Answer the following question given this paragraph: Each kind of pigment absorbs specific wavelengths (colors) of light (dashed lines). Sunlight contains many different wavelengths, which you see when they separate into a rainbow. Not all colors of light are used in photosynthesis (solid line). Most plants, algae, and photosynthetic bacteria appear green because they reflect green wavelengths. Their pigments have absorbed the violet-blue and red wavelengths. The amount of photosynthesis depends on the wavelength of light available. Beta-carotene is another type of pigment that absorbs sunlight. Q: Sunlight contains many different wavelengths, which you see when they separate into what? Choices: - shadows - charges - sounds - rainbow A:
rainbow

Answer the following question given this paragraph: So what happens to your body's wastes? Obviously, you must get rid of them. This is the job of the excretory system. You remove waste as a gas (carbon dioxide), as a liquid (urine and sweat), and as a solid. Excretion is the process of removing wastes and excess water from the body. Q: What body system gets rid of waste? Choices: - digestive system - Muscular system - nervous system - excretory system A:
(Answer)
excretory system
Ques: Answer the following question given this paragraph: The hypothalamus also produces hormones that directly regulate body processes. For example, it produces antidiuretic hormone. This hormone travels to the kidneys and stimulates them to conserve water by producing more concentrated urine. Q: What produces hormones that directly regulate body processes? Choices: - hippocampus - lymph glands - pancreas - hypothalamus A:
Ans: hypothalamus
(Q).
Answer the following question given this paragraph: Compounds like sodium chloride form structures called crystals. A crystal is a rigid framework of many ions locked together in a repeating pattern. Ions are electrically charged forms of atoms. You can see a crystal of sodium chloride in the Figure below . It is made up of many sodium and chloride ions. Q: Compounds like sodium chloride form structures called what? Choices: - ions - microorganisms - hydrocarbons - crystals A:
(A).
crystals
Ques:Answer the following question given this paragraph: There are many different types of symbiotic interactions between organisms. Clockwise from top left: Escherichia coli bacteria live inside your intestines in a mutualistic relationship: the bacteria produce Vitamin K for you, and they get their food from what you eat. Clownfish that live among the tentacles of sea anemones protect the anemone from anemone-eating fish, and in turn the stinging tentacles of the anemone protect the clownfish from its predators (a special mucus on the clownfish protects it from the stinging tentacles). Similar to the E. coli , this bee has a mutualistic relationship with the flower, the bee feeds from the flower, and the flower gets pollinated by the bee. Lions are predators that feed on other organisms such as this Cape buffalo. Q: In what part of the body do escherichia coli bacteria live? Choices: - your brain - your kidneys - your urethra - your intestines A:

Ans:your intestines
Ques: Answer the following question given this paragraph: Ionic compounds are compounds in which positive metal ions and negative nonmetal ions are joined by ionic bonds. In these compounds, the chemical symbol for the positive metal ion is written first, followed by the symbol for the negative nonmetal ion. The video at the following URL gives a fuller explanation of ionic compounds and their formulas: http://www. youtube. com/watch?v=vscoYh6m46M . Q: The chemical symbol of which ion is written first in ionic compounds? Choices: - negative ion - good metal ion - last ion - positive metal ion A:
Ans:
positive metal ion
