Please help, these questions on my hw are confusing to me.

Answers

Answer 1

10. before replication begins, the strands of DNA are separated and used as templates for the new strands. the replication process creates 2 identical double helixes, each has 1 new strand and 1 old one.

11. without dna replication, damaged cells could not be replaced/repaired and cells need dna, cells would become mutated without dna replication.

12. mutations are rare because dna polymerase proofreads the strands but if the process occurred incorrectly and was not corrected by the polymerase, the cell would become mutated and could be really harmful.

hope this helped!

Answer 2

11.) each of the newly replicated helics is formed from a semi-conservative parent strand and one daughter strand

12.) because it creates the next copy of DNA that have to into one of the two daughter cells when a cell divides. Without it each cell lacks enough hereditary fabric to give instructions for crating proteins vital for bodily purposes.

13.) proteins might not function normally or at all. They can cause mutations like disorders or cancer.

Answers

are you a draco stan?

The sun’s energy is like food for most plants like sunflowers, which is how they grow and survive. Herbivores( animals who eat plants and not meat ) eat these plants for their survival, which is how they grow and survive. Finally, when herbivores die, decomposers ( animals who eat dead or rotten things ) start to eat away at their dead bodies. This is how their life cycle goes.

Why is growth and reproduction of a cell cycle?

Answers

Answer:

In addition, a larger cell is less efficient in moving nutrients and waste materials across the cell membrane. - Asexual reproduction is the production of genetically identical offspring from a single parent. During the cell cycle, a cell grows, prepares for division, and divides to form two daughter cells.

Which phase of mitosis is shown in the diagram?
O anaphase
O metaphase
O telophase
O prophase

Answers

The phase of mitosis in the diagram is Anaphase.

The cell cycle can be divided into interphase and mitotic M phase.

The mitotic M phase refers to the process cell division of somatic cells.

This phase (M phase) can be divided into a series of sequential steps that include Prophase, Metaphase, Anaphase, Telophase and Cytokinesis.

In Anaphase, the chromosomes separate and travel to opposite poles of the cell.

In conclusion, the phase of mitosis in the diagram is Anaphase.
