Q: Answer the following question given this paragraph: Both mitosis and meiosis result in eukaryotic cells dividing. So what is the difference between mitosis and meiosis? The primary difference is the differing goals of each process. The goal of mitosis is to produce two daughter cells that are genetically identical to the parent cell, meaning the new cells have exactly the same DNA as the parent cell. Mitosis happens when you want to grow, for example. You want all your new cells to have the same DNA as the previous cells. The goal of meiosis, however, is to produce sperm or eggs, also known as gametes . The resulting gametes are not genetically identical to the parent cell. Gametes are haploid cells, with only half the DNA present in the diploid parent cell. This is necessary so that when a sperm and an egg combine at fertilization , the resulting zygote has the correct amount of DNAnot twice as much as the parents. The zygote then begins to divide through mitosis. Q: Both mitosis and meiosis result in eukaryotic cells doing what? Choices: - multiplication - friction - limiting - dividing A:
A: dividing

Q: Answer the following question given this paragraph: Minerals can form various shapes. Polygons are pictured below ( Figure below ). The shapes form as the minerals are broken along their cleavage planes. Cleavage planes determine how the crystals can be cut to make smooth surfaces. People who cut gemstones follow cleavage planes. Diamonds and emeralds can be cut to make beautiful gemstones. Q: The shapes of minerals form as they are broken along what planes? Choices: - parallel planes - sedimentary planes - calcium planes - cleavage planes A:
A: cleavage planes

Q: Answer the following question given this paragraph: Competition within a species is called intraspecific competition. It leads to natural selection within the species, so the species becomes better adapted to its environment. Q: Competition within a species is called what? Choices: - reproducible competition - species competion - internal competition - intraspecific competition A:
A: intraspecific competition

Q: Answer the following question given this paragraph: All weather takes place in the atmosphere. Nearly all of it in the lower atmosphere. Weather refers to the conditions of the atmosphere at a given time and place. Climate is the average of weather over a long time. Q: Nearly all weather occurs in the lower part of what? Choices: - the mesosphere - the ionosphere - the lithosphere - the atmosphere A:
A: the atmosphere
