Q: Thylakoids in a chloroplast contain what plant pigment? Read this paragraph and choose the correct option from the provided answers: 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. Choices: - melanin - dye - ultramarine - chlorophyll A:
chlorophyll

Q: What does increased temperature cause the volume to do in a gas? Read this paragraph and choose the correct option from the provided answers: Equal volumes of four different gases at the same temperature and pressure contain the same number of gaseous particles. Because the molar mass of each gas is different, the mass of each gas sample is different even though all contain 1 mol of gas. The relationships among the volume of a gas and its pressure, temperature, and amount are summarized in Figure 10.10 "The Empirically Determined Relationships among Pressure, Volume, Temperature, and Amount of a Gas". Volume increases with increasing temperature or amount but decreases with increasing pressure. Choices: - disappear - decrease - halve - increase A:
increase
