Answer the following question given this paragraph: After each mass extinction, new species evolve to fill the habitats where old species lived. This is well documented in the fossil record. Q: The fossil record shows that this type of event is followed by the evolution of new species to fill the habitats where old species lived? Choices: - minor extinction - moderate extinction - formation extinction - mass extinction A:
(Answer)
mass extinction
Ques: Answer the following question given this paragraph: Partly movable joints allow only very limited movement. Bones at these joints are held in place by cartilage. The ribs and sternum are connected by partly movable joints. Q: What are the bones in partly movable joints held in place by? Choices: - socket - tendons - collagen - cartilage A:
Ans: cartilage
(Q).
Answer the following question given this paragraph: groups of angiosperms: the monocots and the eudicots. Seed food reserves are stored outside the embryo, in the form of complex carbohydrates, lipids or proteins. The cotyledons serve as conduits to transmit the broken-down food reserves from their storage site inside the seed to the developing embryo. The seed consists of a toughened layer of integuments forming the coat, the endosperm with food reserves, and at the center, the well-protected embryo. Most flowers are monoecious or bisexual, which means that they carry both stamens and carpels; only a few species selfpollinate. Monoecious flowers are also known as "perfect" flowers because they contain both types of sex organs (Figure 26.14). Both anatomical and environmental barriers promote cross-pollination mediated by a physical agent (wind or water), or an animal, such as an insect or bird. Cross-pollination increases genetic diversity in a species. Q: Monoecious flowers are also known as "perfect" flowers because they contain both types of what organ? Choices: - vascular organ - respiratory organ - phloem - sex organ A:
(A).
sex organ
Ques:Answer the following question given this paragraph: What happens if a substance needs assistance to move across or through the plasma membrane? Facilitated diffusion is the diffusion of solutes through transport proteins in the plasma membrane. Facilitated diffusion is a type of passive transport. Even though facilitated diffusion involves transport proteins, it is still passive transport because the solute is moving down the concentration gradient. Q: What do you call the diffusion of solutes through transport proteins in the plasma membrane? Choices: - necessitated diffusion - exposed diffusion - Osmosis - facilitated diffusion A:

Ans:facilitated diffusion
Answer the following question given this paragraph: These values suggest that water should be oxidized at the anode because a smaller potential would be neededusing reaction (ii) for the oxidation would give a less-negative cell potential. When the experiment is run, it turns out chlorine, not oxygen, is produced at the anode. The unexpected process is so common in electrochemistry that it has been given the name overpotential. The overpotential is the difference between the theoretical cell voltage and the actual voltage that is necessary to cause electrolysis. It turns out that the overpotential for oxygen is rather high and effectively makes the reduction potential more positive. As a result, under normal conditions, chlorine gas is what actually forms at the anode. Now consider the cathode. Three reductions could occur:. Q: What are the two metals within a battery called? Choices: - sheath and a cathode - anode and sheath - anode and diode - anode and a cathode A:
anode and a cathode
