input with options: Answer the following question given this paragraph: Muscle contraction occurs when muscle fibers get shorter. Literally, the muscle fibers get smaller in size. To understand how this happens, you need to know more about the structure of muscle fibers. Q: What occurs when muscle fibers get shorter? A:
OPTIONS:
- muscle extension
- muscle tension
- muscle diffusion
- muscle contraction
output: muscle contraction

Q: Answer the following question given this paragraph: The kidneys are the chief organs of the urinary system. Q: What is the chief organ of the urinary system? A:

OPTIONS:
- liver
- bladder
- lung
- kidney

A: kidney

input: OPTIONS:
- cilia
- timpani
- hammer and anvil
- the cochlea Now, answer this question: Answer the following question given this paragraph: The stirrup in the middle ear passes the amplified sound waves to the inner ear through the oval window. When the oval window vibrates, it causes the cochlea to vibrate as well. The cochlea is a shell-like structure that is full of fluid and lined with nerve cells called hair cells. Each hair cell has many tiny "hairs," as you can see in the magnified image below . When the cochlea vibrates, it causes waves in the fluid inside. The waves bend the "hairs" on the hair cells, and this triggers electrical impulses. The electrical impulses travel to the brain through nerves. Only after the nerve impulses reach the brain do we hear the sound. Q: When the oval window vibrates, it causes what else to vibrate as well? A:
A:
output: the cochlea

Answer the following question given this paragraph: Homeostasis refers to the balance, or equilibrium, within the cell or a body. It is an organism's ability to keep a constant internal environment. Keeping a stable internal environment requires constant adjustments as conditions change inside and outside the cell. The adjusting of systems within a cell is referred to as homeostatic regulation. Because the internal and external environments of a cell are constantly changing, adjustments must be made continuously to stay at or near the normal proportions of all internal substances. This involves continual adjustments in transport of substances across the cell membrane. Homeostasis is a dynamic equilibrium rather than an unchanging state. The cellular processes discussed in the cell transport (passive and active transport) concepts all play an important role in homeostatic regulation. Q: What term means the adjusting of systems within a cell in order to restore balance or maintain equilibrium? A:

OPTIONS:
- systemic regulation
- aftertouch regulation
- gaseous regulation
- homeostatic regulation

Answer: homeostatic regulation

Problem: OPTIONS:
- lungs
- testes
- kidneys
- ovaries
Q: Answer the following question given this paragraph: The two ovaries are small, egg-shaped organs that lie on either side of the uterus. They produce eggs and secrete estrogen. Each egg is located inside a structure called a follicle. Cells in the follicle protect the egg and help it mature. Q: What are the egg shaped organs on either side of the uterus? A:
Answer: ovaries
