Answer the following question given this paragraph: Sponges come in a variety of shapes and sizes. For example, they may be shaped like tubes, fans, cones, or just blobs. They range in diameter from about a centimeter (0.4 inches) to over a meter (3.3 feet). Many species live in colonies that may be quite large. Adult sponges are sessile . This means they are unable to move from place to place. Root-like projections anchor them to solid surfaces such as rocks and reefs. Q: What is it called when something is unable to move from place to place? Choices: - Undrate - obovate - ovate - sessile A:
sessile

Q: What phenomenon is crowding out other species and making all the other causes of extinction worse? Choices: - climate change - human suburbanization - migration - human overpopulation A:
human overpopulation

Answer the following question given this paragraph: Using Lewis Dot Symbols to Describe Covalent Bonding The valence electron configurations of the constituent atoms of a covalent compound are important factors in determining its structure, stoichiometry, and properties. For example, chlorine, with seven valence electrons, is one electron short of an octet. If two chlorine atoms share their unpaired electrons by making a covalent bond and forming Cl2, they can each complete their valence shell:. Q: If two chlorine atoms share their unpaired electrons by making a covalent bond and forming cl2, they can each complete their what? Choices: - hypothesized shell - radiative shell - electron shell - valence shell A:
valence shell
