Question

choose 1 answer:
a environmental
conditions determined
the genotypes of the
kale plants in each
group, causing one
group to produce more
flavonoids than the
other.

b the group of kale plants
grown in cold
temperatures had less
access to water, which
caused them to
produce more
flavonoids than kale
plants grown in warm
temperatures.

c different temperatures
affected the kale plants
gene expression
patterns and their
resulting flavonoid
production phenotypes.

Explanation:

• Option A: Environmental conditions do not determine genotypes (genotypes are inherited), so A is incorrect.
• Option B: The question likely relates to temperature affecting flavonoid production, and there's no indication water access differs by temperature group, so B is incorrect.
• Option C: Temperature can affect gene expression (epigenetic or regulatory effects), leading to different flavonoid production phenotypes, which is consistent with biological principles.

Answer:

C. Different temperatures affected the kale plants' gene expression patterns and their resulting flavonoid production phenotypes.
