Answer the following question given this paragraph: With logistic growth, the population starts out growing slowly, and then the rate of growth increasesbut only to a point. The rate of growth tapers off as the population size approaches its carrying capacity. Carrying capacity is the largest population size that can be supported in an area without harming the environment. This type of growth characterizes many populations. Q: With logistic growth, how does population growth start out? Choices: - exponentially - rapidly - steadily - slowly A:
slowly
Answer the following question given this paragraph: Air temperature changes with altitude. This does not occur in the same way as pressure and density, which decrease with altitude. Changes in air temperature are not regular. A change in temperature with distance is called a temperature gradient . Q: A change in temperature with distance is called a what? Choices: - oxygen gradient - speed gradient - solution gradient - temperature gradient A:
temperature gradient
Q: Answer the following question given this paragraph: Coelacanths are ancient fish with just two living species. They are at risk of extinction because of their very small numbers. Q: Which ancient fish has just two living species and is at risk of extinction? Choices: - latimeria - hominids - squids - coelacanths A:
A: coelacanths
Question: Answer the following question given this paragraph: Brewers of beer and wine use yeast to add alcohol to beverages. Traditional varieties of yeast not only make but also limit the quantity of alcohol in these beverages, because above 18% by volume, alcohol becomes toxic to the yeast itself. Wine is produced by fermentation of the natural sugars present in grapes and other kinds of fruit. Beer, whiskey, and vodka are produced by fermentation of grain starches that have been converted to sugar by the enzyme amylase, and rum is produced by fermentation of sugarcane. In each of these fermentations, sugars are converted into small amounts of ATP, using and regenerating NAD + in the process, and producing ethanol and carbon dioxide. Scientists have recently developed new strains of yeast which can tolerate up to 25% alcohol by volume. These are used primarily in the production of ethanol fuel. Q: Why do beer brewers add yeast to the wort? Choices: - reduce alcohol - add carbonation - increase longevity - to make alcohol A:
Answer: to make alcohol

Answer the following question given this paragraph: 19.4 Community Ecology Communities include all the different species living in a given area. The variety of these species is referred to as biodiversity. Many organisms have developed defenses against predation and herbivory, including mechanical defenses, warning coloration, and mimicry. Two species cannot exist indefinitely in the same habitat competing directly for the same resources. Species may form symbiotic relationships such as commensalism, mutualism, or parasitism. Community. Q: Commensalism, mutualism, and parasitism are known as what type of relationships? Choices: - simple - peculiar - various - symbiotic A:
**Answer**
symbiotic

Answer the following question given this paragraph: Covalent bonds are responsible for many of the properties of covalent compounds. Covalent compounds have relatively low boiling points, cannot conduct electricity, and may not dissolve in water. Q: What is responsible for many properties of covalent compounds, which have relatively low boiling points, cannot conduct electricity, and may not dissolve in water? Choices: - ionic charge - accretion bonds - atomic weight - covalent bonds A:
(A).
covalent bonds
