Q: In eukaryotes, the major mechanism for shuffling genes is what? Read this paragraph and choose the correct option from the provided answers: 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. Choices: - suggesting reproduction - subject reproduction - asexual reproduction - sexual reproduction A:
sexual reproduction

Q: What is the basis of the classification of protists? Read this paragraph and choose the correct option from the provided answers: Protists are classified based on traits they share with other eukaryotes. There are animal-like, plant-like, and fungus-like protists. The three groups differ mainly in how they get carbon and energy. Choices: - conditions shared - mutations shared - tails shared - traits shared A:
traits shared

Q: Along with other elements, most ores are made of what? Read this paragraph and choose the correct option from the provided answers: When the ore leaves the mine, it is not yet a useful material ( Figure below ). Most ores are a combination of metal and other elements. The rocks are full of valuable minerals. They also contain rock that isn't valuable, which is called waste rock. The valuable minerals must be separated from the waste rock. Choices: - coal - crystals - sodium - metal A:
metal

Q: Lipids are organic compounds that consist of carbon, hydrogen, and? Read this paragraph and choose the correct option from the provided answers: Lipids are organic compounds that consist of carbon, hydrogen, and oxygen. They are made up of fatty acids and other compounds. They provide cells with energy, store energy, and help form cell membranes. Choices: - nitrogen - methane - helium - oxygen A:
oxygen
