<span>
Viruses have the ability to reproduce on their own and sometimes within hosts. It is an infectious agent that can affect all types of life forms (e.g. animals, plants, microorganisms). They are found in almost every ecosystem on Earth and they are the most abundant type of biological identity.  Asvirology is the study of viruses which is a sub-specialty of microbiology. The spread in many ways and can be transmitted from one organism to another or sometimes to multiple organisms at the same time. Its origins in the evolutionary history of life is still unclear but they are considered to be life forms because of their capacity to carry genetic material, reproduce, and evolve through natural selection. </span>

Answer:

3: body temperature, fluid balance, blood pH, and oxygen tension within rather narrow limits, while at the same time obtaining nutrition to provide the energy to maintain homeostasis.

4: energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed.

5: Forms of energy include mechanical, chemical, electrical, nuclear, thermal, electromagnetic, and sound energy. These forms of energy can occur as either kinetic or potential energy.

6: Batteries and thermal energy

Bacteria have been found to be able to detoxify certain chemicals; perhaps there are more.

<h3>What is bacteria?</h3>

Bacteria are common, primarily free-living creatures with only occasionally one biological cell. Bacterium is the singular form. They account for a large chunk of the prokaryotic microbial kingdom. The bulk of the ecosystems on Earth are home to bacteria, which are typically a few micrometers long and were among the first life forms to emerge there.

Bacteria can be found in soil, water, acidic hot springs, radioactive waste, and the deep biosphere of the Earth's crust. Bacteria play a crucial role in several stages of the nutrition cycle by recycling nutrients like nitrogen from the atmosphere. The nutrient cycle includes the breakdown of dead bodies; microorganisms are in charge of the putrefaction stage of this process.

When doing medical research with human subjects,which four limitaions are unavoidable
Illusion [34]

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.
