Genetic disorders may be classified into three major categories: (1) single gene disorders, (2) chromosome disorders, and (3) multifunctional disorders or the complex diseases.
Two examples of each categories, still following the orders above are: (1) Huntington's disease and cystic fibrosis, (2) Down's syndrome and Jacobsen symdrome, and (3) heart diseases and variations of cancers.
Yah buddy let’s get this bread you know let’s go and the exam yah
Answer:
Options <em>A, B and C</em> are correct.
Explanation:
A. Nutrition impacts memory when people are on the diet for three months
This option is correct because it was found that being on a high- protein or high-fiber diet for three months resulted in a significant improvement on memory performance tests. Note that "significant" here refers to statistical significance- which means the result is not due to random chance.
B. Nutrition has a bigger impact on memory when people are on the diet for three months than when they are on the diet for one month
This option is correct because when subjects were on a month long diet of either a standard diet, high- protein or high-fiber diet, it was found that memory performance is somewhat better for the high-protein and high-fiber groups than for the control group, but the effect of nutrition is not statistically significant. This means that the subjects on the high-protein and high-fiber groups did not conclusively do better on memory tests, and the result could be attributed to chance or other extraneous factors.
On the other hand, when subjects were on a high- protein or high-fiber diet for three months, it resulted in a significant improvement on memory performance tests- which means the result was not due to random chance.
C. There is not sufficient evidence to conclude that nutrition impacts memory when people are on the diet for one month
This option is correct because as stated above, it was found that memory performance is somewhat better for the high-protein and high-fiber groups than for the control group, but the effect of nutrition was not statistically significant- which means the results could be attributed to chance.
<span>Puberty begins when the pituitary gland increase the amount of hormones in one blood stream. Puberty is the process of physical change during which a child body's mature and become transformed into an adult body which is capable of reproduction. The onset of puberty is characterized by releasing of different types of hormones, especially reproductive hormones into the blood stream.</span><span />
Answer:
Chromosomal inversion
Explanation:
Inversion is a type of mutation which occurs in the chromosome structure in which the chromosome region breaks at two points and the region between the break and rotates to 180°. The rotated region after rotation rejoins with the end of the chromosomes.
Sometimes these break occurs in the region of the gene and the inversion of the sequence of the gene proves a lethal mutation like in the case of haemophilia in humans.
Thus, Chromosomal inversion is the correct answer.
