The greatest amount of genetic variation is produced in offspring that reproduce -
A. sexually through fission B. asexually through budding C. sexually through meiosis D. asexually through mitosis

Answers

In meiosis, the greatest amount of genetic variation is produced in offspring that reproduce sexually, hence option C is correct.

How do organisms reproduce sexually through meiosis?

Because the environment is continually changing, sexual reproduction often has an advantage over asexual reproduction.

Increased phenotypic variation, or the physical variety of the organisms, results from higher genetic diversity.

Each gamete has a unique DNA set because of recombination and independent assortment during meiosis. The resultant zygote has a special set of genes as a result.

Genetic variety can be increased by new genes and alleles being created as a result of gene duplication, mutation, or other events.

Therefore, it is possible for novel gene combinations to arise during sexual reproduction.

how would this affect the cells made from the cell cycle? passage: timmy has a disease that effects his cell cycle, it causes the S phase (part of interphase) to not work correctly.

Answers

Answer:

No cells are produced.

Explanation:

If the S phase of cell cycle did not work properly, the cells produced are abnormal or no cells are produced because no extra copy of chromosomes are present for cell division. If there is no extra copy of chromosomes is present in the cell, the cell will not go to the G2 phase and as a result the cell cycle is remain incomplete. So that's why we can say that no cells are produced if S phase did not work properly.

Explanation:

Condensation is a process in which water that is present in the vapors form changed into liquid state. Condensation greatly affect Earth systems because this process is responsible for the precipitation on the earth. Condensation occurs in the atmosphere when warm air rises in the atmosphere, cools and unable to hold water vapor. As a result, water vapors condenses to form cloud droplets that falls in the form of rainfall.

An example that shows how organisms are dependent on each other would using a food chain as an example.
• mouse eat grass and drink water ( which is nonliving)
• mouse gets eaten by fox
• then fox then eaten by coyote and the cycle continues
However is one of these organisms have low population it will be difficult for the others. For example if there is a low population of coyotes then the fox population over populate same goes for if fox are low in population then the mouses become over populated hence diseases could spread from the mouses.
