A mistake happens during mitosis g where all of the mitochondria are pulled to one pole of the cell and none are pulled to the o
LuckyWell [14K]

Answer: Daughter cell that does not receive mitochondria, will not be able to produce the energy needed to carry out cell functions. The cell that receives all the mitochondria, will be able to carry out cellular respiration and thus produce energy.

Explanation:

The mitochondrion is a cellular organelle found in eukaryotic cells, and provides the energy needed to carry out cellular activity. They are characterized by their large size, compared to other cell organelles, and their globular shape. <u>Mitochondria generate most of the chemical energy needed to activate the biochemical reactions in the cell</u>,<u> through a process called cellular respiration</u>. It irefers to a set of biochemical reactions by which certain organic compounds are degraded by oxidation into inorganic substances. The chemical energy produced by mitochondria is stored in an energized molecule called adenosine triphosphate (ATP).

Then, if during cell division, one of the daughter cells does not receive mitochondria, it will not have the necessary organelles to carry out cell respiration and will not be able to produce the energy needed to carry out cell functions. The cell that receives all the mitochondria will have no major problems, it will be able to carry out cellular respiration and thus produce energy.

Which of the following is a reasonable explanation for why unsaturated fatty acids help keep any membrane more fluid at lower te
vladimir1956 [14]

Answer:

Option (E).

Explanation:

The cell membrane constitute the phospholipid bilayer, proteins and small amounts of carbohydrates. The unsaturated fatty acids contain the double and triple bond in its structure.

The introduction of double bond introduces the kink in its structure and makes the membrane less rigid. This prevents the packaging of the lipid tightly and makes the membrane more permeable. This makes the membrane more fluid even at the lower temperature.

Thus, the correct answer is option (E).
