Q: Clams, oysters, scallops, and mussels are examples of what type of species? Read this paragraph and choose the correct option from the provided answers: Mollusks live in most terrestrial, freshwater, and marine habitats. However, the majority of species live in the ocean. They can be found in both shallow and deep water and from tropical to polar latitudes. Mollusks are a major food source for other organisms, including humans. You may have eaten mollusks such as clams, oysters, scallops, or mussels. Choices: - mammals - invertebrates - tortoises - mollusks A:
mollusks

Q: A binary molecular compound is a molecular compound that is composed of what? Read this paragraph and choose the correct option from the provided answers: A binary molecular compound is a molecular compound that is composed of two elements. In general, the elements that combine to form binary molecular compounds are both nonmetals. This contrasts with ionic compounds, which usually involve bonds between metal ions and nonmetal ions. Because ionic charges cannot be used to name these compounds or to write their formulas, a different naming system must be used for molecular compounds. Another difference between ionic and molecular compounds is that two nonmetal atoms will frequently combine with one another in a variety of ratios. For example, nitrogen and oxygen combine to make several binary compounds, including NO, NO 2 , and N 2 O. Obviously they can't all be called nitrogen oxide! How would someone know which one you were talking about? Each of the three compounds has very different properties and reactivity. A system to distinguish between compounds such as these is necessary. Choices: - two atoms - four atoms - four elements - two elements A:
two elements

Q: Anything that occupies space and has mass is known as what? Read this paragraph and choose the correct option from the provided answers: All living things are made of matter . In fact, matter is the "stuff" of which all organisms are made. Anything that occupies space and has mass is known as matter. Matter, in turn, consists of chemical substances. It is the carbons, hydrogens, oxygens and other elements that combine to form molecules, compounds, organelles, cells and eventually tissues, organs and organisms. In addition to being made of matter, all living organisms also need energy to survive. Choices: - opaque - solid - dense - matter A:
matter

Q: Cellular respiration in humans involves the combustion of what simple sugar? Read this paragraph and choose the correct option from the provided answers: Your own body cells burn fuel in combustion reactions. The fuel is glucose (C 6 H 12 O 6 ), a simple sugar. The process in which combustion of glucose occurs in body cells is called cellular respiration. This combustion reaction provides energy for life processes. Cellular respiration can be summed up by the equation:. Choices: - starch - glutamate - insulin - glucose A:
glucose
