonary artery

5. Left ventricle.

Explanation:

The aorta is the main artery of the body that carries the oxygen-rich blood to all the body parts except the lungs from the left ventricle. It is divided into main coronary arteries or blood vessels.

The left atrium is one of the heart chambers, it is located in the upper part of the heart on the right side that receives the oxygenated blood from the lungs through the pulmonary vein.

The right ventricle is the chamber of the heart that pumps the deoxygenated blood to the pulmonary valve to MPA to the lungs to get oxygenated.

The pulmonary artery or the main PA (MPA) carries the oxygen-depleted blood from the right ventricle into the lungs, where blood becomes oxygenated.

The Left ventricle is the thickest muscle chamber of the heart responsible for the pumping oxygen-rich blood to the circulatory system and to the body through the aorta.

Given the parents AABBCc × AabbCc, assume simple dominance for each trait and independent assortment. What proportion of the pro
Anit [1.1K]

Answer:

3/4

Explanation:

If we assume simple dominance and independent assortment for each trait, we can use Mendel's Law of Segregation to predict the phenotypic proportions in the offspring of the parental cross AABBCc x AabbCc.

<h3><u>Gene A</u></h3>

AA x Aa

  • F1 genotypes: 1/2 AA, 1/2 Aa
  • F1 phenotypes: all A
<h3 /><h3><u>Gene B</u></h3>

BB x bb

  • F1 genotypes: 1 Bb
  • F1 phenotypes: all B
<h3 /><h3><u>Gene C</u></h3>

Cc x Cc

  • F1 genotypes:  1/4 CC, 2/4 Cc, 1/4 cc
  • F1 phenotypes: 3/4 C, 1/4 cc

We want to know the proportion of progeny with all dominant phenotype (A_B_C_). Since the genes are independent, we can multiply the probabilities of each gene to obtain the overall probability of having a ABC progeny:

<h3>1 A_ x 1 B_ x 3/4 C_ = 3/4 A_B_C_</h3>
