The mesenteric veins and the hepatic portal vein
The parents both need to be heterozygous, meaning they have to have one dominant and one recessive allele.
Answer and Explanation:
The cell division cycle is responsible for increasing and maintaining cell number and size. This cycle is an essential feature of living organisms. There are four phases of cell division mitotic phase (M phase), growth phase 1 (G1), growth phase 2 (G2), and synthesis phase (S). One phase of the cell cycle ends, and the other starts; this is named a phase transition—a unidirectional alteration in the cell cycle phases. During G1, G2, and S phase cell grows and during the M phase cell divides. There are two models of cell reproduction as the clock model and the domino model. The domino model implies that cell division phases must occur in a distinct order and at a definite time. The domino model recommends that the cell cycle events are independent, while the clock model shows that the effectiveness of mitosis entrance was not persuaded by other actions.
Answer:
(C) each cell of an organism has all the genes needed for development.
Explanation:
According to my research on studies conducted on Genetics, I can say that based on the information provided within the question this illustrates that each cell of an organism has all the genes needed for development. If this were not the case then the frog would either not be born or would be born with serious abnormalities because the cell did not have the necessary genes needed for the frog to form correctly.
