Q: Q: If both atoms are the same, they have the same electronegativity and share what type of bond? Read this paragraph and choose the correct option from the provided answers: Choices: - metabolic - ionic - isotopic covalent - nonpolar covalent A:
A: nonpolar covalent

Q: Q: What are the three most common elements in the air we breathe? Read this paragraph and choose the correct option from the provided answers: Most nonmetals are poor conductors of heat. In fact, they are such poor conductors of heat that they are often used for insulation. For example, the down filling in this sleeping bag is full of air, which consists primarily of the nonmetal gases oxygen and nitrogen. These gases prevent body heat from escaping to the cold outside air. Choices: - oxygen, nitrogen, H20 - nitrogen, argon, hydrogen - argon, oxygen, hydrogen - nitrogen, oxygen and argon A:
A: nitrogen, oxygen and argon

Q: Q: What is the area around the nucleus of an atom where electrons are likely to be, called? Read this paragraph and choose the correct option from the provided answers: Today, these ideas about electrons are represented by the electron cloud model. The electron cloud is an area around the nucleus where electrons are likely to be. Figure below shows an electron cloud model for a helium atom. Choices: - electron wave - electron membrane - electron pocket - electron cloud A:
A: electron cloud

Q: Q: What broad category of animals is primarily ectothermic and covered with scales that facilitate swimming? Read this paragraph and choose the correct option from the provided answers: Fish show great diversity in body size. They range in length from about 8 millimeters (0.3 inches) to 16 meters (about 53 feet). Most are ectothermic and covered with scales. Scales protect fish from predators and parasites and reduce friction with the water. Multiple, overlapping scales provide a flexible covering that allows fish to move easily while swimming. Choices: - armadillo - turtles - deer - fish A:
A: fish
