Answer the following question given this paragraph: In plants, most chloroplasts are found in the leaves. Therefore, all the raw materials needed for photosynthesis must be present in the leaves. These materials include light, water, and carbon dioxide. The shape of the leaves gives them a lot of surface area to absorb light for photosynthesis. Roots take up water from the soil. Stems carry the water from the roots to the leaves. Carbon dioxide enters the leaves through tiny openings called stomata. (The oxygen released during photosynthesis also exits the leaves through the stomata. ). Q: Where are most chloroplasts found in plants? Choices: - roots - stems - flowers - leaves A:
leaves

Answer the following question given this paragraph: The top 200 meters of water is the photic zone. Producers here include seaweeds and phytoplankton. Other organisms are plentiful. They include zooplankton and animals such as fish, whales, and dolphins. Q: The top 200 meters of water is called what zone? Choices: - the subterranean zone - the biotic zone - the stratosphere - the photic zone A:
(Answer)
the photic zone
Ques: Answer the following question given this paragraph: Herbivory has been used by seed plants for their own benefit in a display of mutualistic relationships. The dispersal of fruit by animals is the most striking example. The plant offers to the herbivore a nutritious source of food in return for spreading the plant's genetic material to a wider area. An extreme example of collaboration between an animal and a plant is the case of acacia trees and ants. The trees support the insects with shelter and food. In return, ants discourage herbivores, both invertebrates and vertebrates, by stinging and attacking leaf-eating insects. Q: How do seed plants benefit from herbivores? Choices: - radiation of seeds - consumption of seeds - rainfall of seeds - dispersal of seeds A:
Ans: dispersal of seeds
(Q).
Answer the following question given this paragraph: An element, as defined in Chapter 1 "Chemistry, Matter, and Measurement", is a substance that cannot be broken down into simpler chemical substances. There are about 90 naturally occurring elements known on Earth. Using technology, scientists have been able to create nearly 30 additional elements that do not occur in nature. Today, chemistry recognizes 118 elementssome of which were created an atom at a time. Figure 2.1 "Samples of Elements" shows some of the chemical elements. Q: How many naturally occurring elements are known on earth? Choices: - 85 - 60 - 87 - 90 A:
(A).
90
Ques:Answer the following question given this paragraph: The fluffy white fibers on this plant look like cotton balls because that's what they are. The plant is a cotton plant, and the fibers are used to make cotton fabric. Cotton fibers consist of one of the most common compounds on Earth: cellulose. Cellulose is a biochemical compound found in all plants. It belongs to the class of biochemical compounds called carbohydrates. Q: What is one of the most common biochemical compounds on earth and is found in all plants? Choices: - carbon dioxide - hydrogen - sulfur - cellulose A:

Ans:cellulose
Question: Answer the following question given this paragraph: enzymes - proteins which speed up chemical reactions. Q: Enzymes - proteins which speed up what? Choices: - crystals reactions - liquid reactions - physical reactions - chemical reactions A:
Answer:
chemical reactions
