Answer the following question given this paragraph: Reproduction Reproduction in prokaryotes is asexual and usually takes place by binary fission. Recall that the DNA of a prokaryote exists as a single, circular chromosome. Prokaryotes do not undergo mitosis. Rather the chromosome is replicated and the two resulting copies separate from one another, due to the growth of the cell. The prokaryote, now enlarged, is pinched inward at its equator and the two resulting cells, which are clones, separate. Binary fission does not provide an opportunity for genetic recombination or genetic diversity, but prokaryotes can share genes by three other mechanisms. Q: Prokaryotes divide via binary fission and do not undergo what process of cell division? Choices: - prophase - meiosis - fusion - mitosis A:
mitosis

Answer the following question given this paragraph: Q: What can accept a wide range of carbohydrates for catabolism? Choices: - photosynthesis - cellular respiration - enzymes - glycolysis A:
(Answer)
glycolysis
Ques: Answer the following question given this paragraph: The stored food in a seed is called endosperm . It nourishes the embryo until it can start making food on its own. Q: What is the stored food in a seed called? Choices: - pollin - membrane - larval - endosperm A:
Ans: endosperm
(Q).
Answer the following question given this paragraph: Most of the elements we know about do not exist freely in nature. Sodium cannot be found by itself (unless we prepare it in the laboratory) because it interacts easily with other materials. On the other hand, the element helium does not interact with other elements to any extent. We can isolate helium from natural gas during the process of drilling for oil. Q: Sodium is an example of what sort of thing that cannot exist by itself in nature? Choices: - concept - compound - aspect - element A:
(A).
element
Ques:Answer the following question given this paragraph: Of course, a net external force is needed to cause any acceleration, just as Newton proposed in his second law of motion. So a net external force is needed to cause a centripetal acceleration. In Centripetal Force, we will consider the forces involved in circular motion. PhET Explorations: Ladybug Motion 2D Learn about position, velocity and acceleration vectors. Move the ladybug by setting the position, velocity or acceleration, and see how the vectors change. Choose linear, circular or elliptical motion, and record and playback the motion to analyze the behavior. Q: Of course, a net external force is needed to cause any acceleration, just as newton proposed in his second law of what? Choices: - land - gravity - speed - motion A:

Ans:motion
Ques:Answer the following question given this paragraph: It can be really exciting to explore a big underground cave like the one in this picture. Do you know how caves form? Believe it or not, water is the answer. Water slowly dissolves rocks, especially certain types of rocks such as limestone. How does something as mild and harmless as water cause hard rocks to dissolve? In this chapter, you'll find out. Q: Caves form over time when what causes rocks like limestone to dissolve? Choices: - weather - acid - air - water A:

Ans:
water
