Q: Answer the following question given this paragraph: Wavelength is one way of measuring the size of waves. It is the distance between two corresponding points on adjacent waves, and it is usually measured in meters. How it is measured is a little different for transverse and longitudinal waves. Q: What do wavelengths measure the size of? A:
Answer: waves

Problem:OPTIONS:
- cell
- organ system
- organism
- organ

Answer the following question given this paragraph: After tissues, organs are the next level of organization of the human body. An organ is a structure that consists of two or more types of tissues that work together to do the same job. Examples of human organs include the brain, heart, lungs, skin, and kidneys. Human organs are organized into organ systems, many of which are shown in Figure below . An organ system is a group of organs that work together to carry out a complex overall function. Each organ of the system does part of the larger job. Q: What is a structure that consists of two or more types of tissues that work together to do the same job? A:
****
A: organ

Answer the following question given this paragraph: All of these animal behaviors are important. They help the animals get food for energy, make sure their young survive, or ensure that they, themselves, survive. Behaviors that help animals or their young survive, increase the animals' fitness. Animals with higher fitness have a better chance of passing their genes on to the next generation. If genes control behaviors that increase fitness, the behaviors become more common in the species. This occurs through the process of evolution by natural selection. Q: Fitness and natural selection are parts of what theory that might describe how organisms change over time? A:
OPTIONS:
- dessication
- gravity
- implementation
- evolution
evolution

Answer the following question given this paragraph: The Ventricles There are four ventricles within the brain, all of which developed from the original hollow space within the neural tube, the central canal. The first two are named the lateral ventricles and are deep within the cerebrum. These ventricles are connected to the third ventricle by two openings called the interventricular foramina. The third ventricle is the space between the left and right sides of the diencephalon, which opens into the cerebral aqueduct that passes through the midbrain. The aqueduct opens into the fourth ventricle, which is the space between the cerebellum and the pons and upper medulla (Figure 13.18). Q: What organ has four ventricles, all of which developed from the original hollow space within the neural tube? A:
OPTIONS:
- heart
- liver
- bladder
- brain

Answer: brain

Question: Answer the following question given this paragraph: Molecules within a liquid are pulled equally in all directions by intermolecular forces. However, molecules at the surface are pulled downwards and sideways by other liquid molecules, but not upwards away from the surface. The overall effect is that the surface molecules are pulled into the liquid, creating a surface that is tightened like a film. This phenomenon is referred to as surface tension . Liquids that have strong intermolecular forces, like the hydrogen bonding in water, exhibit the greatest surface tension. Table below shows surface tension values for various common liquids. Q: Surface tension is a property of matter that is in what state? A:
OPTIONS:
- mixture
- water
- Base
- liquid
Answer: liquid

input: OPTIONS:
- gold
- precipitation
- sound
- heat Now, answer this question: Answer the following question given this paragraph: The enthalpy of the reactants is greater than the enthalpy of the products. During the course of the reaction, heat is released to the surroundings. Q: What is released during an enthalpy reaction? A:
A:
output:
heat
