Explanation:
You are going to use the chart where he graphed the data on his hamster's diet to dissect and identify, the parts of this scientific method.
TIP - try to think of this in a first-person perspective meaning try to think of this as you doing the experiment.
Hope this helped understand this assignment. :)
Answer:
Explanation:
Meiosis is a form of cell division that occurs in the sex cells of organisms. It ensures the reduction of a diploid cell to an haploid cell to allow for the formation of a diploid zygote after fertilization (contribution of both parents haploid sex cells to give a diploid zygote). Thus, this process is very essential and important.
The reduction is accomplished by 2 divisions after the duplication of chromosomes
- first division: separation of homologous pairs of chromosomes (this reduces the total in half)
- second division: separation of sister chromatids of a chromosome.
The rearrangement in meiosis occurs by crossing over/genetic recombination.
This is the exchange of genetic material between homologous pairs of chromosome bringing about a rearrangement and genetic variation
An example of a chromosomal abnormality that arises as a result of defects in this process is the Down Syndrome which is caused by a nondisjunction of the chromosomes 21 pair in a sex cell.
This condition produces offsprings that have some characteristic facial features, short stature etc
Sex is important because its how we reproduce we create new life so that they can create new life and so on with out sex theres no life if that makes sense
The answer is , because one cell divides to form two identical cells.
