Answer the following question given this paragraph: Green light has a higher frequency than microwaves. It is possible to calculate it, but since the speed of an electromagnetic wave is constant we know that waves with higher wavelengths must have a lower frequency based on the wave equation. Q: What of a electromagnetic wave can be calculated using the wave equation due to their speed always being constant? Choices: - oscillation - resonance - sound - frequency A:
frequency

Answer the following question given this paragraph: Arthropods are invertebrates in Phylum Arthropoda. There are more than a million known species of arthropods. However, scientists estimate that only about a tenth of all arthropod species have been identified. In addition to insects, arthropods include animals such as spiders, centipedes, and lobsters. You can see why arthropods were successful both in the water and on land, by watching these excellent videos:. Q: In addition to insects, what large invertebrate phylum includes animals such as spiders, centipedes, and lobsters? Choices: - onychophora - fungi - ostracods - arthropoda A:
arthropoda

Answer the following question given this paragraph: A supervolcano eruption took place at Lake Toba in northern Sumatra about 75,000 years ago ( Figure below ). This was the largest eruption in the past 25 million years. As much as 2,800 cubic kilometers of material was ejected into the atmosphere. The result was a 6- to 10-year volcanic winter. Some scientists think that only 10,000 humans survived worldwide. The numbers of other mammals also plummeted. Q: A supervolcano that may have killed all but 10,000 humans resulted in what phenomenon, lasting up to a decade? Choices: - volcano fall - volcanic summer - volcano spring - volcanic winter A:
volcanic winter

Answer the following question given this paragraph: Transgenic Animals Although several recombinant proteins used in medicine are successfully produced in bacteria, some proteins require a eukaryotic animal host for proper processing. For this reason, the desired genes are cloned and expressed in animals, such as sheep, goats, chickens, and mice. Animals that have been modified to express recombinant DNA are called transgenic animals. Several human proteins are expressed in the milk of transgenic sheep and goats, and some are expressed in the eggs of chickens. Mice have been used extensively for expressing and studying the effects of recombinant genes and mutations. Q: Animals that have been modified to express recombinant dna are called what? Choices: - reproducing animals - mammalian animals - aquatic animals - transgenic animals A:
transgenic animals
