Q: What is the name for creatures such as bears and humans that eat both consumers and producers? Read this paragraph and choose the correct option from the provided answers: Omnivores eat both producers and consumers. Most people are omnivores, since they eat fruits, vegetables, and grains from plants, and also meat and dairy products from animals. Dogs, bears, and raccoons are also omnivores. Choices: - carnivorous - paleo diet - insectivores - omnivores A:
(A).
omnivores

Q: Ionic, covalent, and hydrogen are three important types of what type of interaction between different types of atoms? Read this paragraph and choose the correct option from the provided answers: 2.2 | Chemical Bonds By the end of this section, you will be able to: Explain the relationship between molecules and compounds Distinguish between ions, cations, and anions Identify the key difference between ionic and covalent bonds Distinguish between nonpolar and polar covalent bonds Explain how water molecules link via hydrogen bonds Atoms separated by a great distance cannot link; rather, they must come close enough for the electrons in their valence shells to interact. But do atoms ever actually touch one another? Most physicists would say no, because the negatively charged electrons in their valence shells repel one another. No force within the human bodyor anywhere in the natural worldis strong enough to overcome this electrical repulsion. So when you read about atoms linking together or colliding, bear in mind that the atoms are not merging in a physical sense. Instead, atoms link by forming a chemical bond. A bond is a weak or strong electrical attraction that holds atoms in the same vicinity. The new grouping is typically more stableless likely to react againthan its component atoms were when they were separate. A more or less stable grouping of two or more atoms held together by chemical bonds is called a molecule. The bonded atoms may be of the same element, as in the case of H2, which is called molecular hydrogen or hydrogen gas. When a molecule is made up of two or more atoms of different elements, it is called a chemical compound. Thus, a unit of water, or H2O, is a compound, as is a single molecule of the gas methane, or CH4. Three types of chemical bonds are important in human physiology, because they hold together substances that are used by the body for critical aspects of homeostasis, signaling, and energy production, to name just a few important processes. These are ionic bonds, covalent bonds, and hydrogen bonds. Choices: - forms - conflicts - levels - bonds A:
(A).

Q: The cycle of copper reacting is a good example of what principle? Read this paragraph and choose the correct option from the provided answers: A series of chemical reactions where an initial amount of copper reacts with nitric acid, goes into solution, and disappears. Then a series of reactions proceed, only to have the copper metal recovered. The copper cycle is a good illustration of how mass is conserved in a given chemical reaction. Choices: - law of inertia - conservation of energy - conservation of momentum - conservation of mass A:
(A).
conservation of mass
