Answer:

Drought in the Sahel in the 1970s and 1980s made it look like the desert was expanding, because the reduction of rainfall at the desert margin (the Sahel) caused a reduction in vegetation. Warm, moist air rises near the equator, then cools and condenses its moisture, which falls as rain or snow

According to the central principle of utility, actions are right in proportion, as they tend to promote happiness, and wrong, as they tend to produce the reverse of happiness (pain).

<h3>What is the principle of utility?</h3>

The concept of the principle of utility refers to the standard that determines whether or not any action is acceptable. According to the propensity it shows to either increase or decrease the happiness of the party whose interest is under consideration, or, to put it another way, to support or oppose that happiness.

For instance, the utilitarian viewpoint holds that you should select the flavour of ice cream that will make you feel the happiest if you are making a decision for yourself. If you like chocolate but detest vanilla, go with chocolate for the delight it will provide, and stay away from vanilla because it will make you unhappy.

Explanation:

Hello! The theory suggests that emotions occur as a result of physiological reactions to events. In addition, this emotional reaction is dependent on the way we interpret those physical reactions. This means that for example we do not cry because we are sad, we are sad because we cry.

Several students have been practicing drawing their models of nucleotides. Whose model do you think is most consistent with the
RSB [31]

The first description of the DNA (deoxyribonucleic acid)chain was done by Watson and Crick in 1953, the nucleotides that constitute the DNA are four: cytosine (C), guanine (G), timine (T) and adenine (A). When doing a model is essential to remember that cytosine ONLY joins guanine and timine only link adenine, this is due to the size and chemical properties of each molecule. Later, another related and similar and molecule was discovered, the ribonucleic acid or RNA, which also is constructed by nucleotides.

In both cases, the nucleotides are compound of 3 main components: a nitrogen base, a pentose and a phosphate. When the molecule lacks the phosphate group, is called nucleoside. Depending on the chain ( DNA or RNA) the nitrogen base derives from purine (adenine and guanine) or pyrimidine (cytosine or timine) just in the RNA instead of timine is uracil (U)

The union is established between adjacent molecules through the phosphate, while among each other through the nitrogen base-remember C=G and T or U=A. The core of each molecule is the pentose. Therefore the best representation of the molecule is attached

What does marcellinus mean when he describes the Huns as being glued to their horses
qwelly [4]
They're glued to their horses because they're nomadic, so they never completely settle in one place.  I have never read Marcellinus before but that seems like the most logical answer. Hope thus helps!
