Answer:

The answers are c)are the most reinforcing, generate the greatest immediate sensual appeal, and produce the most powerful psychological dependence.

Explanation:

Like all psychoactive substances, amphetamines affect the central nervous system and have stimulating effects (empathy, sensuality, confusion, etc.), producing an alert state along with various reactions in perception. Some individuals also report optical and auditory illusions. On many occasions this is also favored by the existence of intense visual and auditory stimuli, as happens for example at parties. However, most of these desired effects have tolerance with repeated doses of the same substances and even cross tolerance with doses of other substances. With the appearance of this tolerance other effects appear such as aggressiveness, anxiety symptoms, panic attacks, etc.

Among the medical complications related to the use of these substances, acute neurological complications, seizures and cerebrovascular diseases stand out.

seraphim [82]

Answer:

east to west

Explanation:

The stars and moon are the celestial bodies which are located at distant.

The distance of stars vary but moon and sun remain same. As our Earth rotates at its own axis, other celestial bdies seem to move.

As Earth spins from west to east, the stars and moon seems to move from east to west direction at night and same with Sun, it also seem to move from east to west.

Hence, the correct option is east to west.

Making changes to the secondary structure of hair has a different outcome than making changes to its tertiary or quaternary stru
DanielleElmas [232]

The outcome differs in the way that the protein folds itself at each level. The changes in the way that it folds lead to:

modifications in the function, shape or in the combination with other proteins.

Protein has different levels of structure. Each of them is related to how the amino acids and other molecules interact with each other. Hair is made of proteins, so if one of the structures is affected, the hair is too.

Let's analyse what happens in each level of structure:

  • In the case of the primary structure, which is the sequence of amino acids, the modification will give a non-functional protein that will not fold into the following structural level. So, there won't be new hair.
  • For the secondary structure, a modification here can lead to a different folding. In other words, it can change from an α helix to a β pleated sheet or the other way round. This will give a different shape to the hair, like curly or straight.
  • A modification in the tertiary structure modifies the interaction of the R groups in the protein, so the three-dimensional structure that this interaction gives will change, giving a different type of hair.
  • Lastly, if we modify the quaternary structure, the protein won't interact with some proteins, but it may interact with others.

In conclusion, the modification of the secondary structure changes the interaction between the elements of the protein giving hair with different shapes.
