Question

1. tasha and her grandson are working outside in her garden on a hot summer day. she starts to sweat as she is working. what major theme of biology describes why tasha is sweating?

structure and function
systems
evolution
homeostasis

Explanation:

To solve this, we analyze each option:

• "structure and function" relates to how a part's structure enables its function, not sweating regulation.
• "systems" refers to interacting parts, not directly about maintaining internal balance.
• "evolution" is about species change over time, irrelevant here.
• "homeostasis" is the body's ability to maintain stable internal conditions (like temperature). Sweating cools the body, helping maintain temperature homeostasis.

Answer:

D. homeostasis
