Ques: Q: The trade winds are nearest what? Read this paragraph and choose the correct option from the provided answers: The wind belts have names. The Trade Winds are nearest the equator. The next belt is the westerlies. Finally are the polar easterlies. The names are the same in both hemispheres. Choices: - boundary plates - poles - inland - equator A:
Ans: equator

Ques: Q: What happens when a sodium atom loses an electron? Read this paragraph and choose the correct option from the provided answers: By losing an electron, the sodium atom becomes a sodium ion. It now has one less electron than protons, giving it a charge of +1. Positive ions such as sodium are given the same name as the element. The chemical symbol has a plus sign to distinguish the ion from an atom of the element. The symbol for a sodium ion is Na + . Choices: - becomes calcium - gains a proton - combines with hydrogen - becomes sodium ion A:
Ans: becomes sodium ion

Ques: Q: Blood vessels blood pumped by the heart flows through a series of vessels known as arteries, arterioles, capillaries, venules, and veins before returning to this? Read this paragraph and choose the correct option from the provided answers: CHAPTER REVIEW 20.1 Structure and Function of Blood Vessels Blood pumped by the heart flows through a series of vessels known as arteries, arterioles, capillaries, venules, and veins before returning to the heart. Arteries transport blood away from the heart and branch into smaller vessels, forming arterioles. Arterioles distribute blood to capillary beds, the sites of exchange with the body tissues. Capillaries lead back to small vessels known as venules that flow into the larger veins and eventually back to the heart. The arterial system is a relatively high-pressure system, so arteries have thick walls that appear round in cross section. The venous system is a lower-pressure system, containing veins that have larger lumens and thinner walls. They often appear flattened. Arteries, arterioles, venules, and veins are composed of three tunics known as the tunica intima, tunica media, and tunica externa. Capillaries have only a tunica intima layer. The tunica intima is a thin layer composed of a simple squamous epithelium known as endothelium and a small amount of connective tissue. The tunica media is a thicker area composed of variable amounts of smooth muscle and connective tissue. It is the thickest layer in all but the largest arteries. The tunica externa is primarily a layer of connective tissue, although in veins, it also contains some smooth muscle. Blood flow through vessels can be dramatically influenced by vasoconstriction and vasodilation in their walls. Choices: - lungs - feet - brain - heart A:
Ans: heart

Ques: Q: The primary role of leaves is to collect what? Read this paragraph and choose the correct option from the provided answers: Plants have specialized organs that help them survive and reproduce in a great diversity of habitats. Major organs of most plants include roots, stems, and leaves. Leaves are the keys not only to plant life but to all terrestrial life. The primary role of leaves is to collect sunlight and make food by photosynthesis . Despite the fundamental importance of the work they do, there is great diversity in the leaves of plants. However, given the diversity of habitats in which plants live, it's not surprising that there is no single best way to collect solar energy for photosynthesis. Choices: - pollen - insects - precipitation - sunlight A:
Ans:
sunlight
