Answer the following question given this paragraph: Biochemistry is the study of chemical processes that occur in living things. Research may cover basic cellular processes up to understanding disease states so better treatments can be developed. Q: What is the study of chemical processes that occur in living things? Choices: - phrenology - physiology - cardiology - biochemistry A:
biochemistry

Answer the following question given this paragraph: A colloid is a homogeneous mixture with medium-sized particles. Examples include homogenized milk and gelatin. The particles of a colloid are large enough to reflect light, so you can see them. But they are too small to settle or filter out of the mixture. Q: A colloid is a homogeneous mixture with medium-sized what? Choices: - atoms - solutions - molecules - particles A:
(Answer)
particles

Ans: the ovary

Answer the following question given this paragraph: Functional Receptor Types A third classification of receptors is by how the receptor transduces stimuli into membrane potential changes. Stimuli are of three general types. Some stimuli are ions and macromolecules that affect transmembrane receptor proteins when these chemicals diffuse across the cell membrane. Some stimuli are physical variations in the environment that affect receptor cell membrane potentials. Other stimuli include the electromagnetic radiation from visible light. For humans, the only electromagnetic energy that is perceived by our eyes is visible light. Some other organisms have receptors that humans lack, such as the heat sensors of snakes, the ultraviolet light sensors of bees, or magnetic receptors in migratory birds. Receptor cells can be further categorized on the basis of the type of stimuli they transduce. Chemical stimuli can be interpreted by a chemoreceptor that interprets chemical stimuli, such as an object's taste or smell. Osmoreceptors respond to solute concentrations of body fluids. Additionally, pain is primarily a chemical sense that interprets the presence of chemicals from tissue damage, or similar intense stimuli, through a nociceptor. Physical stimuli, such as pressure and vibration, as well as the sensation of sound and body position (balance), are interpreted through a mechanoreceptor. Another physical stimulus that has its own type of receptor is temperature, which is sensed through a thermoreceptor that is either sensitive to temperatures above (heat) or below (cold) normal body temperature. Q: Pressure and vibration are examples of what type of stimuli? Choices: - chemical - atmospheric - thermal - physical A:
(A).
physical
Ques:Answer the following question given this paragraph: In addition to sunlight, aquatic producers also need dissolved oxygen and nutrients. Water near the surface generally contains more dissolved oxygen than deeper water. Many nutrients enter the water from the land. Therefore, water nearer shore usually contains more dissolved nutrients than water farther from shore. Q: Aquatic producers need nutrients and what dissolved gas, which is more abundant near the surface of water? Choices: - helium - nitrogen - methane - oxygen A:

Ans:oxygen
Question: Answer the following question given this paragraph: Carbon dioxide is an oxide of carbon, while water is an oxide of hydrogen. Early scientists viewed oxidation as a process in which a substance was reacted with oxygen to produce one or more oxides. In the previous examples, magnesium and methane are being oxidized. Q: Water is an oxide of what element? Choices: - nitrogen - helium - carbon - hydrogen A:
Answer:
hydrogen
