Answer:
nitrates; cone of depression; confined; water table; unconfined; drainage field; spring.
Explanation:
Nitrogen-fixing bacteria in soil can convert excess nitrogen into nitrates, which can contaminate groundwater.
A cone of depression forms around a well when the water table begins to slope toward the well.
The water in an artesian well comes from a confined aquifer.
A well not only has to reach the water table but also has to go deeper.
Unconfined aquifers are more prone to pollution.
The two primary components of a septic system are a septic tank and a drainage field.
Groundwater that comes to the surface naturally is spring.

In nature, mutation rates are usually ______ to maintain alleles that are not favored in a population by natural selection.
In nature, mutation rates aren't usually high enough to maintain alleles that are not favored in a population by natural selection.
While in the wild, many populations are led by natural selection. This means that favorable traits are passed down through generations, while unfavorable traits are not. Traits that are best suited for the environment of the organism will prevail to help the chance of survival.
Mutation rates usually aren't high enough to create traits that are unfavorable to an organism. While mutations are still possible, it is still unlikely. The traits that are chosen by natural selection are most likely to be passed onto organisms and their offspring.

Answer:
Mitotic inhibitors are used in cancer treatment, because cancer cells are able to grow and eventually spread through the body (metastasize) through continuous mitotic division. Thus, cancer cells are more sensitive to inhibition of mitosis than normal cells.
Which resource does NOT need to be cycled by ecosystems because a continuous, unlimited supply is available?
Answer:
Solar energy
Explanation:
Solar energy is the resource that doesn’t need to be cycled by ecosystems because a continuous, unlimited supply is available.
The Sun provides the solar energy which is very important in plant’s food production and it isn’t dependent on the ecosystem and seasons. This is because the Sun provides light during the day and we experience daytime all year round. This is why the solar energy has a continuous, unlimited supply.
Data Collection: Pinky’s science fair project in junior high focused on an observation that the crickets outside her window chirped less frequently when the temperature was colder. Fun Fact: There are free “cricket chirp calculators” online you can explore, which didn’t exist freely online when Pinky was in junior high. Consider if data was collected consisting of the average number of cricket chirps at different temperatures in her backyard. 10. Which variable would be an independent variable?
Answer:
Different temperatures in her backyard
Explanation:
The independent variable would be the different temperatures in Pinky's backyard.
The independent variable is a variable whose value is not affected by another variable during research. It is a variable that directly affects the actual variable that is measured - the dependent variable. The independent variable is usually varied in order to see the kind of effect it will produce on the dependent variable.
In the case of Pinky, the different temperature at the backyard affects the number of cricket chirps. Hence, the temperature is considered the independent variable while the number of cricket chirp is considered the dependent variable.

You would expect high levels of blood glucose and the presence of glucose and ketones in Mr. Gutteman's urine if:
Answer:
The correct answer would be : Mr. Gutteman's pancreas is secreting too little insulin.
Explanation:
Insulin is a hormone produce by pancreas that maintain glucose level by using glucose for energy or to store for future use. Insulin prevent blood sugar level to go too high or too low.
Less production of this hormone cause high glucose level in blood that leads to glucose, ketone bodies in urine of a person.
Thus, the correct answer is : Mr. Gutteman's pancreas is secreting too little insulin.
Imagine that you wish to compare two different diets that will be fed to tadpoles raised in a lab. One diet is a meat-based fish food, and the other is the traditional diet of boiled lettuce. You want to see if the meat-based diet will be associated with an increase in the average weight of the tadpoles. In your experiment you keep all other factors, such as tadpole density per pan, temperature, pH, and the amount of food the same. The only difference between your control and experimental groups is the type of food the tadpoles receive. What is the independent variable for the tadpole diet experiment?
Answer:
TYPE OF DIET
Explanation:
Independent variable of an experiment is that variable that is subject to manipulation or changing by the experimenter in order to effect a response in the dependent variable.
According to the experiment in this question, the type of diet is changed for different groups of tadpoles in order to see the effect on their average weight. Based on this, the independent/manipulated variable is the TYPE OF DIET administered to each group of tadpole while the growth (average weight) of the tadpoles is the dependent variable.

What is a stimulus? What is homeostasis? How are irritability and homeostasis related? Describe an example of homeostasis, response and adaptation in a living organism.
Answer:
All is in order.......
stimulus is a thing or event that evokes a specific functional reaction in an organ or tissue.
homeostasis is the tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes.
Irritability is that characteristic of living organisms in being aware of, and being able to respond to, a stimulus which tends to disturb the steady state or homeostasis which all organisms prefer for maintaining life.
Humans' internal body temperature is a great example of homeostasis. When someone is healthy, their body maintains a temperature close to 98.6 degrees Fahrenheit (37 degrees Celsius). Being warm-blooded creatures, humans can increase or decrease temperature internally to keep it at a desirable level.

If two events are correlated, what must be true? (1 point)
O Both events have the same result.
O Both events have the same cause.
O The events tend to happen together.
O One event caused the other.
Answer:
Both events have the same cause.
Explanation:
Correlation in statistics refers to the measure of the relationship between two variables. Simply put, two variables are said to be correlated if a mutual relationship exists between them. This means that if two events correlates, a relationship in which, both events have the same cause, exists between them.
Correlation can be positive or negative depending on whether the increase of one event causes the other to increase (positive) i.e. they both move in a similar direction or the increase of one event causes the declination of the other (negative) i.e. they move in opposite directions.

The specific molecular changes that occur when a drug binds to a particular target site or receptor are referred to as
Answer:
Drug action.
Explanation:
Drug action can be defined, in short, as the action of the drug on the body. The effects of almost all drugs are a consequence of their interaction with macrocellular components of the body. These interactions modify the function of the relevant component and thereby initiate the biochemical and physiological changes that characterize the response or reaction to the drug. Receptors are cellular structures that have a specific purpose and that are activated in their action by different substances.
