Explanation:
Gregor Mendel was an Austrian monk who laid the foundation of genetics. Mendel studies seven traits from the pea plants and formed the law of segregation and law of independent assortment.
The work of Mendel was not appreciated until his death. In the 20th century, his work was eventually rediscovered and appreciated.
However, Mendel's study did not include any explanations for polygenic traits. His results could predict heritability in both plants and animals.

Science starts with observing which leads to hypothesis, which is tested by experiments.
The other two i am not sure of. Hope i was a help to you. One thing you can do to figure out the other two is google: "what type of science includes medicine and envirnmental science", and do the same for the other one.
