Literally just had a test on this today :)
1 is correct.
2 is correct.
3: does true breeding like a purebred/homozygous/two of the same traits?
if so, all of the plants will show the dominant allele, so the answer is B
4 is correct.
5: 23 because when they combine, the chromosomes mix, and there are 46 in a regular cell. Half com from one parent, and half from the other, so the answer is A
6: homo is a prefix that means “same”, and zygous has something to do with genes, so the answer is homozygous
7 is correct
8 is correct
9: i have a strange felling that it is alleles, but DNA could also work, so I’m not quite sure on this one, sorry…
10: alleles are the different forms of a gene. Genes are transferred to you from your parents hereditarily. An allele for stem height would be T or t, but a gene would be TT, Tt, or tt.
I really hope this helps you! It was a hard unit for me, but i did get 100% on the test, and I’m sure you can too.

By studying sedimentary rocks from the Earth's crust, we can learn about the history of how Earth's surface has changed over time
Explanation:
I'm sure it's a hope this helps
When the rate of repair lags behind the rate of mutation, the possible fate of the cell is that (A) The cell can be transformed into a cancerous cell.
Mutations are the changes in the sequence of genes. If the rate of repair lags behind, there is a major possibility that the cell can turn into a cancerous one. This is because mutations are a big reason for the appearance of cancer.
A cancerous cell is the one that proliferates at an excessive rate. The most important property of cancerous cell is of metastasis. It is the movement of the tumor into different parts of the body and infect the healthy cells of that area as well.
