A geneticist analyzes the four products of a meiosis for an Aa Bb plant and finds that two of the products have the AB alleles a

slega [8]

Answer:

No, this is not consistent with the principle of independent assortment.

Explanation:

The principle of independent assortment states that alleles from different genes assort independently. This means that if a plant has a genotype Aa Bb, all four alleles (A, a, B, and b) are going to segregate equally, so we will have the following four gametes after meiosis:

- AB

- Ab

- aB

- ab

If the researcher finds that two of the four products are AB, probably there would be a deviation of Mendel's laws.

seropon [69]

During glycolysis, the source of the chemical energy that is captured in ATP:

B. the chemical bonds in glucose

Explanation:

Glycolysis is also known as Embden-meyerhof pathway.
It is an oxidative process in which one mole of glucose is partially oxidized into two moles of pyruvate.
Glycolysis occurs in the cytosol of the cell in both aerobic and anaerobic conditions.
The breakdown of six-carbon glucose into two molecules the three-carbon pyruvate occurs in ten steps.
The first five steps of this pathway constitute the preparatory phase.This phase consumes energy during the phosphorylation of glucose.
The preparatory phase produces two molecules of glyceraldehyde 3-phosphate (G3P).
The two molecules of G3P are then converted to pyruvate in the next five steps that constitute the payoff phase.

The energy gain of glycolysis comes in this payoff phase.
The oxidation of G3P yields a high energy molegule 1,3 -bisphosphoglycerate .
The high energy phosphate on carbon 1 of this molecule is donated to ADP and ATP is produced.
This synthesis of ATP is called substrate level phosphorylation because ADP phosphorylation is coupled with exergonic breakdown of a high-energy bond.

Read the following passage and construct a flow chart by matching the following events with their proper sequence. Physical exer

blsea [12.9K]

Answer:

Person starts to exercise.

Skeletal muscle oxygen demand increase

Skeletal muscle metabolism increases

.Blood delivery to the skeletal muscle increases is order to provide more oxygen

Oxygen sensors cause local blood cell vessels to dilate

This steps briefly describe the physiology of exercise.

At the onset of exercise, skeletal muscles cells were sustained with available oxygen from the Myoglobin. Myoglobin is oxygen binding and storage protein found in cardiac and skeletal muscles cells. it has high storing capacity for oxygen.

However as the exercise becomes intense ATPs supply drops, oxygen demand increases,cellular metabolisms demand also increase to supply glucose and ATP to the cells.

The liver mediates Gluconeogenesis. Fatty acid is broken down to glucose for cellular respiration with' ketone bodies build up..Exercise also stimulates the breakdown of muscle glycogen to glucose, Therefore, cellular respiration takes place to break down the glucose to C02, H20 and energy with rise in temperature.

However, oxygen concentration is low, therefore muscles cells undergo anaerobic respiration with lactic acid pathway. Lactic acid build up in muscles cells.The muscles cells under go oxygen debt to break down lactic acid to glucose in muscle.

Therefore to adjust the mechanism oxygen homeostatic sensors increases hyperventilation to increase oxygen intake through the lungs, and vasodilation. so that maximum volume of blood containing oxygen is transported to muscles cells; to sustain the intense activity
