Exposing inner mitochondrial membranes to ultrasonic vibrations will disrupt the membranes. However, the fragments will reseal "

Leno4ka [110]

Answer:

Electron transport chain and ATP synthase

Explanation:

The inner mitochondrial membrane contains an electron transport chain and ATP synthesis. Four membrane protein complexes serve as the electron carriers and are embedded in the inner mitochondrial membrane. These protein complexes are called complex I, II, III and IV. Transfer of electrons from NADH and FADH2 to terminal electron acceptor oxygen occurs via these protein complexes.

During electron transfer, the pumping of protons towards the inner mitochondrial membrane creates an electrochemical gradient. The downhill transfer of protons back to the matrix via proton channel of ATP synthase drives phosphorylation of ADP. Therefore, presence of all the protein complexes of the electron transport chain and ATP synthase is required for electron transfer and ATP synthesis.

How does smoking and arterial plaques increase the risk of hypertension

Papessa [141]

Coronary heart disease (CHD) occurs if plaque builds up in the coronary (heart) arteries. ... Smoking is a major risk factor for heart disease. When combined with other risk factors—such as unhealthy blood cholesterol levels, high blood pressure, and overweight or obesity—smoking further raises the risk of heart disease.

In some breeds of mice, yellow coat color is

Elis [28]

In the exposed lethal genes cause the individual's death during embryionic development before being born. H0m0zyg0us dominant individuals do not get born. Yellow: 2/3. Grey: 1/3. Phenotypic ratio: 2:1

<h3>What is complete dominance?</h3>

When the dominant allele completely masks the expression recessive allele, we talk about complete dominance.

This is the case of individuals that are heter0zyg0us for a particular gene and express the dominant trait.

The dominant allele is hiding the expression of the recessive allele.

<h3>What are the lethal genes?</h3>

Refer to genes that impede the normal development of the individual.

They can cause death during embryo development before the individual gets born,

They can cause the individual's death after being born and before reaching sèxual maturity.

Let us assume that mice color is coded by a single diallelic gene that expresses complete dominance.

Available data:

Yellow color is dominant over grey color.

Yellow is coded by the dominant allele Y
Grey is coded by the recessive allele y

Genotype YY → Yellow and lethal

Genotype Yy → Yellow

Genotype yy → Grey

The cross would be as follows,

Cross: Yy x Yy

Gametes) Y y Y y

Punnett square) Y y

Y YY Yy

y Yy yy

F1) Considering ONLY the successfully born individuals

Genotype

2/3 = 50% of the progeny is expected to be heter0zyg0us, Yy.

1/3 = 25% of the progeny is expected to be h0m0zyg0us recessive, yy.

Phenotype

2/3 = 50% of the progeny is expected to be yellow, Yy.

1/3 = 25% of the progeny is expected to be grey, yy.

The phenotypic ratio is 2:1
