Answer:

hello your question is poorly written attached below is the complete question

answer :

Hemoglobin  + oxygen  ⇄   oxyhemoglobin

[tex]Hb_{4}(aq) + 4O_{2}[/tex]   ⇄ [tex]Hb_{4}O_{8}[/tex]

Explanation:

The series of equation to represent the equilibria described in the prelab discussion can be written as :

Hemoglobin  + oxygen  ⇄   oxyhemoglobin

How does aerobic respiration differ from anaerobic respiration ?
I need long answer, and correctly explained.​

Answers

Answer:The difference between aerobic and anaerobic respiration.

Aerobic respiration  Anaerobic respiration

1. Aerobic respiration refers to complete breakdown of metabolic fuels in presence of oxygen. 1. Anaerobic respiration is the process of partial breakdown of fuel (glucose) in absence of oxygen.

2. It includes glycolysis, citric acid cycle and oxidative phosphorylation. The first two processes take place in the cytoplasm while last one occurs in mitochondria. 2. Glycolysis is followed by ethanol fermentation (occurs in yeast) or lactic acid fermentation (in muscles and microbes like lactic acid bacteria).  

3. The end products are carbon dioxide and water. 3. End products of ethanol fermentation are ethanol and carbon dioxide; that of lactic acid fermentation are lactic acid

4. Owing to complete oxidation of glucose, a large amount of energy is produced (36-38 ATP molecules) 4. Incomplete oxidation of glucose does not release all stored energy and only 2 ATP molecules are produced.

Anaerobic respiration is carried out by yeast and other anaerobic organisms like lactic acid bacteria, E. coli, Staphylococcus, Clostridium etc.

Explanation:

EVOLUTION CONNECTION The result of mitosis is that the daughter cells end up with the same number of chromosomes that the parent cell had. Another potential way to maintain the number of chromosomes would be to carry out cell division first and then duplicate the chromosomes in each daughter cell. Do you think this would be an equally good way of organizing the cell cycle

Answers

Answer:

No, because it would lead to chromosome mosaicism  

Explanation:

Chromosomal mosaicism can be defined as the presence of two or more cell populations with a distinct number and/or type of chromosomes in the cells of an organism. If the cell would split before chromosome duplication, it would lead to the fact that some cells would have one chromosome of the homologous pair being duplicated, while other cells would have duplicated the other one. In consequence, this process would produce a genomic imbalance between different cell populations that would be expected to be lethal for the organism.

Oxygen-rich blood is carried through pulmonary arteries from the lungs to the heart?

Answers

Yes,oxygen-rich blood is carried through pulmonary arteries from the lungs to the heart.

It is false that oxygen-rich blood is carried through pulmonary arteries from the lungs to the heart.

What is pulmonary artery?

The two principal arteries leaving the right ventricle of the heart are known as the pulmonary arteries. Low-oxygen blood is seen in this lower chamber of the heart. This blood travels to the lungs through the pulmonary arteries.

The middle mediastinum contains the main pulmonary artery, as well as the pulmonary arteries that follow on the right and left. They emerge from the four chambered heart's right ventricle and carry blood to the lungs.

Right side of heart sends deoxygenated blood to pulmonary artery. Nature has made it such that this blood reaches the lungs where carbon dioxide can be released and then oxygen can be loaded.

It is true that all arteries convey oxygenated blood, with the exception of the pulmonary artery.

Thus, the given statement is false.

hope this helped

Answer:

D) All of the above.

Explanation:

The Shape of a solid does not change (with exceptions), and the atoms typically remain static with little freedom of movement.

The volume of the solid also stays exactly the same if no external adjustments are made.

The arrangements of atoms & molecules are definitive and packed together, giving little movement, therefore allowing the solid to keep form.
