Q: What is the attraction of oppositely charged ions caused by electron transfer called? Read this paragraph and choose the correct option from the provided answers: The attraction of oppositely charged ions caused by electron transfer is called an ionic bond. Choices: - covalent bond - velocity bond - solvent bond - ionic bond A:
ionic bond

Q: What type of tissue transports water, nutrients, and food in plants? Read this paragraph and choose the correct option from the provided answers: A later adaption for life on land was the evolution of vascular tissue. Vascular tissue is specialized tissue that transports water, nutrients, and food in plants. In algae, vascular tissue is not necessary since the entire body is in contact with the water, and the water simply enters the algae. But on land, water may only be found deep in the ground. Vascular tissues take water and nutrients from the ground up into the plant, while also taking food down from the leaves into the rest of the plant. The two vascular tissues are xylem and phloem. Xylem is responsible for the transport of water and nutrients from the roots to the rest of the plant. Phloem carries the sugars made in the leaves to the parts of the plant where they are needed. Choices: - rough tissue - normal tissue - smooth tissue - vascular tissue A:
vascular tissue

Q: Q: Helicopters store large amounts of rotational energy of what type in their blades? Read this paragraph and choose the correct option from the provided answers: Figure 10.18 The first image shows how helicopters store large amounts of rotational kinetic energy in their blades. This energy must be put into the blades before takeoff and maintained until the end of the flight. The engines do not have enough power to simultaneously provide lift and put significant rotational energy into the blades. The second image shows a helicopter from the Auckland Westpac Rescue Helicopter Service. Over 50,000 lives have been saved since its operations beginning in 1973. Here, a water rescue operation is shown. (credit: 111 Emergency, Flickr). Choices: - magnetic - seismic - thermal - kinetic A:
A: kinetic

Question: Q: What will the contraction of smooth muscles help organs do? Read this paragraph and choose the correct option from the provided answers: Muscle tissue in the walls of internal organs such as the stomach and intestines is smooth muscle . When smooth muscle contracts, it helps the organs carry out their functions. For example, when smooth muscle in the stomach contracts, it squeezes the food inside the stomach, which helps break the food into smaller pieces. Contractions of smooth muscle are involuntary. This means they are not under conscious control. Choices: - fine motor movements - move joints - move across distances - carry out functions A:
Answer: carry out functions

*Question*
Q: What is the name for the pores in leaves that allow a plant to retain water or exchange gases? Read this paragraph and choose the correct option from the provided answers: To allow the plant to retain water and exchange gases, small pores (holes) in the leaves called stomata also evolved ( Figure below ). The stomata can open and close depending on weather conditions. When it's hot and dry, the stomata close to keep water inside of the plant. When the weather cools down, the stomata can open again to let carbon dioxide in and oxygen out. Choices: - neurons - chloroplasts - rhizomes - stomata A:
**Answer**
stomata

Q: The two stages of photosynthesis are the light reactions and what? Read this paragraph and choose the correct option from the provided answers: The two stages of photosynthesis are the light reactions and the Calvin cycle. Do you see how the two stages are related?. Choices: - digestive cycle - respiratory cycle - reproductive cycle - calvin cycle A:
calvin cycle
