Darwin realized that the often exquisite fit of species to their environment is primarily the result of
bagirrra123 [75]
Natural Selection.
An easy and important way to remember this is by thinking of a species - let’s say a bright white moth. For ages, these moths have survived beautifully, matching perfectly with the white tree bark they live on, until one day, a smoky building begins pumping its soot into the air. This air begins to change the color of the tree bark to black and the once hidden white moths are now plainly visible to birds who eat them easily. Fortunately, every now and then a moth is born who is darker than the rest - black as soot even. And so, the birds keep eating the white moths but missing the soot-colored ones. As time goes by, the soot-colored moths produce more and more similarly colored moths, who are well hidden from the birds AND after enough time, the only moths that remain are soot-colored. This is why so many species “fit” exquisitely into their environment. They have ALL adapted in some way similar to the soot-colored moth.

Which disorders can be observed in a human karyotype
s2008m [1.1K]

Answer:

Answered below.

Explanation:

A karyotype is defined as the size, shape, and number of chromosomes present in an organism.

An analysis is usually done on a karyotype to see if individuals have abnormal numbers or sizes of chromosomes. Such abnormalities may arise from;

Deletion: which implies that a chromosomal part is missing.

Duplication: where parts of a chromosome are repeated.

Translocation: which occurs when a chromosomal part breaks off and gets attached to another chromosome.

Nondisjunction: in which chromosomes do not separate from the parent cells.

Common chromosomal disorders arising from these abnormalities include;

Down's syndrome

Edwards syndrome

Turner's syndrome

Klinefelter syndrome

Prada-willi syndrome

Cri-du-chat syndrome

Patau's syndrome

The answer is withdrawal symptom. This is caused by the abrupt discontinuation or decrease in intake of medications or recreational drugs, in this case, alcohol.
