Q: Answer the following question given this paragraph: When ancient plants underwent photosynthesis, they changed energy in sunlight to stored chemical energy in food. The plants used the food and so did the organisms that ate the plants. After the plants and other organisms died, their remains gradually changed to fossil fuels as they were covered and compressed by layers of sediments. Petroleum and natural gas formed from ocean organisms and are found together. Coal formed from giant tree ferns and other swamp plants. Q: During photosynthesis what organelle is used by plants to change sunlight into chemical energy? Choices: - mitochondria - golgi apparatus - ribosome - chloroplasts A:
A: chloroplasts

Q: Answer the following question given this paragraph: The cell wall is located outside the cell membrane. It consists mainly of cellulose and may also contain lignin, which makes it more rigid. The cell wall shapes, supports, and protects the cell. It prevents the cell from absorbing too much water and bursting. It also keeps large, damaging molecules out of the cell. Q: Where is the cell wall located? Choices: - in cell membrane - in the chloroplast - in the mitochondria - outside cell membrane A:
A: outside cell membrane

Q: Answer the following question given this paragraph: In some countries, birth rates have fallen even lower than death rates. As result, their population growth rates are negative. In other words, the populations are shrinking in size. These populations have top-heavy population pyramids, like the one for Italy shown in Figure below . This is a new stage of the demographic transition, referred to as Stage 5. You might think that a negative growth rate would be a good thing. In fact, it may cause problems. For example, growth-dependent industries decline. Supporting the large aging population is also a burden for the shrinking younger population of workers. Q: What results when birth rates fall even lower than death rates? Choices: - disease - mutation - increased growth rate - negative growth rate A:
A: negative growth rate

Q: Answer the following question given this paragraph: Extending from the upper corners of the uterus are the two fallopian tubes . Each tube reaches (but is not attached to) one of the ovaries. The ovary end of the tube has a fringelike structure that moves in waves. The motion sweeps eggs from the ovary into the tube. Q: What two tubes extend from the upper corners of the uterus? Choices: - Cervical - ovarian - ovary - fallopian A:
A: fallopian
