Why Is Meiosis I Referred To As The Reduction Division? (2023)

Health High School


Answer 1


Meiosis 1 reduces the number of chromosomes


In somatic cells (the cells in our body that are not sex cells) there is only mitosis, which involves duplicating the genetic material and then dividing in two, to produce two identical, daughter cells.

In germ-line cells (the cells that become sex cells), there is both mitosis and meiosis. Mitosis occurs as normal to produce more germ-line cells, while meiosis forms gametes (with a haploid number of chromosomes).

Meiosis 1 is referred to as the reduction division because, in mitosis, the chromosomes are duplicated and then the cell divides, however, in meiosis 1 the cell simple splits itself without duplicating the chromosomes, so there is only one set of chromosomes instead of the normal two sets.

Answer 2

because it reduces the number of chromosomes from 46 chromosomes or 2n to 23 chromosomes or n (n describes a single chromosome set).

Describe what oxidative stress is. Provide three examples of how our bodies can be exposed to oxidative stress. Also, describe the role antioxidants play in regard to oxidative stress. Be sure to include in your answer a brief explanation of what free radicals are.


Oxidative stress is an imbalance between the production of free radicals (highly unstable molecules that are naturally formed when you exercise and when your body converts food into energy) and the ability of the body to counteract or detoxify their harmful effects through neutralization by antioxidants. Antioxidants such as thiols or ascorbic acid prevent free radicals forming due to oxidation. Some ways our bodies can be exposed to oxidative stress are by having an unbalanced diet, smoking, or sun exposure. Some ways to prevent oxidative stress are having a healthy diet, not smoking, exercising regularly and wearing sunscreen.

Which type of health insurance provider generally does not allow patients to obtain services outside its perferred network of doctors and specialists A: traditional B: preferred provider organization C: point of service plan D: health maintenance organization



B: preferred provider organization


A preferred provider organization, or PPO, is a type of managed health care organization that is often offered as part of health insurance coverage in the United States. The basic concept of this approach is to offer members of the insurance plan access to highly qualified medical professionals who have also agreed to take care of all plan members at reduced prices. While the exact structure of the PPO will vary somewhat from one provider to another, most plans of this type provide greater benefits if the member uses the doctors and health centers that are part of the network. A reduced benefit is often available if the member uses a doctor or facility that is not considered part of the network.

A point in the service plan that is structured as a preferred provider organization is available in multiple configurations. Group insurance plans offered through employers and other types of organizations often use this model. People who wish to secure personal health insurance coverage also often offer this type of plan. Many people prefer this approach because it provides the ability to choose and choose their health care providers from the list of doctors provided by the insurance provider. This is in contrast to most HMO or health maintenance organizations, where plan administrators assign the member to a primary care physician.

Answer: B

B. Not enough breaks and an inadequate child-to-staff ratio
C. Too many children in one room
D. Inadequate compensation and lack of benefits for workers


The correct options are

A. Professional disagreements and fluctuating hours

D. Inadequate compensation and lack of benefits for workers


Employee turnover refers to the number or percentage of workers who leave an organization and are replaced by new employees. Keeping employee turnover low helps a company maintain productivity. If the staff is unprofessional and the managers are unable to cooperate with them in terms of working hours, it is obvious that disagreements will occur. In the same way if the managers do not provide sufficient incentives and benefits to good employees, the workers will likely leave the organization in search of a good opportunity somewhere else.

Employee turnover is expensive. While some turnover can be expected, poor management can cause the normal turnover to climb to an excessive level. According to the U.S. Bureau of Labor Statistics, turnover can cost an organization 33 percent of an employee's total compensation, including wages and benefits.
