Answer the following question given this paragraph: Sexual reproduction In eukaryotes, the major mechanism for shuffling genes is sexual reproduction. Because sex (usually) requires that organisms cooperate sex represents an example of social evolution. So what are the benefits of sexual reproduction? 342 Sexual reproduction involves the alternation of diploid (two copies of each chromosome) and haploid (one copy of each chromosome) cell types. In a diploid cell, the two copies of a particular gene can be different, the the organisms is said to be heterozygous for that gene. Different alleles can (but do not necessarily do) encode functionally distinct gene products and can be associated with different phenotypes (discussed in greater detail in the future two-semester version). We can then characterize different alleles with respect to one one another. Assume that allele-1 is associated with phenotype-1 342. Q: In eukaryotes, the major mechanism for shuffling genes is what? Choices: - suggesting reproduction - subject reproduction - asexual reproduction - sexual reproduction A:
sexual reproduction

Answer the following question given this paragraph: Nonvascular plants include mosses, liverworts, and hornworts. They are the only plants with a life cycle in which the gametophyte generation is dominant. Figure below shows the life cycle of moss. The familiar, green, photosynthetic moss plants are gametophytes . The sporophyte generation is very small and dependent on the gametophyte plant. Q: What are the only plants with a life cycle in which the gametophyte generation is dominant? Choices: - vascular plants - nonpermeable - photoreactive - nonvascular A:
(Answer)
nonvascular
Ques: Answer the following question given this paragraph: Clouds form when air in the atmosphere reaches the dew point. Clouds may form anywhere in the troposphere. Clouds that form on the ground are called fog . Q: What are clouds that form on the ground called? Choices: - haze - smoke - canopy - fog A:
Ans: fog

Answer the following question given this paragraph: Long-term or high-dose exposure to radiation can harm both living and nonliving things. Radiation knocks electrons out of atoms and changes them to ions. It also breaks bonds in DNA and other compounds in living things. One source of radiation that is especially dangerous to people is radon. Radon is a radioactive gas that forms in rocks underground. It can seep into basements and get trapped inside buildings. Then it may build up and become harmful to people who breathe it. Long-term exposure to radon can cause lung cancer. Q: This knocks electrons from atoms and turns them into ions? Choices: - convection - chemical reactions - evaporation - radiation A:
(A).
radiation
Ques:Answer the following question given this paragraph: The molarity is 0.0129 M, the molality is 0.0129 m, the mole fraction is 2.33 10 , and the solution contains 1830 ppm Na2HPO4. Mole fraction is most useful for calculating vapor pressure, because Raoult's law states that the vapor pressure of a solution containing a non-volatile solute is equal to the mole fraction of solvent times the vapor pressure of the pure solvent. The mole fraction of the solvent is just one minus the mole fraction of solute. Q: The mole fraction of the solvent is just one minus the mole fraction of what? Choices: - nutrients - solution - molecules - solute A:

Ans:solute
Answer the following question given this paragraph: At each level of a food chain, a lot of energy is lost. Only about ten percent of the energy passes to the next level. Where does that energy go? Some energy is given off as heat. Some energy goes into animal wastes. Energy also goes into growing things that another consumer can't eat, like fur. It's because so much energy is lost that most food chains have just a few levels. There's not enough energy left for higher levels. Q: Loss of energy is the reason that what typically has few levels? Choices: - humans - the atmosphere - video games - food chain A:
food chain
