Answer the following question given this paragraph: In warmer regions, plants and bacteria grow faster. Plants and animals weather material and produce soils. In tropical regions, where temperature and precipitation are consistently high, thick soils form. Arid regions have thin soils. Q: What happens to growth of plants and bacteria in warmer regions? A:
OPTIONS:
- they mutate
- they are stunted
- they grow slower
- they grow faster

Answer: they grow faster

Question: Answer the following question given this paragraph: The Chesapeake Bay (Figure 20.15a) is one of the most scenic areas on Earth; it is now in distress and is recognized as a case study of a declining ecosystem. In the 1970s, the Chesapeake Bay was one of the first aquatic ecosystems to have identified dead zones, which continue to kill many fish and bottomdwelling species such as clams, oysters, and worms. Several species have declined in the Chesapeake Bay because surface water runoff contains excess nutrients from artificial fertilizer use on land. The source of the fertilizers (with high nitrogen and phosphate content) is not limited to agricultural practices. There are many nearby urban areas and more than 150 rivers and streams empty into the bay that are carrying fertilizer runoff from lawns and gardens. Thus, the decline of the Chesapeake Bay is a complex issue and requires the cooperation of industry, agriculture, and individual homeowners. Of particular interest to conservationists is the oyster population (Figure 20.15b); it is estimated that more than 200,000 acres of oyster reefs existed in the bay in the 1700s, but that number has now declined to only 36,000 acres. Oyster harvesting was once a major industry for Chesapeake Bay, but it declined 88 percent between 1982 and 2007. This decline was caused not only by fertilizer runoff and dead zones, but also because of overharvesting. Oysters require a certain minimum population density because they must be in close proximity to reproduce. Human activity has altered the oyster population and locations, thus greatly disrupting the ecosystem. The restoration of the oyster population in the Chesapeake Bay has been ongoing for several years with mixed success. Not only do many people find oysters good to eat, but the oysters also clean up the bay. They are filter feeders, and as they eat, they clean the water around them. Filter feeders eat by pumping a continuous stream of water over finely divided appendages (gills in the case of oysters) and capturing prokaryotes, plankton, and fine organic particles... Q: Oysters require a certain minimum population density because they must be in close proximity to do this? A:
OPTIONS:
- multiply
- replicate
- feed
- reproduce
Answer: reproduce

Q: Answer the following question given this paragraph: Figure 9.3 This car is in dynamic equilibrium because it is moving at constant velocity. There are horizontal and vertical forces, but the net external force in any direction is zero. The applied force F app between the tires and the road is balanced by air friction, and the weight of the car is supported by the normal forces, here shown to be equal for all four tires. Q: When is a moving car said to be in dynamic equilibrium? A:

OPTIONS:
- at rest
- at homeostasis
- when accelerating
- zero net force

A: zero net force

input: OPTIONS:
- biological utility
- biological engineering
- genetic employing
- genetic engineering Now, answer this question: Answer the following question given this paragraph: Treating genetic disorders is one use of biotechnology. Biotechnology is the use of technology to change the genetic makeup of living things for human purposes. It's also called genetic engineering. Besides treating genetic disorders, biotechnology is used to change organisms so they are more useful to people. Q: What is the use of technology to change the genetic makeup of living things for human purposes? A:
A:
output: genetic engineering

Question: Answer the following question given this paragraph: Protostomes and Deuterostomes Bilaterally symmetrical, triploblastic eucoelomates can be divided into two groups based on differences in their early embryonic development. Protostomes include phyla such as arthropods, mollusks, and annelids. Deuterostomes include. Q: What are the two groups that tripoblastic eucoelomates can be divided into based on early embryonic development differences? A:
OPTIONS:
- protostomes and eurostomes
- heterodimers and deuterostomes
- odontoblasts and deuterostomes
- protostomes and deuterostomes
Answer:
protostomes and deuterostomes
