Q: Answer the following question given this paragraph: As Melvin Calvin discovered, carbon fixation is the first step of a cycle. Like an electron transport chain, the Calvin Cycle, shown in Figure below , transfers energy in small, controlled steps. Each step pushes molecules uphill in terms of energy content. Recall that in the electron transfer chain, excited electrons lose energy to NADPH and ATP. In the Calvin Cycle, NADPH and ATP formed in the light reactions lose their stored chemical energy to build glucose. Q: Carbon fixation is the first step of what cycle involving light reactions? A:

OPTIONS:
- sun cycle
- life cycle
- water cycle
- calvin cycle

A: calvin cycle

input: OPTIONS:
- sunlight
- sucrose
- carbon dioxide
- food Now, answer this question: Answer the following question given this paragraph: 15.1 | Features of the Animal Kingdom By the end of this section, you will be able to: List the features that distinguish the animal kingdom from other kingdoms Explain the processes of animal reproduction and embryonic development Describe the hierarchy of basic animal classification Compare and contrast the embryonic development of protostomes and deuterostomes Even though members of the animal kingdom are incredibly diverse, animals share common features that distinguish them from organisms in other kingdoms. All animals are eukaryotic, multicellular organisms, and almost all animals have specialized tissues. Most animals are motile, at least during certain life stages. Animals require a source of food to grow and develop. All animals are heterotrophic, ingesting living or dead organic matter. This form of obtaining energy distinguishes them from autotrophic organisms, such as most plants, which make their own nutrients through photosynthesis and from fungi that digest their food externally. Animals may be carnivores, herbivores, omnivores, or parasites (Figure 15.2). Most animals reproduce sexually: The offspring pass through a series of developmental stages that establish a determined body plan, unlike plants, for example, in which the exact shape of the body is indeterminate. The body plan refers to the shape of an animal. Q: What do animals require to grow and develop? A:
A:
output: food

Answer the following question given this paragraph: Speed may be constant, but often it varies from moment to moment. Speed at any given instant is called instantaneous speed. It is much more difficult to calculate than average speed. Q: What is speed at any given instant called? A:

OPTIONS:
- spontaneous speed
- marginal speed
- relative speed
- instantaneous speed

Answer: instantaneous speed

Problem: OPTIONS:
- heat
- wind
- rain
- gravity
Q: Answer the following question given this paragraph: Hot spots may also be active at plate boundaries. This is especially common at mid-ocean ridges. Iceland is formed by a hot spot along the Mid-Atlantic Ridge. Q: What makes soil and rock particles move gradually down the slope during each thaw? A:
Answer: gravity

Problem:OPTIONS:
- volume fluctuates
- volume decreases

Answer the following question given this paragraph: The volume increases as the temperature increases. The result has three significant figures. Q: What happens to volume as the temperature increases? A:
****
A: volume increases

Problem:OPTIONS:
- adrenaline receptors
