(picture)
Which of the following best explains why the two rat cell types are different?
Choose 1 answer:
(Choice A)
Because the cells have undergone mitosis, the adipocyte and the astrocyte contain different genes.
(Choice B)
Because of differential gene expression, the adipocyte and the astrocyte produce different proteins.
(Choice C)
Because the cells are the result of a fertilization event, the adipocyte and the astrocyte contain different chromosomes.
Answers
The statement 'due to differential gene expression, the adipocyte and astrocyte produce different proteins' explains why the two rat cell types are different.

The allele for red tomatoes (R) is dominant over the allele for yellow tomatoes (r). A farmer crosses a red tomato plant with a yellow tomato plant, and only red tomato plants are produced
Which of the following explains why no yellow tomato plants were produced?
A. Plants near the parent plants prevented the growth of yellow tomatoes.
B. Alleles for both red and yellow tomatoes were passed from the parent plants to the offspring, but only red was expressed.
C. The soil in which the parent plants grew prevented the growth of yellow tomatoes.
D. Only the allele for red tomatoes was passed down from the parent plants to the offspring, so that was the only color expressed.
Answers
Answer:
B.
The red allele is a parent allele, and capital R also represents a dominant allele. Lowercase r is recessive, meaning it will not be the dominant allele color. So for this, I would pick B. because it's not that there aren't any yellow tomato genes being passed down, it's that they are recessive meaning they will not make the tomato yellow.

Why tomatoes are red in colour??
Answers
Answer:
The color of a tomato begins to change as it ripens, from green to yellow, and ultimately to red. This is due to the breakdown of chlorophyll, which results in the formation of lycopene, a red carotenoid (a pigment group). When the tomato is fully ripe, the carotenoid becomes the predominate color, which is red.
