Q: Answer the following question given this paragraph: Some reactions need extra help to occur quickly. They need another substance called a catalyst. A catalyst is a substance that increases the rate of a chemical reaction. A catalyst isn't a reactant, so it isn't changed or used up in the reaction. Therefore, it can catalyze many other reactions. Q: Some reactions need extra help to occur quickly. they need another substance called what? A:

OPTIONS:
- neurotransmitter
- protein
- hormone
- a catalyst

A: a catalyst

input: OPTIONS:
- h2
- AB
- RNA
- rh Now, answer this question: Answer the following question given this paragraph: Rhesus blood type is determined by one common antigen. A person may either have the antigen (Rh + ) or lack the antigen (Rh - ). Q: What is the common abbreviation for noting the rhesus blood type? A:
A:
output: rh

Answer the following question given this paragraph: Light includes infrared light, visible light, and ultraviolet light. As you can see from the Figure above , light falls roughly in the middle of the electromagnetic spectrum. It has shorter wavelengths and higher frequencies than microwaves, but not as short and high as X rays. Q: What falls roughly in the middle of the electromagnetic spectrum, having shorter wavelengths and higher frequencies than microwaves, but not as short and high as x rays? A:

OPTIONS:
- radio waves
- ultraviolet light
- gamma rays
- light

Answer: light

Problem: OPTIONS:
- immune transport
- bacterial transport
- active transport
- passive transport
Q: Answer the following question given this paragraph: Passive transport requires no energy. It occurs when substances move from areas of higher to lower concentration. Types of passive transport include simple diffusion, osmosis, and facilitated diffusion. Q: What type of transport requires no energy and occurs when substances move from areas of higher to lower concentration? A:
Answer: passive transport

Problem:OPTIONS:
- shows free charges
- less free charges
- need free charges
- many free charges

Answer the following question given this paragraph: Good conductors have large numbers of free charges in them. In metals, the free charges are free electrons. Figure 20.6 shows how free electrons move through an ordinary conductor. The distance that an individual electron can move between collisions with atoms or other electrons is quite small. The electron paths thus appear nearly random, like the motion of atoms in a gas. But there is an electric field in the conductor that causes the electrons to drift in the direction shown (opposite to the field, since they are negative). The drift velocity v d is the average velocity of the free charges. Drift velocity is quite small, since there are so many free charges. If we have an estimate of the density of free electrons in a conductor, we can calculate the drift velocity for a given current. The larger the density, the lower the velocity required for a given current. Q: Why is the drift velocity negligible? A:
****
A: many free charges

Problem:OPTIONS:
- square-shaped
- snake - shaped
- triangle-shaped
- butterfly-shaped

Answer the following question given this paragraph: Thyroid Gland The thyroid gland is located in the neck, just below the larynx and in front of the trachea, as shown in Figure 37.16. It is a butterfly-shaped gland with two lobes that are connected by the isthmus. It has a dark red color due to its extensive vascular system. When the thyroid swells due to dysfunction, it can be felt under the skin of the neck. Q: What is the shape of the thyroid gland? A:
****
A:
butterfly-shaped
