Q: Chloroplasts, leucoplasts and chromoplasts are found in what type of cells? Read this paragraph and choose the correct option from the provided answers: A third difference between plant and animal cells is that plants have several kinds of organelles called plastids . And there are several different kinds of plastids in plant cells. For example, Chloroplasts are needed for photosynthesis, leucoplasts can store starch or oil, and brightly colored chromoplasts give some flowers and fruits their yellow, orange, or red color. It is the presence of chloroplasts and the ability to photosynthesize, that is one of the defining features of a plant. No animal or fungi can photosynthesize, and only some protists are able to. The photosynthetic protists are the plant-like protists, represented mainly by the unicellular algae. Choices: - nitrogen cells - animal cells - man-made cells - plant cells A:
plant cells

Q: Unlike pure substances, mixtures have a what? Read this paragraph and choose the correct option from the provided answers: When two or more pure substances are combined together, a mixture is formed. Unlike pure substances, mixtures have a variable composition. Variable composition indicates that the relative proportions of the mixtures components may vary, and they can be separated by physical methods. There are two main types of mixtures. Choices: - efficient composition - unique composition - complex composition - variable composition A:
(Answer)
variable composition

Q: Why does a large log burn relatively slowly compared to the same mass of wood in the form of small twigs? Read this paragraph and choose the correct option from the provided answers: A large log placed in a fire will burn relatively slowly. If the same mass of wood were added to the fire in the form of small twigs, they would burn much more quickly. This is because the twigs provide a greater surface area than the log does. An increase in the surface area of a reactant increases the rate of a reaction. Surface area is larger when a given amount of a solid is present as smaller particles. A powdered reactant has a greater surface area than the same reactant as a solid chunk. In order to increase the surface area of a substance, it may be ground into smaller particles or dissolved into a liquid. In solution, the dissolved particles are separated from each other and will react more quickly with other reactants. Choices: - smaller blade area - larger surface area - larger surface area - smaller surface area A:
smaller surface area
