Problem:OPTIONS:
- neuroreceptors
- nociceptors
- fibroblasts
- mechanoreceptors

Answer the following question given this paragraph: Q: What do some animals use to get a feel for their environment? A:

A: mechanoreceptors

Answer the following question given this paragraph: Blood flows in only one direction in the heart. Blood enters the atria, which contract and push blood into the ventricles. The atria relax and the ventricles fill with blood. Finally, the ventricles contract and push blood around the body. Q: Blood enters the heart in what valve? A:
OPTIONS:
- tricuspid
- aortic
- mitral
- atria
atria

Answer the following question given this paragraph: A N SW E R S 1. Gases consist of tiny particles of matter that are in constant motion. Gas particles are constantly colliding with each other and the walls of a container. These collisions are elastic; that is, there is no net loss of energy from the collisions. Gas particles are separated by large distances, with the size of a gas particle tiny compared to the distances that separate them. There are no interactive forces (i. , attraction or repulsion) between the particles of a gas. The average speed of gas particles is dependent on the temperature of the gas. Q: Gas particles are constantly colliding with each other and the walls of a container, and these collisions are elastic, so there is no net loss of what? A:
OPTIONS:
- velocity
- heat
- temperature
- energy

Answer: energy

Question: Answer the following question given this paragraph: Inside the atom, two types of subatomic particles have electric charge: electrons, which have an electric charge of -1, and protons, which have an opposite but equal electric charge of +1. The model of an atom in the Figure below shows both types of charged particles. Protons are found inside the nucleus at the center of the atom, and they give the nucleus a positive charge. (There are also neutrons in the nucleus, but they have no electric charge. ) Negative electrons stay in the area surrounding the positive nucleus because of the electromagnetic force of attraction between them. Q: What kind of charges do protons give the nucleus? A:
OPTIONS:
- negative
- dynamic
- neutral
- positive
Answer: positive

input: OPTIONS:
- autotrophic
- exothermic
- hydrostatic
- endothermic Now, answer this question: Answer the following question given this paragraph: Anabolic reactions involve forming bonds. Smaller molecules are combined to form larger ones. For example, simple sugars are combined to form complex carbohydrates. Anabolic reactions require energy, so they are endothermic. Q: Anabolic reactions require energy, so they are considered what type of reaction? A:
A:
output:
endothermic
