Answer the following question given this paragraph: The human eye can distinguish only red, green, and blue light. These three colors are the primary colors of light. All other colors of light can be created by combining the primary colors. Secondary colors of lightcyan, yellow, and magentaform when two primary colors combine equally. Q: What three primary colors of light can be distinguished by the human eye? Choices: - blue, red, orange - yellow, green, blue - red, green, yellow - red, green, blue A:
red, green, blue
Answer the following question given this paragraph: Minerals can form various shapes. Polygons are pictured below ( Figure below ). The shapes form as the minerals are broken along their cleavage planes. Cleavage planes determine how the crystals can be cut to make smooth surfaces. People who cut gemstones follow cleavage planes. Diamonds and emeralds can be cut to make beautiful gemstones. Q: The shapes of minerals form as they are broken along what planes? Choices: - parallel planes - sedimentary planes - calcium planes - cleavage planes A:
cleavage planes
Q: Answer the following question given this paragraph: The respiratory system is the body system that exchanges gases with the outside air. It brings air containing oxygen into the body for the cells. It also releases carbon dioxide from the cells into the air. This exchange of gases is called respiration. Q: Which system in the body exchanges gases with the outside air? Choices: - immune - digestive - vascular - respiratory A:
A: respiratory
Question: Answer the following question given this paragraph: The energy that the object gains or loses when traveling through a potential difference is supplied (or absorbed) by the electric field --- there is nothing else there. Therefore, it follows that electric fields contain energy . Q: Where does an object gain or lose it's energy to during travel through a potential difference? Choices: - particle field - magnetic field - wave field - electric field A:
Answer: electric field

Answer the following question given this paragraph: The mouth also begins the process of mechanical digestion . Sharp teeth in the front of the mouth cut or tear food when you bite into it (see Figure below ). Broad teeth in the back of the mouth grind food when you chew. Food is easier to chew because it is moistened by saliva from the salivary glands. The tongue helps mix the food with saliva and also helps you swallow. After you swallow, the chewed food passes into the pharynx. Q: Where does mechanical digestion begin? Choices: - intestines - brain - stomach - mouth A:
**Answer**
mouth
Q: Answer the following question given this paragraph: The Heart The heart is a complex muscle that consists of two pumps: one that pumps blood through pulmonary circulation to the lungs, and the other that pumps blood through systemic circulation to the rest of the body's tissues (and the heart itself). The heart is asymmetrical, with the left side being larger than the right side, correlating with the different sizes of the pulmonary and systemic circuits (Figure 16.10). In humans, the heart is about the size of a clenched fist; it is divided into four chambers: two atria and two ventricles. There is one atrium and one ventricle on the right side and one atrium and one ventricle on the left side. The right atrium receives deoxygenated blood from the systemic circulation through the major veins: the superior vena cava, which drains blood from the head and from the veins that come from the arms, as well as the inferior vena cava, which drains blood from the veins that come from the lower organs and the legs. This deoxygenated blood then passes to the right ventricle through the tricuspid valve, which prevents the backflow of blood. After it is filled, the right ventricle contracts, pumping the blood to the lungs for reoxygenation. The left atrium receives the oxygen-rich blood from the lungs. This blood passes through the bicuspid valve to the left ventricle where the blood is pumped into the aorta. The aorta is the major artery of the body, taking oxygenated blood to the organs and muscles of the body. This pattern of pumping is referred to as double circulation and is found in all mammals. (Figure 16.10). Q: What is the major artery of the body, taking oxygenated blood to the organs and muscles of the body? Choices: - carotid - capillary - diastolic - aorta A:
A: aorta
