Q: Answer the following question given this paragraph: Exothermic reactions in organisms are called catabolic reactions . These reactions break down molecules into smaller units and release energy. An example of a catabolic reaction is the breakdown of glucose, which releases energy that cells need to carry out life processes. Endothermic reactions in organisms are called anabolic reactions . These reactions build up bigger molecules from smaller ones. An example of an anabolic reaction is the joining of amino acids to form a protein. Which type of reactionscatabolic or anabolicdo you think occur when your body digests food?. Q: Exothermic reactions in organisms are called what? Choices: - nuclear reactions - nebular reactions - biogenic reactions - catabolic reactions A:
A: catabolic reactions

Q: Answer the following question given this paragraph: Q: What produces gametes with different alleles? Choices: - prokaryotes - anthocyanins - chromatids - heterozygotes A:
A: heterozygotes

Q: Answer the following question given this paragraph: Convex lenses are thicker in the middle than at the edges. They cause rays of light to converge, or meet, at a point called the focus (F). Convex lenses form either real or virtual images. It depends on how close an object is to the lens relative to the focus. Figure below shows how a convex lens works. You can also interact with an animated convex lens at the URL below. An example of a convex lens is a hand lens. Q: Convex lenses are thicker in the middle than at the edges so they cause rays of light to converge, or meet, at a point called what? Choices: - the center - the base - the apex - focus A:
A: focus

Q: Answer the following question given this paragraph: Nitrogen Fixation: Root and Bacteria Interactions Nitrogen is an important macronutrient because it is part of nucleic acids and proteins. Atmospheric nitrogen, which is the diatomic molecule N2, or dinitrogen, is the largest pool of nitrogen in terrestrial ecosystems. However, plants cannot take advantage of this nitrogen because they do not have the necessary enzymes to convert it into biologically useful forms. However, nitrogen can be "fixed," which means that it can be converted to ammonia (NH3) through biological, physical, or chemical processes. As you have learned, biological nitrogen fixation (BNF) is the conversion of atmospheric nitrogen (N2) into ammonia (NH3), exclusively carried out by prokaryotes such as soil bacteria or cyanobacteria. Biological processes contribute 65 percent of the nitrogen used in agriculture. The following equation represents the process:. Q: Nitrogen is an important macronutrient because it is part of nucleic acids and proteins. atmospheric nitrogen, which is the diatomic molecule n2, or dinitrogen, is the largest pool of nitrogen in these? Choices: - gas planets - desert biomes - aquatic ecosytems - terrestrial ecosystems A:
A: terrestrial ecosystems
