Answer the following question given this paragraph: Lines of latitude circle around Earth. The Equator is a line of latitude right in the middle of the planet. Latitude is divided into degrees: 90 north of the Equator and 90 south of the Equator. One degree is subdivided into 60 minutes. One minute is subdivided into 60 seconds. The Equator is at 0. The Equator is an equal distance from both the North and South Poles. If you know your latitude, you know how far you are north or south of the Equator. Q: What line of latitude is an equal distance from both the north and south poles? Choices: - divider - meridian - mid-part - equator A:
equator
Answer the following question given this paragraph: Q: Within a bud, what is spaced close together because the internodes are very short? Choices: - chordae - roots - stems - leaves A:
leaves
Q: Answer the following question given this paragraph: Q: Over many generations, the resulting genetic diversity provides valuable raw material for what? Choices: - coral selection - characteristic selection - intelligent selection - natural selection A:
A: natural selection
Question: Answer the following question given this paragraph: Vacuoles are membrane-bound organelles that can have secretory, excretory, and storage functions. Vacuoles are usually much larger than vesicles. Many organisms will use vacuoles as storage areas and some plant cells have very large vacuoles. The large central vacuole of the plant cell is used for osmotic control (storage of water) and nutrient storage. Contractile vacuoles are found in certain protists. These vacuoles take water from the cytoplasm and excrete it from the cell to avoid bursting due to osmotic pressure. Q: These vacuoles take water from the cytoplasm and excrete it from the cell to avoid bursting due to what? Choices: - apoptotic pressure - static pressure - impervious pressure - osmotic pressure A:
Answer: osmotic pressure

Answer the following question given this paragraph: All living things need energy. Most ecosystems get energy from the Sun. Producers use the energy to make food. They pass some of the energy to consumers. Food chains and food webs show how energy flows through ecosystems. Q: All living things require what, which most ecosystems obtain from the sun? Choices: - oxygen - water - heat - energy A:
**Answer**
energy
Q: 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
