Answer the following question given this paragraph: All living things need water. For most human uses, water must be fresh. Of all the water on Earth, only 1 percent is fresh, liquid water. Most of the rest of Earth's water is either salt water in the ocean or ice in glaciers and ice caps. Q: Although humans require it, what accounts for just one percent of all water on earth? Choices: - snow - salt water - glaciers - fresh water A:
fresh water

Answer the following question given this paragraph: A: Breathing consists of inhaling and exhaling, and its purpose is to move gases into and out of the body. Oxygen needed for cellular respiration is brought into the body with each inhalation. Carbon dioxide and water vapor produced by cellular respiration are released from the body with each exhalation. Q: How is carbon dioxide and water vapor that is produced by cellular respiration released? Choices: - peroxidation - fermentation - evaporation - exhalation A:
(Answer)
exhalation
Ques: Answer the following question given this paragraph: Fruit is the preferred food for almost all primates except humans. However, most primate species are omnivorous and consume a variety of plant and animal foods. For example, they may eat leaves, seeds, bird eggs, insects, and other small animals. Chimpanzees may band together and hunt for animals to kill and eat. They may even sharpen sticks and use them as spears when they hunt.

Q: What is the preferred food for almost all primates except for humans? Choices: - grass - wheat - corn - fruit A:
Ans: fruit

Ques:Answer the following question given this paragraph: The Chromosome 18 Inversion Not all structural rearrangements of chromosomes produce nonviable, impaired, or infertile individuals. In rare instances, such a change can result in the evolution of a new species. In fact, a pericentric inversion in chromosome 18 appears to have contributed to the evolution of humans. This inversion is not present in our closest genetic relatives, the chimpanzees. Humans and chimpanzees differ cytogenetically by pericentric inversions on several chromosomes and by the fusion of two separate chromosomes in chimpanzees that correspond to chromosome two in humans. The pericentric chromosome 18 inversion is believed to have occurred in early humans following their divergence from a common ancestor with chimpanzees approximately five million years ago. Researchers characterizing this inversion have suggested that approximately 19,000 nucleotide bases were duplicated on 18p, and the duplicated region inverted and reinserted on chromosome 18 of an ancestral human. A comparison of human and chimpanzee genes in the region of this inversion indicates that two genesROCK1 and USP14that are adjacent on chimpanzee chromosome 17 (which corresponds to human chromosome 18) are more distantly positioned on human chromosome 18. This suggests that one of the inversion breakpoints occurred between these two genes. Interestingly, humans and chimpanzees express USP14 at distinct levels in specific cell types, including cortical cells and fibroblasts. Perhaps the chromosome 18 inversion in an ancestral human repositioned specific genes and reset their expression levels in a useful way. Because both ROCK1 and USP14 encode cellular enzymes, a change in their expression could alter cellular function. It is not known how this inversion contributed to hominid evolution, [1] but it appears to be a significant factor in the divergence of humans from other primates. Translocations A translocation occurs when a segment of a chromosome dissociates and reattaches to a different, nonhomologous chromosome.... Q: Not all structural rearrangements of chromosomes produce nonviable, impaired, or infertile individuals. in rare instances, such a change can result in the evolution of what? Choices: - new order - new mutation - new family - new species A:

Ans:new species
Ques:Answer the following question given this paragraph: Surface currents are like streams flowing through the surface of the ocean. They are caused mainly by winds. Earth's rotation influences their direction. This is called the Coriolis effect. Surface currents may affect the climate of nearby coasts. Q: What are surface currents mainly caused by? Choices: - lightning - waves - rains - winds A:

Ans:
winds
