Question

(b)
part b
which statement best explains how the answer from part a results in a faster change in the traits of a spider plant?
a artificial selection always results in the desired trait changes in the first generation.
b artificial selection helps control which traits survive, resulting in trait changes over fewer generations.
c natural selection always results in the desired trait changes in the first few generations.
d natural selection favors the survival of specific traits, resulting in trait changes over several generations.

Explanation:

To solve this, we analyze each option:

• Option A: Artificial selection doesn't always get desired traits in the first generation (too absolute), so A is wrong.
• Option B: Artificial selection (like a botanist developing a new plant) allows humans to control which traits are selected, so changes happen in fewer generations. This matches the idea of faster trait change.
• Option C: Natural selection isn't about "desired" traits (it's about survival in environment) and doesn't always get changes in first few generations, so C is wrong.
• Option D: Natural selection takes many generations, so it's not faster. Also, the Part A answer (likely artificial selection, like a botanist developing a plant) isn't natural selection, so D is wrong.

Answer:

B. Artificial selection helps control which traits survive, resulting in trait changes over fewer generations.
