(Q).
Answer the following question given this paragraph: All living things reproduce to make the next generation. Organisms that do not reproduce will go extinct. As a result, there are no species that do not reproduce ( Figure below ). Some organisms reproduce asexually ( asexual reproduction ), especially single-celled organisms, and make identical copies (or clones) of themselves. Other organisms reproduce sexually ( sexual reproduction ), combining genetic information from two parents to make genetically unique offspring. Q: What process do all species use to make the next generation? Choices: - separation - differentiation - variation - reproduction A:
(A).
reproduction

(Q).
Answer the following question given this paragraph: Birds also have wings that function as an aerofoil . The surface of the aerofoil is curved to help the bird control and use the air currents to fly. Aerofoils are also found on the wings of airplanes. Q: Where are aerofoils found? Choices: - airplanes and plants - birds and busses - birds and cars - birds and airplanes A:
(A).
birds and airplanes

(Q).
Answer the following question given this paragraph: Blood vessels help regulate body processes by either constricting (becoming narrower) or dilating (becoming wider). These actions occur in response to signals from the autonomic nervous system or the endocrine system. Constriction occurs when the muscular walls of blood vessels contract. This reduces the amount of blood that can flow through the vessels (see Figure below ). Dilation occurs when the walls relax. This increases blood flows through the vessels. Q: What structures of the cardiovascular system help regulate body processes by either constricting or dilating? Choices: - muscles - cartilage - capillaries - blood vessels A:
(A).
blood vessels
