Explanation:
I changed the wording so it cant be traced, but some websites had the answer key.
A new species is formed when there is a change in the dna or mutation.
Answer:
Which of the following was the MAIN difference between the explanations proposed by Lamarck and Darwin?

B.
Lamarck based his explanation on the idea that the earth was 6,000 years old.
C.
Lamarck used the evidence provided by the fossil record as a basis for his explanation.
D.
<em><u>Lamarck’s explanation included the idea that individual organisms can evolve within their lifetimes.✓</u></em>
According to Darwin’s theory, organisms that are the most fit
A.
have the longest life spans.
B.
have the best overall health.
C.

D.
are best suited for capturing prey and avoiding predators.
1) Cells duplicate their chromosomes before dividing instead of after because the daughter cells would each lose one-half of the genetic information.
The duplication of chromosomes automatically leads to the duplication of the genetic information on the chromosomes and each daughter cell receives a copy each of the genetic information.
If the information are not duplicated before dividing, it means that each daughter cell will receive half information.
2) If a cell that starts with 16 chromosomes lost half of its genes during each cell division, it will take 4 divisions for the gene to remain 1.
- First division, the genes would remain 8 from 16
- Second division, the genes would remain 4
- Third division, the genes would remain 2
- Fourth division, the gene would remain only 1.
