Q: Answer the following question given this paragraph: Some mixtures are homogeneous. This means they have the same composition throughout. An example is salt water in the ocean. Ocean water everywhere is about 3.5 percent salt. Q: Mixtures that have the same composition throughout are known as what kinds of mixtures? A:

OPTIONS:
- contiguous
- zygomatic
- heterogeneous
- homogeneous

A: homogeneous

input: OPTIONS:
- dying
- feeding
- migrating
- spawning Now, answer this question: Answer the following question given this paragraph: Wild male and female Sockeye salmon before spawning. Sockeye salmon are blue tinged with silver in color while living in the ocean. Just prior to spawning, both sexes turn red with green heads. Sockeye spawn mostly in streams having lakes in their watershed. The young fish spend up to three years in the freshwater lake before migrating to the ocean. Migratory fish spend from one to four years in salt water, and thus are four to six years old when they return to spawn. Navigation to the home river is thought to be done using the characteristic smell of the stream, and possibly the sun. Q: Both sexes of sockeye salmon turn red with green heads just prior to what? A:
A:
output: spawning

Answer the following question given this paragraph: Many skeletal muscles are attached to the ends of bones where they meet at a joint. The muscles span the joint and connect the bones. When the muscles contract, they pull on the bones, causing them to move. Q: Where do skeletal muscles usually attach? A:

OPTIONS:
- to cartilage
- to dendrites
- to the spine
- end of bones

Answer: end of bones

Answer the following question given this paragraph: Most allergies can be treated with medicines. Medicines used to treat allergies include antihistamines and corticosteroids. These medicines help control the immune system when it attacks an allergen. Sometimes, allergies cause severe symptoms, a condition known as anaphylaxis. For example, they may cause the throat to swell so it is hard to breathe. Severe allergies may be life threatening. They require emergency medical care. Q: Prescribed to treat allergies, antihistamines and corticosteroids help control what system that attacks allergens? A:
****
A: immune system

Problem:OPTIONS:
- tails

Answer the following question given this paragraph: The ears are also responsible for the sense of balance. Balance is the ability to sense and maintain body position. The semicircular canals inside the ear (see Figure above ) contain fluid that moves when the head changes position. Tiny hairs lining the semicircular canals sense movement of the fluid. In response, they send nerve impulses to the vestibular nerve, which carries the impulses to the brain. The brain interprets the impulses and sends messages to the peripheral nervous system. This system maintains the body's balance by triggering contractions of skeletal muscles as needed. Q: What external feature in human beings is responsible for balance? A:
****
A:
ears
