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:
Exterior of the cell
Explanation:
Pancreas is a gland found behind the stomach and it secretes digestive enzymes into the duodenum.
Digestive enzymes are proteins hence leucine will form part of the enzymes.
Digestion of food takes approximately three hours. Therefore, if labelled Leucine is chased down with non radioactive leucine.
Black spots will appear on the exterior of the cells because digestive enzymes are extracellular enzymes .
I remember this from last year haha. The dark moths populations will go down since they can’t blend in as well as the light moths.
Arthropods were the first animals to successfully invade land from the sea
