Q: What is the term for a fold that arches upward? Read this paragraph and choose the correct option from the provided answers: An anticline is a fold that arches upward. The rocks dip away from the center of the fold ( Figure below ). The oldest rocks are found at the center of an anticline. The youngest rocks are draped over them at the top of the structure. When upward folding rocks form a circular structure, that structure is called a dome . If the top of the dome is eroded off, the oldest rocks are exposed at the center. Choices: - tailslide - underlain - tailplane - anticline A:
anticline

Q: A statement that describes what always happens under certain conditions in nature is also known as what? Read this paragraph and choose the correct option from the provided answers: Scientists think of nature as a single system controlled by natural laws. Scientists strive to increase their understanding of the natural world by discovering natural laws. Laws of nature are expressed as scientific laws. A scientific law is a statement that describes what always happens under certain conditions in nature. Choices: - theory - hypothesis - scientific motion - scientific law A:
scientific law

Q: Q: A heterogeneous mixture of particles of one substance distributed throughout a second substance in a different phase is known as what? Read this paragraph and choose the correct option from the provided answers: Summary A suspension is a heterogeneous mixture of particles of one substance distributed throughout a second phase; the dispersed particles separate from the dispersing phase on standing. In contrast, the particles in a colloid are smaller and do not separate on standing. A colloid can be classified as a sol, a dispersion of solid particles in a liquid or solid; a gel, a semisolid sol in which all of the liquid phase has been absorbed by the solid particles; an aerosol, a dispersion of solid or liquid particles in a gas; or an emulsion, a dispersion of one liquid phase in another. A colloid can be distinguished from a true solution by its ability to scatter a beam of light, known as the Tyndall effect. Hydrophilic colloids contain an outer shell of groups that interact favorably with water, whereas hydrophobic colloids have an outer surface with little affinity for water. Emulsions are prepared by dispersing a hydrophobic liquid in water. In the absence of a dispersed hydrophobic liquid phase, solutions of detergents in water form organized spherical aggregates calledmicelles. Phospholipids are a class of detergent-like molecules that have two Saylor URL: http://www. saylor. org/books. Choices: - disruption - solution - fluid - suspension A:
A: suspension

Question: Q: Passive immunity arises from the transfer of what to an individual, without requiring them to mount their own active immune response? Read this paragraph and choose the correct option from the provided answers: Passive immunity arises from the transfer of antibodies to an individual without requiring them to mount their own active immune response. Naturally acquired passive immunity is seen during fetal development. IgG is transferred from the maternal circulation to the fetus via the placenta, protecting the fetus from infection and protecting the newborn for the first few months of its life. As already stated, a newborn benefits from the IgA antibodies it obtains from milk during breastfeeding. The fetus and newborn thus benefit from the immunological memory of the mother to the pathogens to which she has been exposed. In medicine, artificially acquired passive immunity usually involves injections of immunoglobulins, taken from animals previously exposed to a specific pathogen. This treatment is a fast-acting method of temporarily protecting an individual who was possibly exposed to a pathogen. The downside to both types of passive immunity is the lack of the development of immunological memory. Once the antibodies are transferred, they are effective for only a limited time before they degrade. Choices: - parasites - bacteria - viruses - antibodies A:
Answer: antibodies

Q: What kind of energy comes from the position of a charged particle in an electric field? Read this paragraph and choose the correct option from the provided answers: Electric potential energy comes from the position of a charged particle in an electric field. For example, when two negative charges are close together, they have potential energy because they repel each other and have the potential to push apart. If the charges actually move apart, their potential energy decreases. Electric charges always move spontaneously from a position where they have higher potential energy to a position where they have lower potential energy. This is like water falling over a dam from an area of higher to lower potential energy due to gravity. Choices: - solar energy - mechanical energy - thermal energy - potential energy A:
**Answer**
potential energy

Q: When your body digests food, it breaks down the molecules of nutrients and releases what? Read this paragraph and choose the correct option from the provided answers: Carbohydrates, proteins, and lipids contain energy. When your body digests food, it breaks down the molecules of these nutrients. This releases the energy so your body can use it. Choices: - waste materials - gas - calories - energy A:
(Answer)
energy
