Question

1. you want to test how nutrient availability affects the g1 phase in cultured human cells. which experimental observation would best support your hypothesis that low nutrients lengthen g1? cells in low - nutrient media spend more time in g1 compared to cells in normal media. cells in low - nutrient media skip g1 entirely. cells in low - nutrient media progress faster through mitosis. cells in low - nutrient media undergo apoptosis immediately.

Explanation:

The hypothesis is that low nutrients lengthen G1. The observation that cells in low - nutrient media spend more time in G1 compared to cells in normal media directly supports this hypothesis. Skipping G1 entirely, faster mitosis progress, or immediate apoptosis do not indicate lengthening of G1.

Answer:

Cells in low - nutrient media spend more time in G1 compared to cells in normal media.
