Answer the following question given this paragraph: An ionic bond is the force of attraction that holds together positive and negative ions. It forms when atoms of a metallic element give up electrons to atoms of a nonmetallic element. Figure below shows how this happens. Q: What bond is the force of attraction that holds together positive and negative ions? Choices: - Protonic - Electric - magnetic - ionic A:
(Answer)
ionic
Ques: Answer the following question given this paragraph: As living things evolve, they generally become better suited for their environment. This is because they evolve adaptations. An adaptation is a characteristic that helps a living thing survive and reproduce in a given environment. Look at the mole in Figure below . It has tentacles around its nose that it uses to sense things by touch. The mole lives underground in the soil where it is always dark. However, by using its touch organ, it can detect even tiny food items in the soil in total darkness. The touch organ is an adaptation because it helps the mole survive in its dark, underground environment. Q: Living things evolve what characteristics that make them better suited for their environment? Choices: - mutations - instincts - reflexes - adaptations A:
Ans: adaptations

Ques:Answer the following question given this paragraph: 4.2 Prokaryotic Cells Prokaryotes are predominantly single-celled organisms of the domains Bacteria and Archaea. All prokaryotes have plasma membranes, cytoplasm, ribosomes, and DNA that is not membrane-bound. Most have peptidoglycan cell walls and many have polysaccharide capsules. Prokaryotic cells range in diameter from 0.1 to 5.0 m. As a cell increases in size, its surface area-to-volume ratio decreases. If the cell grows too large, the plasma membrane will not have sufficient surface area to support the rate of diffusion required for the increased volume. Q: As the prokaryotic cell size increases, what happens to its surface area-to-volume ratio? Choices: - stagnates - halts - increases - decreases A:

Ans:decreases
