Why did a well-known pharmacologist refer to the recreational use of cocaine, crack cocaine, amphetamine, and methamphetamine as
Dimas [21]

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.

Blue whales have 44 chromosomes in every cell. determine how many chromosomes you would expect to find in the following:Sperm ce
baherus [9]

Sperm cell: We expect to find 22 chromosomes.

The spermatozoon is a small cell (5 micrometers in diameter), much smaller than the ovum, but with a movable tail (a flagellum) 60 micrometers long. To be lightweight and mobile, to quickly reach the egg, the sperm gains space by minimizing its cytoplasm and compacting its DNA. Head is covered with the acrosome, a pocket full of enzymes that will be used to pierce the membrane of the egg.

It is a haploid cell because it contains half of the genetic material of the individual, lost at the time of meiosis during the process of spermatogenesis that the primordial germ cells undergo in the seminiferous tubules of the testes.


Egg Cell: We expect to find 22 chromosomes.

The egg is the sexual cell (or gamete) produced by the females of the animals.

Like all gametes, the egg is haploid, it contains half of the chromosomes of the future embryo, so the number of chromosomes will be 22 instead of 44. Then this egg will meet a sperm cell to gather their chromosome and form an embryo of 44 chromosomes.


Daughter Cell from Mitosis: We expect to find 44 chromosomes.

Mitosis, which ensures the birth of cells identical to the mother cell during asexual multiplication (so the number of chromosomes will remain the same, it will not divide in two).

Mitosis is an asexual cell division. This means that it is just a division of a mother cell into two daughter cells, which will inherit exactly the same genetic inheritance.


Daughter Cell from Meiosis II: We expect to find 22 chromosomes.

Meiosis is a particular mode of division of the living cell by which an initial cell with 2n chromosomes (in this case 2n = 44 chromosomes), a diploid stage, gives rise to four daughter cells possessing only n chromosomes, a haploid stage (n = 22 chromosomes). Meiosis is one of the forms of cell reproduction, this process is performed on the gonads to produce gametes.
