Answer:

A

Explanation: A,  because the foundation of biological evolution is changes in gene frequency in a population occur from one generation to the next. Mutation, migration, genetic drift, and natural selection along with sexual reproduction result in genetic variation or changes in gene frequency.

Control and experimental groups. They repeated their experiment several times and found the results were the same.
Ira Lisetskai [31]

Answer: Experience 1 is the one that has the greatest reliability.

Explanation:    Because of this potential variation, biological experiments need to have a large sample size and preferably be repeated several times.  With more samples and repeating the experiment more often, the probability of arriving at a wrong conclusion due to random variation is diminished. As experience 1 has had several repetitions, it is the experience with a more reliable result.

Sever21 [200]

Explanation:

An autoimmune disorder occurs when the body sees it's own cells as foreign antigens and begins to attack them.

The treatment depends on the particular autoimmune disorder; however, the mainstay of treatment is the use of IMMUNOSUPPRESSIVE MEDICATION. Examples include corticosteroids (such as prednisone) and nonsteroid drugs such as azathioprine, cyclophosphamide, mycophenolate, sirolimus, or tacrolimus.

Kisachek [45]

Answer: Placebo effect

John is experiencing placebo effect where the pill that contains no pain killing medication has given pain relief to John. A placebo is a substance with no therapeutic effect but sometimes improves patient’s condition. This is due to patient’s expectation that the pill they take can help or ease the pain they have even if no active ingredient is present.

Therefore, the effect is more than positive thinking or believing that a treatment will work by creating a stronger connection between the brain and body as they work together.

What does paleontology, biogeography, embryology, and anatomy reveal bout evolution
Ugo [173]

Paleontology deals with fossils and helps in learning the changes of living organisms in sequence.

Biogeography deals with the distribution of species across the mother earth.

Embryology deals with the study of the similarities and difference that exists in the embryos of different species or organisms.

Anatomy deals with the study of the similarities and difference that exists among different species or organisms.

<u>Explanation: </u>

As an organism dies, the remaining of these organisms will be buried in soil. These are fossils. Paleontology supports evolution with the information that are related to the fossils, footprints etc. With these we can study the evolution of organisms and also the changes they undergo. There are some technologies like radiometric dating that can be used for the determination of these rocks and fossils ages.

Charles Darwin suggested that the evolution of species were form their ancestor. Biogeography supports evolution by explaining about the distribution of different species over the earth. Embryology and Anatomy supports evolution by describing about the similarity and difference in the species of living organisms. Embryology deals with the embryos and anatomy deals with the structure.
