How can etymologies help you know the meanings of scientific terms ?

When you understand the etymologies of scientific terms, they make a lot of sense in relation to the term. The etymologies themselves often serve as a reasonably okay definition for the term. 

Here's an example, many scientific terms have Greek or Latin etymologies. Take "archaeology" (for an example) Etymologically, it consists of two Greek words "archaeo" (old, ancient) and "logos" (a word, discourse, or study). Therefore, etymologically "archaeology" means "the study of old/ancient things."

Answer:

Etymology regularly expresses the origin of a word and the origin of its root or ending, with which a medium idea of the meaning of the word can be given even though it is not known.

Explanation:

The etymology of a word will allow you by means of the meaning and origin of its parts (either the root or the ending) to identify the meaning of the word, for example, perhaps you have heard the word <u>hepatitis</u>, and perhaps you do not know what it means, It turns out that the first part <u>"hepa" comes from a Latin word that refers to the liver</u>, while the second part <u>"itis" comes from a Latin word that refers to all kinds of inflammation</u>, so you could deduce that the<u> Hepatitis is a type of inflammation of the liver</u>, which would give you a general idea of the disease.

Five students performed a Kjeldahl nitrogen analysis of a protein sample. The following weight % nitrogen values were determined
Sunny_sXe [5.5K]

Answer:

G_calculated = 1.756

The outlier should be rejected, as G_cal > G_tab (= 1.463) at 95 % confidence.

Explanation:

The Grubb's test is used for identifying an outlier in data, which is from the same population. For this, a statistical term, G, is calculated for the suspected outlier. If the calculated value is greater than the tabulated G value then the suspected value is rejected. This term is given as,

G_calculated = | suspect value - mean| / s

Here,  suspect value is 13.8, mean is to be taken of all the data (including suspected value). s is the standard deviation of the sample data.

s is calculated from the following formula:

s = (Σ(xi - x)²/(N-1))^1/2

Here, x is the mean, which is 15.24, xi is individual value and N is the total number of data (5).

From the above formula, s is found to be

Standard Deviation, s = 0.820

Now for G value,

G_calculated = | 13.8 - 15.24| / (0.820)

G_ calculated = 1.756

The tabulated G value at 95 % confidence and N -1 (5 - 1 = 4) degree of freedom is, 1.463.

As calculated G (1.756) is greater than the tabulated G (1.463), the value 13.8 is considered an outlier at 95 % confidence.

What must happen to uranium before it can be used as a fuel source?
Otrada [13]

Answer:

Uranium must be purified before it is used as a fuel source

Explanation:

The purer the uranium sample, the more the concentration of uranium in the fuel is.

Whenever uranium is extracted from nature, it contains a lot of impurities. Only a few special nuclear reactors can utilize uranium in this raw state. most of the others have to get uranium to become about 3% pure before they begin using it.

To do this, uranium has to be passed through a series of chemical reactions all with the aim of extracting the other compounds that may be present in the fuel.
