Ques: Answer the following question given this paragraph: The nucleus of many cells also contains a central region called the nucleolus . The job of the nucleolus is to build ribosomes. These ribosomes flow out the nuclear pores into the cytoplasm. Ribosomes are organelles that make proteins in the cytoplasm. See the composition of the nucleus pictured below ( Figure below ). Q: The job of the nucleolus is to build what? Choices: - chromosomes - electrons - cells - ribosomes A:
Ans: ribosomes
(Q).
Answer the following question given this paragraph: Currents also flow deep below the surface of the ocean. Deep currents are caused by differences in density at the top and bottom. More dense water takes up less space than less dense water. It has the same mass but less volume. Water that is more dense sinks. Less dense water rises. What can make water more dense?. Q: What is caused by differences in density at the top and bottom of the ocean? Choices: - shallow currents - still water - flat currents - deep currents A:
(A).
deep currents
Ques:Answer the following question given this paragraph: Why is activation energy needed? A reaction won't occur unless atoms or molecules of reactants come together. This happens only if the particles are moving, and movement takes energy. Often, reactants have to overcome forces that push them apart. This takes energy as well. Still more energy is needed to start breaking bonds in reactants. The graphs in Figure below show the changes in energy in endothermic and exothermic reactions. Both reactions need the same amount of activation energy in order to begin. Q: What is required to break bonds in reactants? Choices: - food - gas - protein - energy A:

Ans:energy
