Q: What is the term for flowering seed plants? Read this paragraph and choose the correct option from the provided answers: Angiosperms , or flowering seed plants, form seeds in ovaries. As the seeds develop, the ovaries may develop into fruits. Flowers attract pollinators, and fruits encourage animals to disperse the seeds. Choices: - spores - perennials - gymnosperms - angiosperms A:
angiosperms

Q: What are mars' moons thought to be? Read this paragraph and choose the correct option from the provided answers: Mars has two moons that are thought to be captured asteroids. Choices: - guerrillas asteroids - new asteriods - common asteriods - captured asteroids A:
captured asteroids

Q: Q: What category of elements are chacterized by their ability to reflect light, called luster, their high electrical and thermal conductivity, their high heat capacity, and their malleability and ductility? Read this paragraph and choose the correct option from the provided answers: Metallic Solids Metals are characterized by their ability to reflect light, called luster, their high electrical and thermal conductivity, their high heat capacity, and their malleability and ductility. Every lattice point in a pure metallic element is occupied by an atom of the same metal. The packing efficiency in metallic crystals tends to be high, so the resulting metallic solids are dense, with each atom having as many as 12 nearest neighbors. Bonding in metallic solids is quite different from the bonding in the other kinds of solids we have discussed. Because all the atoms are the same, there can be no ionic bonding, yet metals always contain too few electrons or valence orbitals to form covalent bonds with each of their neighbors. Instead, the valence electrons are delocalized throughout the crystal, providing a strong cohesive force that holds the metal atoms together. Choices: - halogens - nonmetals - noble gases - metals A:
A: metals

Question: Q: Amphibians have permeable skin which allows for the exchange of oxygen and carbon dioxide, what is this "breathing called?" Read this paragraph and choose the correct option from the provided answers: Characteristics of Amphibians As tetrapods, most amphibians are characterized by four well-developed limbs. Some species of salamanders and all caecilians are functionally limbless; their limbs are vestigial. An important characteristic of extant amphibians is a moist, permeable skin that is achieved via mucus glands that keep the skin moist; thus, exchange of oxygen and carbon dioxide with the environment can take place through it ( cutaneous respiration). Additional characteristics of amphibians include pedicellate teethteeth in which the root and crown are calcified, separated by a zone of noncalcified tissueand a papilla amphibiorum and papilla basilaris, structures of the inner ear that are sensitive to frequencies below and above 10,00 hertz, respectively. Amphibians also have an auricular operculum, which is an extra bone in the ear that transmits sounds to the inner ear. All extant adult amphibians are carnivorous, and some terrestrial amphibians have a sticky tongue that is used to capture prey. Choices: - variant respiration - benign respiration - aquatic respiration - cutaneous respiration A:
Answer: cutaneous respiration

Q: In what type of process does heat flow into its surroundings and cause an increase in kinetic energy? Read this paragraph and choose the correct option from the provided answers: In general, the process of interest is taking place in the system, and there are no changes in the composition of the surroundings. However, the temperature of the surroundings does generally change. Entropy changes in the surroundings are determined primarily by the flow of heat into or out of the system. In an exothermic process, heat flows into the surroundings, increasing the kinetic energy of the nearby particles. For an exothermic reaction, S surr is positive. Conversely, heat flows from the surroundings into the system during an endothermic process, lowering the kinetic energy available to the surroundings and resulting in a negative value for S surr . Choices: - biochemical process - chemical process - oscillating process - exothermic process A:
**Answer**
exothermic process

Q: What substances are involved in most of the chemical reactions that take place in organisms, including digestion? Read this paragraph and choose the correct option from the provided answers: Enzymes are involved in most of the chemical reactions that take place in organisms. About 4,000 such reactions are known to be catalyzed by enzymes, but the number may be even higher. In animals, an important function of enzymes is to help digest food. Digestive enzymes speed up reactions that break down large molecules of carbohydrates, proteins, and fats into smaller molecules the body can use. Without digestive enzymes, animals would not be able to break down food molecules quickly enough to provide the energy and nutrients they need to survive. Choices: - proteins - hormones - vitamins - enzymes A:
(A).
enzymes
