Q: Answer the following question given this paragraph: Recall that eukaryotic organisms also include animals, protists, and fungi. Eukaryotes have cells with nuclei that contain DNA, and membrane-bound organelles, such as mitochondria. Photosynthesis is the process by which plants capture the energy of sunlight and use carbon dioxide from the air (and water) to make their own food, the carbohydrate glucose. Plants have chloroplasts, the organelle of photosynthesis, and are known as producers and autotrophs. Other organisms are heterotrophic consumers, meaning they must obtain their nutrients from another organism, as these organisms lack chloroplasts. Lastly, plants must be multicellular, composed of more than one cell. There are no single-celled plants. Recall that some protists, such as algae, are eukaryotic and photosynthetic but are not considered plants. Unlike plants, algae is mostly unicellular. Q: What is the process by which plants capture the energy of sunlight and use carbon dioxide from the air (and water) to make their own food called? Choices: - spermatogenesis - photochemistry - atherosclerosis - photosynthesis A:
A: photosynthesis

Q: Answer the following question given this paragraph: Precision describes how close estimates are to one another. Estimates that are relatively close to one another are precise. Let's assume that ten different students made an estimate of the volume shown in Figure above , and the values were: 52.9, 52.8, 52.9, 52.9, 53.3, 52.0, 52.8, 52.9, 53.0, 52.8. We can determine how precise these data by analyzing how close they are to an average. The average could be the mean, median or mode. The most common understanding of the average is the mean. This value is calculated by adding up all the numbers and then dividing by the total number of values. Other terms that can refer to the average are the median and the mode. The median is the middle value in a numerically ordered list of numbers. The mode is the value that occurs most often in a set of numbers. If no number is repeated, there is no mode for the list. Here are the calculated averages:. Q: What term describes how close estimates are to one another? Choices: - precise - Distant - efficiency - precision A:
A: precision

Q: Answer the following question given this paragraph: Lysosomes, which use enzymes to break down foreign matter and dead cells. Q: What use enzymes to break down foreign matter and dead cells? Choices: - lipids - hormones - lymphocytes - lysosomes A:
A: lysosomes

Q: Answer the following question given this paragraph: Mutations are essential for evolution to occur because they increase genetic variation and the potential for individuals to differ. The majority of mutations are neutral in their effects on the organisms in which they occur. Beneficial mutations may become more common through natural selection. Harmful mutations may cause genetic disorders or cancer. Q: What phenomenon is essential in order for evolution to occur because it increases genetic variation and the potential for individuals to differ? Choices: - radiation - replication - natural selection - mutation A:
A: mutation
