Answer the following question given this paragraph: It's obvious that living things are important natural resources needed by human beings. After all, other species provide us with all of the food we eat. We couldn't survive without them. But that's far from the only reason that other species are important for human survival. Biodiversity is an important natural resource in and of itself. Q: Name an important natural resource in and of itself. A:
OPTIONS:
- habitat
- food chain
- water
- biodiversity
biodiversity

Answer the following question given this paragraph: Diseases of the cardiovascular system are common and may be life threatening. Examples include atherosclerosis and coronary heart disease. A healthy lifestyle can reduce the risk of such diseases developing. This includes avoiding smoking, getting regular physical activity, and maintaining a healthy percent of body fat. Q: Atherosclerosis and coronary heart disease are examples of what type of body system disease? A:
OPTIONS:
- connective system
- digestive system
- excretory system
- cardiovascular system

Answer: cardiovascular system

Question: Answer the following question given this paragraph: Still other pathogens are spread by vectors. A vector is an organism that carries pathogens from one person or animal to another. Most vectors are insects such as ticks or mosquitoes. They pick up pathogens when they bite an infected animal and then transmit the pathogens to the next animal they bite. Ticks spread the bacteria that cause Lyme disease. Mosquitoes spread the protozoa that cause malaria. Q: An organism that carries pathogens from one individual to another is called what? A:
OPTIONS:
- germ cell
- virus
- host
- vector
Answer: vector

input with options: Answer the following question given this paragraph: Many animals go through daily cycles. Daily cycles of behavior are called circadian rhythms. For example, most animals go to sleep when the sun sets down and wake up when the sun rises. These animals are active during the day and called diurnal. Other animals go to sleep when the sun rises and wake up when the sun sets. These animals are active during the night and called nocturnal. Many owls, like the owls in Figure below , are nocturnal. Like some other nocturnal animals, they have large eyes that are specially adapted for seeing when light levels are low. Q: What term refers to an animal that sleeps during the day and is active at night? A:
OPTIONS:
- diurnal
- crepuscular
- solitary
- nocturnal
output: nocturnal

Q: Answer the following question given this paragraph: Harmless fungi can be used to control pathogenic bacteria and insect pasts on crops. Fungi compete with bacteria for nutrients and space, and they parasitize insects that eat plants. Fungi reduce the need for pesticides and other toxic chemicals. Q: What reduces the need for pesticides and other toxic chemicals? A:

OPTIONS:
- pollen
- helium
- yeast
- fungi

A: fungi

Answer the following question given this paragraph: When using measuring devices, we often use a technique called calibration to increase the accuracy of our measurements. Calibration is a method of setting or correcting a measuring device by matching it to known measurement standards. To better understand calibration, we will look at the example of calibrating a thermometer. All thermometers are slightly different in their temperature readings. One way to calibrate a thermometer is by using the freezing point and boiling point of water ( Figure below ). If we know that water freezes at 0C and boils at 100C, we can calibrate our thermometer by measuring the temperature of ice water and of boiling water. We place the thermometer in ice water and wait for the thermometer liquid to reach a stable height, then place a mark at this height which represents 0C. Then we place the thermometer in boiling water, and after waiting for the thermometer liquid to reach a stable height, we place a mark at this height which represents 100C. We can then place 100 equally spaced divisions between our 0 and 100C marks to each represent 1C. Our thermometer has now been calibrated using the known values for the freezing point and boiling point of water, and can be used to measure temperatures of objects between 0 and 100C. Q: What is the method of setting or correcting a measuring device by matching it to known measurement standards called? A:
OPTIONS:
- parallax
- distortion
- precision
- calibration
