Answer:

There are ethical or privacy concerns to consider.

Explanation:

Human subject research is a systematic, scientific investigation that can be either interventional, a trial research or observational (test).

It is necessary to follow the Nuremberg code (1948) and have a voluntary informed consent, the research should be based on previous good results, on prior research, physical or psychological injury and harm should be avoided, benefits should outweigh risks, proper experience of a researcher is needed, right to withdraw consent, and research must stop if harm is arising.

In 1964, a guideline for medical doctors in biomedical research has been established by WMA (The World Medical Association). Helsinki declaration stated the ethical principles involving human subjects that was adopted.

In, 1982  International Ethical Guidelines for Biomedical Research Involving Human Subjects by the World Health Organization (WHO) and Council for International Organizations of Medical Sciences (CIOMS) has been established.  

According to Guidelines (2002) ethical justification and scientific validity of research, ethical review, informed consent, vulnerability ¬ of individuals, groups, communities and populations, women as research subjects, equity regarding burdens and benefits, choice of control in clinical trials, confidentiality, compensation for injury, strengthening of national or local capacity for ethical review, and obligations of sponsors to provide health-care services are outlined.

There are 4 most important principles of ethics such as autonomy, beneficence, non-malfeasance and justice.

Ethical Review Board (ERB) is a committee that has been formally designated to approve, monitor, and review biomedical and behavioural research involving humans. It aims to protect the rights and welfare of the research subjects.  The ERB must have at least five members. The members must have enough experience, expertise, and diversity. If the ERB works with studies that include vulnerable populations, the ERB should have members who are familiar with these groups. The ERB must include at least one person who is not affiliated with the institution or in the immediate family of a person affiliated with the institution.  ERB members may not vote on their projects. The ERB may include consultants in their discussions to meet requirements for expertise or diversity, but only actual ERB members may vote.

If mitosis stopped in your body, what effects would you see most rapidly? Which tissues would
kogti [31]

Cell division during mitosis is necessary for replacing damaged or dying cells, as well as repairing damaged or worn-out cells that occur naturally. The main mechanism behind growth is this kind of cell division.

<h3>What are the consequences if mitosis stopped in the body?</h3>

Without mitosis, there wouldn't be any cell division or growth. The fact that genetic information cannot be passed on is most essential. All cell processes would be significantly impacted.

You might also suffer serious consequences, as your heart would have to beat by itself, among other things. Your bones or your brain wouldn't be immediately impacted, but your blood cells would.

Therefore, Every cell in your body would stop replicating itself if mitosis halted, which would induce a heart attack.

Roman55 [17]

The polarity of water enables it to serve as a solvent for polar substances.

A polar substance is a substance that has a positive end and a negative end. Water itself is a polar substance and this polarity enables it to dissolve polar substances.

For instance, HCl dissolves in water because it is polar. The positive end of the dipole in HCl attaches to the negative end of the dipole in water and the negative end of the dipole in HCl attaches to the positive end of the dipole in water.

This dipole - dipole interaction accounts for the dissolution of HCl in water.

Also, ion - dipole interaction accounts for the dissolution of ionic substances such as NaCl in water.
