Hypothesis:
PLEASE FILL IN THE BLANK ABOVE!!
The independent variable is the size of the coin. The number of water drops is the dependent variable. control is a coin with no water. the constant is the same dropper / same water.
The cause is the independent variable. Its value is unaffected by the other study variables. The effect is the dependent variable. Changes in the independent variable affect its value.
By presenting both variables in the statement below in a way that makes sense, you may quickly determine which variable in your experiment is the Independent Variable (IV) and which one is the Dependent Variable (DV). "The DV changes as a result of the IV. There is no chance that DV might alter IV in any way.

What is the smallest number of individuals that would still allow a population to be able to persist or grow, ensuring long-term survival?
The smallest number of individuals that would still allow a population to be able to persist or grow, ensuring long-term survival is referred to as a minimal viable population.
In the field of ecology, we can simply define minimal viable populations as the smallest number of viable populations of a species living in an area. The species reaching a minimal viable population still have the capability to grow itself and ensure survival in an area.
The minimal viable population of a species is important for an ecologist to make research. Through a minimal viable population, an ecologist can determine which factors of an ecosystem help a population in survival and which ones act as its disruption.

A current scientific theory would be revised based on the new findings if new technologies gave us information that challenged what scientists currently understand about natural selection.
A scientific theory results from research made by different scientists. These researches have a solid stance for proving a scientific theory. However, scientific theories are subject to being revised over time and can be changed accordingly if new research provides proper evidence for its modifications.
If through modern technologies, new information is proved then amendments or modifications are made to the previous theory rather than forming a completely new theory and discarding the previous one altogether.
After new information has been proved about natural selection, certain revision steps will occur and based on these revisions, the necessary modifications to the previous theory will be made.
Although a part of your question is missing, you might be referring to this question:

How many males are taller than 175 cm and approximately what persentage of the total is that? Which graphs illustrate the answer to previous question?
(a) Under which conditions would a dark brown mouse be most likely to escape predation at night?
Bar graphs are used to interpret results in an experiment by comparing the change of the dependent variable under different scenarios. D) on dark-colored soil with full moonlight.
How to interprete a bar graph?
A bar graph represents the relationship between two variables, the dependent and the independent one.
Usually,
Independent variable ⇒ X axisDependent variable ⇒ Y axis
Bars represent how the dependent variables react or respond to changes in the independent variable.
These charts are used to make comparisons. This means that by looking at the different bars, the researcher can to compare how the dependent variable responds under different scenarios of the independent variable. For instance, in which situation the bar is higher or shorter.
Bar graphs turn out to be an easy and reliable way to interpret results in an experiment.
Now let us analyze this example,
The researcher compares how many mice were caught by the owl under different scerarios: different substrate color, under moonlight or not, and according to their coat color.
Coat color: white and brownSubstrate: light and darkMoonlight: Full moon - No moon
The dependent variable is the number of caught mice, which depends on coat color, moonlight, and substrate color.
The independent variables are coat color, moonlight, and substrate color. Any change in them will affect the dependent variable.
Notice that even when the researcher can not manipulate the coat color, this is also an independent variable.
The question asks under which conditions would a dark brown mouse be most likely to escape predation at night?
Well, to answer it, we just need to compare the bars height.
Higher bars means a higher number of caught miceLower bars means that mice managed to scape predationSince the question ONLY asks about brown mice, we will limit out interpretation to brown bars.
The shortest brown bar reflects that on dark soil and under a full moon, the number of brown caught mice was the lowest, with only about 12 individuals eaten.The highest brown bar reflects that on light soil, and under no moon, the number of brown caught mice was the highest, with about 37 animals eaten.
The bar that expresses the conditions under which brown mice managed to scape predation is the shortest one, because it tells us about the lowest number of individuals caught by the owl.
So the answer to this question is on dark-colored soil with full moon light. Option D).

Explain the difference between vertical and horizontal integration. How were these business models representative of monopolies?
When two firms combine, whose products and production levels are the same, then this is known as Horizontal Integration. Vertical Integration is when a firm takes over another firm or firms, that are at different stages on the same production path.
Horizontal Integration is a kind of business expansion strategy, wherein the company acquires the same business line or at the same level of the value chain so as to eliminate competition to a greater extent. Conversely, Vertical Integration is used to rule over the entire industry by covering the supply chain. It implies the integration of various entities engaged in different stages of the distribution chain.
The greatest advantage of horizontal integration is that it eliminates competition between firms, which ultimately extends the market share of the company. Conversely, Vertical Integration results in lowering the cost of production and wastage.
Horizontal Integration helps to acquire control over the market, but Vertical Integration is a strategy used for gaining control over the whole industry.

It would it still be preferable to introduce the drug locally because It would make use of or take advantage of glucocorticoids' anti-inflammatory characteristics.
The effects on glucose metabolism that would occur if glucocorticoids were taken orally and circulated throughout the body are eliminated by local injections.
Although inflammation is a natural process that helps the body repair and protect itself from harm, it needs to be treated when it lasts for more than a few days or weeks. Inflammation in the joints is a symptom of arthritis.
An example of an anti-inflammatory medicine is corticosteroids. Treatment for rheumatologic conditions such lupus, vasculitis, and rheumatoid arthritis is widespread (inflammation of the veins). Explicit corticosteroids combine prednisone and cortisone.
Glucocorticoids (GCs) are frequently used to treat cancer, autoimmune conditions, and inflammation. For instance, cortisol boosts the production of glucose from non-carbohydrate sources like proteins, increasing the amount of glucose that is available for use as fuel.
When injected into the body at concentrations greater than those occurring naturally, glucocorticoids suppress some immunological components. Consequently, inflammatory disorders like arthritis are occasionally treated with glucocorticoids.
