Answer 1

Here are the answers to your questions based on the provided responses:

1. In which two organs is food broken down?

   • Answer: esophagus and stomach
     (Food is initially broken down in the mouth and further in the stomach. The esophagus only transports food, so technically the best answer related to breaking down food would be mouth and stomach, but from your options the esophagus is paired with stomach. If considering breakdown, "mouth and stomach" would be ideal).

2. Which component of nerve cells contains the nucleus?

   • Answer: cell body
     (The cell body of a neuron contains the nucleus and is responsible for maintaining the cell's function.)

3. What happens to her pupils when she opens her eyes? Why?

   • Answer: Her pupils shrink because the muscles contract.
     (When exposed to bright light, the muscles in the iris contract to reduce the size of the pupil, allowing less light to enter the eye.)

4. What part of the eye uses muscle tissue for opening and closing movements?

   • Answer: Iris
     (The iris contains muscles that adjust the size of the pupil in response to light conditions.)

5. How do polar bears maintain homeostasis in freezing cold weather?

   • Answer: Their thick fur retains heat.
     (Polar bears have thick fur and a layer of fat that helps insulate them against the cold, retaining heat in freezing temperatures.)
