If a scientist is conducting an experiment about obesity and asks a group of people to stop eating saturated fat, that group of people is called the experimental group. Thus, the correct option is A.
<h3>
Define experimental group in scientific study?</h3>
A experimental group in scientific study is defined as the researcher compares at least two groups during an experiment, a control group and an experimental group.
Because they are both made up of people from the same population, they are identical in every way except for the independent variables.
The therapy is administered to the experimental group. The researcher willingly alters the independent variable's values to see how it impacts the people who are being studied. Several experimental groups are possible.

For this you are going to use S as the dominate and r for the recessive. Since both of the parents are squared eye the offspring's likely chance of having round eyes will be 0%.
Answer is A. A population becomes separated by environmental factors into two groups that do not reproduce with one another.
When a population of a species become geographically separated then gene flow between them stops. Over a period of time, the population may become genetically different in response to the natural selection due to different environments. Selection and genetic drift will act differently on these two separated populations. This will results into two separate species. This type of speciation is called allopatric speciation.
Answer:
D
Explanation:
All the body's systems are linked together in some way. They all interact to produce a fully functioning organism.
A is not correct, becomes hormones are part of the endocrine system, not the immyne system.
B is not correct, because they are not explicitly involved in homeostasis
C is incorrect, all the systems are always working in the background.
The correct answer is D, one way in which the two systems are linked is that the cells of the immune system need to circulate around the body. The circulatory system is incredibly important for this, ensuring that the cells can reach their target sites
Answer:
it exchanges oxygen and carbon dioxide
