input: OPTIONS:
- auxiliary nervous system
- significant nervous system
- function nervous system
- peripheral nervous system Now, answer this question: Answer the following question given this paragraph: The peripheral nervous system (PNS) consists of all the nervous tissue that lies outside the central nervous system. It is shown in yellow in Figure below . It is connected to the central nervous system by nerves. A nerve is a cable-like bundle of axons. Some nerves are very long. The longest human nerve is the sciatic nerve. It runs from the spinal cord in the lower back down the left leg all the way to the toes of the left foot. Like the nervous system as a whole, the peripheral nervous system also has two divisions: the sensory division and the motor division. Q: Which nervous system consists of all the nervous tissue that lies outside the central nervous system? A:
A:
output: peripheral nervous system

Answer the following question given this paragraph: A combustion reaction is a reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat. Combustion reactions must involve O 2 as one reactant. The combustion of hydrogen gas produces water vapor. Q: What chemical element is required for a combustion reaction ? A:

OPTIONS:
- carbon
- helium
- nitrogen
- oxygen

Answer: oxygen

Problem: OPTIONS:
- white blood cells
- mutated blood cells
- depleted blood cells
- red blood cells
Q: Answer the following question given this paragraph: Red blood cells transport oxygen to the tissues so they can function. In the absence of oxygen, cells cannot carry out their biochemical responsibilities. Oxygen moves to the cells attached to hemoglobin, a protein found in the red cells. In cases of carbon monoxide poisoning, CO binds much more strongly to the hemoglobin, blocking oxygen attachment and lowering the amount of oxygen reaching the cells. Treatment involves the patient breathing pure oxygen to displace the carbon monoxide. The equilibrium reaction shown below illustrates the shift toward the right when excess oxygen is added to the system:. Q: What type of blood cells transport oxygen to the tissues so they can function? A:
Answer: red blood cells

Problem:OPTIONS:
- hydrological symmetry
- skeletal symmetry
- biological symmetry
- radial symmetry

Answer the following question given this paragraph: Adult sea stars and other echinoderms have obvious radial symmetry. What evidence supports the claim that echinoderms evolved from an ancestor with bilateral symmetry?. Q: Adult sea stars have what kind of symmetry? A:
****
A: radial symmetry

Answer the following question given this paragraph: The decay of an unstable isotope to a stable element occurs at a constant rate. This rate is different for each parent-daughter isotope pair. The decay rate is measured in a unit called the half-life. The half-life is the time it takes for half of a given amount of an isotope to decay. For example, the half-life of carbon-14 is 5,730 years. Imagine that you start out with 100 grams of carbon-14. In 5,730 years, half of it decays. This leaves 50 grams of carbon-14. Over the next 5,730 years, half of the remaining amount will decay. Now there are 25 grams of carbon-14. How many grams will there be in another 5,730 years? The figure below graphs the rate of decay of a substance ( Figure below ). Q: The rate at which an unstable isotope decays is measured in a unit known as what? A:
OPTIONS:
- full-life
- staying-life
- half-time
- half-life
half-life

Answer the following question given this paragraph: The life sciences are so complex that most scientists focus on just one or two subspecialties. If you want to study insects, what would you be called? An entomologist. If you want to study the tiny things that give us the flu, then you need to enter the field of virology , the study of viruses. If you want to study the nervous system, which life science field is right for you ( Table below , Table below , and Table below )?. Q: What is the study of viruses called? A:
OPTIONS:
- immunology
- microbiology
- biotechnology
- virology

Answer:
virology
