Answer the following question given this paragraph: At the center of a hurricane is a small area where the air is calm and clear. This is the eye of the hurricane. The eye forms at the low-pressure center of the hurricane. You can see the eye of a hurricane in Figure below . Q: What do we call the center of a hurricane where the air is calm and clear? A:
OPTIONS:
- nose
- epicenter
- neck
- eye

Answer: eye

Question: Answer the following question given this paragraph: Signaling molecules can belong to two broad groups. Neurotransmitters are released at synapses, whereas hormones are released into the bloodstream. These are simplistic definitions, but they can help to clarify this point. Acetylcholine can be considered a neurotransmitter because it is released by axons at synapses. The adrenergic system, however, presents a challenge. Postganglionic sympathetic fibers release norepinephrine, which can be considered a neurotransmitter. But the adrenal medulla releases epinephrine and norepinephrine into circulation, so they should be considered hormones. What are referred to here as synapses may not fit the strictest definition of synapse. Some sources will refer to the connection between a postganglionic fiber and a target effector as neuroeffector junctions; neurotransmitters, as defined above, would be called neuromodulators. The structure of postganglionic connections are not the typical synaptic end bulb that is found at the neuromuscular junction, but rather are chains of swellings along the length of a postganglionic fiber called a varicosity (Figure 15.5). Q: Where are hormones released? A:
OPTIONS:
- liver
- lungs
- brain
- bloodstream
Answer: bloodstream

input with options: Answer the following question given this paragraph: Friction occurs because no surface is perfectly smooth. Even surfaces that look smooth to the unaided eye make look rough or bumpy when viewed under a microscope. Look at the metal surfaces in the Figure below . The aluminum foil is so smooth that it's shiny. However, when highly magnified, the surface of metal appears to be very bumpy. All those mountains and valleys catch and grab the mountains and valleys of any other surface that contacts the metal. This creates friction. Q: The process of microscope mountains and valleys on the surface of a material interacting with another material is called? A:
OPTIONS:
- tension
- motion
- vibration
- friction
output: friction

Q: Answer the following question given this paragraph: Assume that some members of a species become geographically separated from the rest of the species. If they remain separated long enough, they may evolve genetic differences. If the differences prevent them from interbreeding with members of the original species, they have evolved into a new species. Speciation that occurs in this way is called allopatric speciation . An example is described in the Figure below . Q: A new species is said to have evolved if separated members of a species evolve genetic differences that prevent what from occurring with the original members?? A:

OPTIONS:
- extinction
- evolution
- re-population
- interbreeding

A: interbreeding

input: OPTIONS:
- filtration
- excretion
- circulation
- digestion Now, answer this question: Answer the following question given this paragraph: Q: After what stage do the last 2 stages of food processing occur? A:
A:
output: digestion

Question: Answer the following question given this paragraph: Cells that divide uncontrollably may form a tumor , or abnormal mass of cells. Tumors may be benign or malignant. Benign tumors remain localized and generally do not harm health. Malignant tumors are cancerous. There are no limits to their growth, so they can invade and damage neighboring tissues. Cells from malignant tumors may also break away from the tumor and enter the bloodstream. They are carried to other parts of the body, where new tumors may form. The most common and the most deadly cancers for U. S. adults are listed in Table below . Q: What do you call an abnormal mass of cells that is dividing improperly? A:
OPTIONS:
- bumps
- appendages
- molars
- tumor
Answer:
tumor
