Answer:
b.It increases the likelihood that daughter cells contain different genetic material.
Explanation:
Morgan and Cattell for the first time used the term ‘crossing over’. Crossing over takes place during prophase I of meiosis. During crossing over, chromosome segments of non-sister chromatids of homologous chromosomes get exchanged. As a result, the daughter cells acquire different genetic materials. Thus, it provides genetic variation by creating a new combination of genes or get recombination and produces hybrids.
It’s B, having variation from sexual reproduction because the two parent mix genetic information so they have more of an advantage
Answer:
The independent variable are the vitamins .
The dependent variable are the rats.
Explanation:
The vitamins are the independent variable because they are are controllable. You can control how many vitamins the rats will be given.
significant digits are certain digits that give detail in a number
ex. in the number 400 it is the 4 because it tells you how many hundreds are in the number, in the number 49.92 it would be all of them because they all help understand the number
Do you get it?
