Cell growth occurs in interphase.
The cell cycle is composed of interphase, mitosis, and cytokinesis. It can be described in five steps.
The first three steps of the cell cycle are called the interphase. This is where the cell grows, the cell matures, and where the cell carries out its life function. The fourth step is mitosis and the fifth step is cytokinesis.
The interphase has three stages. These are Gap 1, synthesis, and Gap 2.
Gap 1 or growth 1 - where the cell grows and functions normally. Cell growth is twice its original size.
Synthesis - where cell duplicates its DNA
Gap 2 or growth 2 - where cell resumes its growth in preparation for division.
Answer:
external
Explanation:
<em>Through the process of photosynthesis, plants use the sun's energy to make sugars to function. External means from an outside force, while internal means from within. Since the sun isn't inside a plant, they gather it from outside, thus it's external.</em>
Answer:
The cross is as follows:
P: D/d × d/d
Explanation:
Half of the F1 progeny are mutant. The mutation results in 3 cotyledons is dominant and the original mutant is heterozygous.
If D denotes the mutant allele and d denotes the wild type allele.
The cross is as follows:
P: D/d × d/d
F1 denotes D/d three cotyledons
d/d denote two cotyledons
I think the correct answer would be A. The yolk sac becomes the placenta. It is membranous sac that is attached to the embryo. It provides all the nutrition and the blood cells needed by the embryo. It is also called the umbilical vesicle.
