Answer:
Barr bodies are small bodies that are dark staining bodies that show the inactivated X chromosome, these sex chromatin bodies attach to the membrane of the nucleus of interphase cells.
One less of the total number of X-chromosome (n-1) represents the number of Barr bodies.
Then,
The number of Barr bodies with Klinefelter would be:
Klinefelter (47,XXY): (n-1) = (2-1) = 1 Barr body as here two X chromosome present.
Similarly, for
Turner (45,XO): (n-1) = (1-1) = 0 Barr bodies (X chromosome = 1)
Now, as per the question, the bar bodies for karyotypes given
47,XYY: (n-1) = (1-1) = 0 Barr bodies
47,XXX: (n-1) = (3-1) = 2 Barr bodies
48,XXXX: (n-1) = (4-1) = 3 Barr bodies
Answer:
It must be large particles move into cells, unless there is another option
Explanation:
Passive transport does not require energy, so the first one is incorrect
Particles are moved from areas of high concentration to an area of low concentration, so the last one is also incorrect
So it should be large particles can move into cells, unless of course there is another option
Answer:
D)
Explanation:
Color is determined by a sex-linked gene, X gene, so, in order to that, the gene is maternally inherited. When one gene is related to the X chromosome, and one of the alleles is recesive and the other, logically dominant, the first generation will be of a single color, and the second generation will be of the other single color.
Energy that are not renewable can be
exhausted and the increasing use of internal combustion engines could eventually deplete petroleum.
<h3>What is petroleum?</h3>
Petroleum are fuel that are mainly produced from natural gas. This includes crude oil and some others hydrocarbons.
This fuel are used by vehicles, heavy machines to generate energy. The energy is a nonrenewable one.
Therefore, The increasing use of internal combustion engines could eventually deplete petroleum energy.
