A developmental biologist is researching how cells in a frog embryo differentiate into various tissues. She discovers that certain cells only start changing into nerve cells when exposed to a specific hormone produced by the embryo.
What does this observation suggest about the role of hormones in cell differentiation?

Hormones provide energy needed for cell growth.

Hormones only assist in cell division without affecting differentiation.

Hormones signal specific genes to activate or deactivate, influencing cell specialization.

Researchers are studying the effect of diet on cell differentiation in fruit flies. They discover that when larvae are given a diet enriched with certain nutrients ( good food) , they develop into queens, whereas those on a standard diet (not as good food) become worker bees.
What can be inferred about the role of diet in cell differentiation?

Specific nutrients can trigger changes in gene expression that result in different cell specializations.

Diet only provides energy without affecting cell differentiation.

The type of diet does not influence cell differentiation.
