Answer:
A Punnett square is shown. The columns are labeled Upper D and d. The rows are labeled d and d. Clockwise from upper left the boxes contain: Upper D d, d d, d d, Upper D d.
Explanation:
Punnett square is used to depict the cross between two organisms. Progeny genotypes can be determined by punnett square. Columns and rows are labelled according to the alleles present in the genotype of respective parents, in this case the mom and the dad.
It has been given that the mom is heterozygous for dimples trait. Since, heterozygous genotype has two different alleles together, mom's genotype must be Dd. Dad is homozygous for no dimples so he can either be DD or dd depending on the dominance nature of the trait. Out of the given options, only the selected option has one heterozygous genotype (Dd) and one homozygous genotype (dd) together hence it is the correct option.

Answer:
Proteins would be made in ribosomes.
Answer:
Root hair cells are alive and therefore need energy, which is why root hair cells contain many mitochondria in them. Root hair cells don't contain chloroplasts. Chloroplasts are used by the plant to make food using light energy. Since the roots aren't exposed to any form of light, they have no need for chloroplasts.
Answer:
Oncogenes.
Explanation:
Cancer is the harmful disease that causes several death in the world. Cancer occur due to the mutation in the genes that are responsible for the regulation of apoptosis and cell divisions.
The virus are also oncogenic in nature and can cause several different type of cancer. The human papilloma virus can be transmitted from the skin contact. The virus cause cervical cancer and genital warts. The integration of this virus into host genome increases the expression of viral oncogenes in the host DNA.
Thus, the answer is oncogenes.
