Answer:
8,324,608 chromosome combinations
Explanation:
During meiosis, chromosomes separate independently so that only one chromosome came from the father and the other homologous chromosome came from the mother. This process of independent assortment produces a huge amount of possible combinations in the diploid zygote cell. In humans, the haploid number of chromosomes is n = 23, thereby there are 2²³ = 8,324,608 chromosome combinations. Thus, the independent assortment of chromosomes during meiosis is a key factor that contributes to genetic variation in the offspring.
Answer:
A difference between plant cells and animal cells is that most animal cells are round whereas most plant cells are rectangular. Plant cells have a rigid cell wall that surrounds the cell membrane.
Explanation:
The answer would be Prevent yourself from knowing what was in the pill bottles, and distributed the bottles randomly to the subjects
When researcher know which group got the treatment and which group got placebo, they might be biased. It will be better if the researcher is "blinded" and ask third party to help labeling the drug. The drug should be distributed randomly to makes the subject in control and treatment group as similar as possible.
