Photosynthesis & Resp

One of the most common examples of homeostasis is body temperature. When your body temperature rises above normal, how does your body respond?

• shivers

• sweats

• coughs

What might happen if you didn't run a fever when you got sick?

• You would recover much more quickly

• Your temperature would drop to dangerous levels

• Your body wouldn't fight the infection as efficiently as it could

What would be the response to increased body temperature if it acted through negative feedback?

• Sweating to decrease the temperature

• Shivering to increase the temperature

• Adding clothing to increase the temperature

• There would not be a response

When you exercise, what gas does your body NEED more of?

• Blood

• Carbon dioxide

• Hydrogen

• Oxygen

Which of the following describes homeostasis?

• keeps variables exactly at the set point

• organism's ability to maintain steady(stable) internal conditions

• acts to keep values outside of a desired range

• operates through positive feedback

The balanced maintenance of an organism’s internal environment is called:

• compensating

• homeostasis

• balancing

• routine

The group of organisms that use the process of homeostasis includes

• mammals, only

• animals, only

• plants and animals

• all living things

Which of the following is not an examples of an organism maintaining internal homeostasis?

• Shivering when cold

• Sweating when hot

• Going for a walk

• Vomiting - releases toxins and wastes

A football player perspires during a football game. The sweat is a cooling mechanism. What is this an example of?

• Digestion

• Mitosis

• Homeostasis

• Respiration

You are growing a tomato plant in your house. Which of the following would the plant probably do to help maintain homeostasis?

• Grow away from the light coming from the window

• Grow toward the light coming from the window

• Growth is not affected by the light coming from the window
