The nephrons are the functional units of the kidney that are majorly responsible for the filtering action. The longer the nephron loops are more concentrated urine is expelled from the body.
Answer:
It is an answer to a scientific question and is based mostly on research.
Explanation:
Mendel five part hypothesis was also known as the law of segregation. This law explain the how traits are inherited in living organisms. Mendel's theory discovered that there are two alleles for a single gene and that one of these alleles is inherited from each parent, which forms the basis of the trait in the progeny(offspring).
Mendel’s hypothesis was considered true after various experiments and analysis and also answer the question of how the different traits are passed on from parent to progeny. This validates it being an answer to a scientific question and it being based mostly on research.
