When conducting an experiment, the control group does not receive the treatment, while the experimental group is exposed to it. Individuals from both groups come from the same population.
<h3>What are the control group and the experimental group?</h3>
During an experiment the researcher compares at least two groups: a control group and an experimental group.
Both of them are composed of individuals coming from the same population, so they are identical in all aspects except for the independent variables.
Both groups must be similar in every variable that might influence the results, except for the study treatment.
- The control group is the one used to identify any other factors influencing the results obtained in the study, apart from the modified variables of the treatment.
It is useful to have a control group to observe how it responds when no treatment is applied.
The independent variable always keeps constant in the control group.
- The experimental group is subjected to the effects of the treatment.
The researcher applies different treatments to the experimental groups to analyze their response.
The researcher voluntarily changes the values of the independent variable to observe how it affects the individuals subjected.
There can be several experimental groups.
In conclusion, the control group does not receive the treatment, while the experimental group does.

Answer: Option A - Gene A and C are potential oncogenes
Explanation:
Oncogenes are genes that contribute to the conversion of a normal cell into a cancerous cell when mutated or expressed at high levels.
From the information provided:
Gene A S24F, N465T R33T T345S, G366R P367E, P368Y and
Gene C S24F, I322E C255I, E344D S34E, P367E
Both gene A and C have two similar sequences which represent potential sites of mutation
A woman standing and watching the stars on a cool, calm night will lose most of her body heat by radiation. so correct option is A
The emission or transmission of energy as waves or particles across space or a material medium is known as radiation. Thermal radiation will cause the majority of the woman's heat to escape from her body. Evaporation is not a actual process because evaporation is a cooling process rather than a means of heat transfer since latent heat is lost during the process There will be little convection and conduction in this situation.

Answer:
The Respiratory system allows the entry of oxygen into the body and releases Carbon Dioxide. The Oxygen travels across lung tissue into blood vessels and the blood carries the oxygen around the body. Thus the Respiratory and Circulatory systems work together in gas exchange which is vital in Homeostasis.
Answer:
Bacteria cells have no nucleus.
