Which statement correctly uses the model above to explain how mitosis maintains genetic continuity? A. The chromosomes in cell 1 are the same as in cells 6.B. Crossing-over occurs in cell 4. which increases genetic diversity in cells 6.
C. When the nuclear membrane reforms in cell 5. each nucleus becomes diploid in number. Option 3
D. The independent assortment that is represented in cell 2 ensures that cell 3 has the correct number of
chromosomes.
Which statement correctly uses the model above to explain how - 1

Answers

Answer 1
Answer:

The statement that correctly uses the model to explain how mitosis maintains genetic continuity would be that the chromosomes in cell 1 are the same as those in cell 6. The correct option would be A.

Mitosis refers to the division of vegetative cell. When a cell divides by mitosis, the daughter cells produced have the same genetic components as the original cell. Hence, the daughter cells continue carrying the genetic components as the parent cell.

In the model, cell 1 is the one dividing and the daughter cells are the two cells in 6. The cell in 1 and those in 6, therefore, must have the same chromosomes in order for genetic continuity to be maintained through mitosis.

Which of the following is not a benefit of biofilms for bacteria?O a
Ob
oc
Od
Biofilms allow for adhesion of colonies
Bacteria can share nutrients
Allows for resistance to sanitation
Better spreading of reproductive cells

Answers

Answer:

Better spreading of reproductive cell is not a benefit of bioflims for bacteria.

Option: (d)

Explanation:

  • Bioflims can allow for adhesion of colonies, that can attach surface such  as rock, tooth and it includes single or group of micro organism.
  • Bioflim bacteria can share 'nutrients' and it is  sheltered from 'harmful factors' in environment like desiccation, antibiotics, etc.
  • It allow resistance for sanitation, that hold bacteria together and also exclude most disinfectant and antibiotics. It is resistant to sterilization.

What does the nuclear membrane do?

Answers

A nuclear membrane is a bilayer membrane that encloses a nucleus in eukaryotic cells and thus surrounds the genetic material of the cell. It consists of two phospholipid bilayers with many small holes. Those holes allow different material, such as proteins, RNA, ATP, water, to move in and out of the nucleus. Therefore its function is to regulate the flow of RNA and proteins since DNA, which carries the genetic information of the cell, cannot leave the nucleus.

What aquatic species is the least susceptible to acid rain? (Refer to the chart in the lesson to answer this question.)trout
mayflies
frogs
bass

Answers

Answer:

frogs

Explanation:

Among the organisms shown in the question above, frogs are the least susceptible to damage caused by acid rain, but that does not mean that frogs do not suffer any damage, quite the contrary. Frogs are amphibians and like all amphibians have very sensitive and highly permeable skin, which makes acid rain very harmful to your body and can cause fatal consequences.

Least susceptible is mayflies

. A person rides his bicycle several miles. What process is used by the cells in his legs to release energy at the beginning of the ride and at the end what cause the pain in his legs

Answers

Answer:

At the beginning, aerobic respiration is used by his legs to generate energy when there was still sufficient oxygen intake for energy to be generated via oxidative phosphorylation.

Towards the end of the ride, his legs are generating energy through anaerobic respiration due to insufficient oxygen intake to keep up with the energy requirement of his muscles as he cycles continuously. Through anaerobic respiration, pyruvate from glycolysis is converted to lactate by lactate dehydrogenase instead of being channelled to the mitochondria for oxidative phosphorylation. The accumulation of lactate in his muscles is what causes the pain in his leg. After he stops the activity, the pain would reduce as lactate is transported to the liver to be reconverted back into pyruvate.
