Question

a drought reduces available water in an area. which variation would be an advantage?
plants that need more water
animals with thick fur
plants with deep root systems
animals that require cooler temperatures

Explanation:

• For "Plants that need more water", a drought reduces water, so these plants would struggle, not an advantage.
• "Animals with thick fur" is related to temperature regulation, not water availability during drought, so not relevant.
• "Plants with deep root systems" can access water from deeper soil layers when surface water is scarce due to drought, which is an advantage.
• "Animals that require cooler temperatures" is about temperature, not water availability in drought, so not an advantage.

Answer:

C. Plants with deep root systems
