Answer the following question given this paragraph: The structure of a chloroplast is shown in Figure below . The chloroplast is surrounded by two membranes. Inside the chloroplast are stacks of flattened sacs of membrane, called thylakoids . The thylakoids contain chlorophyll. Surrounding the thylakoids is a space called the stroma . The stroma is filled with watery ("aqueous") fluid. Q: Thylakoids in a chloroplast contain what plant pigment? Choices: - melanin - dye - ultramarine - chlorophyll A:
chlorophyll

Answer the following question given this paragraph: A major advantage of aerobic respiration is the amount of energy it releases. Without oxygen, organisms can split glucose into just two molecules of pyruvate. This releases only enough energy to make two ATP molecules. With oxygen, organisms can break down glucose all the way to carbon dioxide. This releases enough energy to produce up to 38 ATP molecules. Thus, aerobic respiration releases much more energy than anaerobic respiration. Q: What type of respiration has the advantage of releasing more energy? Choices: - kinetic - anaerobic - elastic - aerobic A:
(Answer)
aerobic
Ques: Answer the following question given this paragraph: Photosynthesis occurs in two stages, called the light reactions and the Calvin cycle. Figure below sums up what happens in these two stages. Both stages are described below. Q: The calvin cycle and light reactions are the two stages of what process? Choices: - condensation - evaporation - cell growth - photosynthesis A:
Ans: photosynthesis

Answer the following question given this paragraph: Figure 35.7 Glial cells support neurons and maintain their environment. Glial cells of the (a) central nervous system include oligodendrocytes, astrocytes, ependymal cells, and microglial cells. Oligodendrocytes form the myelin sheath around axons. Astrocytes provide nutrients to neurons, maintain their extracellular environment, and provide structural support. Microglia scavenge pathogens and dead cells. Ependymal cells produce cerebrospinal fluid that cushions the neurons. Glial cells of the (b) peripheral nervous system include Schwann cells, which form the myelin sheath, and satellite cells, which provide nutrients and structural support to neurons. Q: What is a type of cell that supports neurons and maintains their environment? Choices: - axon cell - neurofilament cell - interneuron cell - glial cell A:
(A).
glial cell
Ques:Answer the following question given this paragraph: Nonpolar-nonpolar interactions occur when two nonpolar liquids are mixed. An example of this is the interaction between toluene and octane (see Figures above and below ). The interactions between a molecule of toluene and a molecule of octane are relatively weak, but so are the toluene-toluene and octane-octane interactions. Because no strong intermolecular forces (like those between water molecules) need to be broken for mixing to occur, no strong interactions need to be formed in order for mixing to be a favorable process. Toluene and octane will form a homogeneous mixture. The phrase "like dissolves like" applies to these mixtures as well. In this case, nonpolar dissolves nonpolar. Q: What occurs when two nonpolar liquids are mixed? Choices: - sediment - nonpolar interactions - refracted - nonpolar interactions - polar-nonpolar interactions - nonpolar-nonpolar interactions A:

Ans:nonpolar-nonpolar interactions
Question: Answer the following question given this paragraph: An electroscope is a device used to study charge. When a positively charged object (the rod) nears the upper post, electrons flow to the top of the jar leaving the two gold leaves postivley charged. The leaves repel each other since both hold postive, like charges. The VSEPR theory says that electron pairs, also a set of like charges, will repel each other such that the shape of the molecule will adjust so that the valence electron-pairs stay as far apart from each other as possible. Q: What device is used to study charge? Choices: - microtome - nannostomus - microscope - electroscope A:
Answer:
electroscope
