What is the differences between mitosis and meiosis and explain why there is meiosis 1 and 2 in cell division but this is not happening with mitosis

Answers

Answer 1
Answer:

Answer:

Explanation:

Cells divide and reproduce in two ways, mitosis and meiosis.

Mitosis results in two identical daughter cells, whereas meiosis results in four cells.

Keys differences and similarities between the two types of cell division.

                                             Mitosis                  Meiosis

cells created:          two daughter cells      four daughter cells                                                          

Ploidy Creates diploid daughter cells Creates haploid daughter cells

Genetics  Daughter cells are                 Daughter cells are  .                                                                                 .                      genetically identical                  genetically different

Why is there a meiosis II but not mitosis II?

Meiosis II is generally regarded as being very similar to mitosis, except for the presence of two parent cells, instead of only one. In both meiosis I and II, cytokinesis occurs, and there are two daughter cells per parent cell.

The correct answer to the question above is (c.) natural selection. The natural selection is the process in which individual with useful traits are more likely to survive and produce more offspring with those useful traits. 
c is the correct answer

1. Before the introduction of the yellow crazy ant to Christmas Island, land crabs ate many plant seedlings in the forest, maintaining a relatively clear forest floor. As the crab population has declined, plant seedlings have flourished. The forest floor is now covered with plants. Choose the statement that best describes what is occurring on the forest floor. A. Primary succession is occurring because the ant is a new species changing the ecosystem.
B. Secondary succession is occurring because the organisms on the forest floor are changing.
C. Climax vegetation is occurring because the seedlings finally have the chance to grow.
D. Primary succession is occurring because more plant life is healthier for the ecosystem.

Answers

the statement that best describes what is occurring on the forest floor is that secondary succession is occurring because the organisms on the forest floor are changing. The answer to your question is B. I hope that this is the answer that you were looking for and it has helped you.

Answer:

B. Secondary succession is occurring because the organisms on the forest floor are changing.

What is scientific consensus

Answers

The opinion of scientists in a particular field with majority of them supporting a concept, belief or a suitability of a question lead to scientific consensus. The consensus may or may not be proved true  at the end of the research but at their primary level they gain maximum support as they are based on some evidence or observation. Overall scientific consensus can be stated as convergence of high quality evidences leading to same conclusions.
Scientific consensus is the collective judgment, position, and opinion of the community of scientists in a particular field of study. Consensus implies general agreement, though not necessarily unanimity.
