Answer:

The base adenine pairs with thymine, and the base cytosine pairs with guanine.

Explanation:

From Chargaff's discovery, which was that the DNA of any given species contains equal amounts of adenine and thymine, and equal amounts of cytosine and guanine, we can deduce that if there is an equal amount of two bases in DNA, those two bases must pair together. From this information, we can then go on to say that since there are equal amounts of adenine and thymine, they pair together, and since there are equal amounts of cytosine and guanine, they also pair together.

Ms. Carroll went to her doctor's office with pain in her right shoulder blade and learned she was having a gallbladder attack. Y
BARSIC [14]

Answer:

Gallbladder Shoulder Pain

Explanation:

Inflammation of the gallbladder, liver and pancreas occurs when gallstones develop in our body . Pressure on different types of nerves is produce when these organs develop inflammation. One of this nerve, the right phrenic nerve can travel upward towards the shoulder and upper back. When you apply pressure to the right phrenic nerve, it produces pain in the right shoulder. This is the reason why many medical resources acknowledge that right shoulder pain is one of the primary symptoms of a gallbladder attack.

How can histograms help you describe a population? Use the word bank above to help you explain your answer.
krek1111 [17]

Answer: It shows the distribution of the population with respect to a characteristic, quantitative and continuous, such as the weight or height of a population. It is used to determine the degree of homogeneity of the values studied, or to see the degree of variability, and therefore, the dispersion of all the values taken by the parts.

Explanation:

A histogram is a graphical representation of a variable using bars. In such a bar, <u>its area is proportional to the frequency of the values represented</u>. Thus, it shows the distribution of the population, or of the sample, with respect to a characteristic, quantitative and continuous, such as the weight or height of a population. It is used to determine the degree of homogeneity of the values studied, or to see the degree of variability, and therefore, the dispersion of all the values taken by the parts.

In order to construct a histogram first we need to have a frequency table with all the information. On the abscissa axis (horizontal axis) the intervals are placed from smallest to largest.  On the ordinate axis (vertical axis), the absolute frequencies of each of the intervals are represented.  Then, the rectangular bars of equal width are drawn, and the height represents the absolute frequency. All bars touch the bars next to each other, unless an interval has zero frequency (the height of the bar will also be zero).

<u>Thus, histograms are used to describe populations since they represent a variable and in what proportion of the population it is found.</u>
