Answer:
p = 0.36
q = 0.64
p² = 0.13
2pq = 0.46
q² = 0.41
Explanation:
We need to use the Hardy-Weinberg equations:
p + q = 1
p² + 2pq + q² = 1
p: the frequency of the dominant allele
q: the frequency of the recessive allele
p²: the frequency of homozygous dominant
2pq: the frequency of heterozygous
q²: the frequency of homozygous recessive
Here, we know that 328/800 people are homozygous recessive, which means that q² = 328/800 = 0.41.
Then, q = √0.41 = 0.64, and p = 1 - q = 1 - 0.64 = 0.36.
Now, we have p² = (0.36)² = 0.1296 ≈ 0.13 and 2pq = 2 * 0.36 * 0.64 = 0.4608 ≈ 0.46.
The answers are:
p = 0.36
q = 0.64
p² = 0.13
2pq = 0.46
q² = 0.41
Answer: option b - 55
Explanation:
Menopause signifies the time in a woman's life when menstruation ends, usually BETWEEN age 45 - 55.
And because of the crucial role played by Oestrogen in menstruation, its LOSS increases the RISK of HEART DISEASE seen in women AFTER MENOPAUSE .
I believe the correct answer from the choices listed above is option B. Aging effects all of the body's cells; and therefore, the basic building blocks of tissues. As your body ages, many tissues lose mass resulting in atrophy. <span>Organ </span>Atrophy<span> is a decrease in the tissue mass of an organ due to either a decrease in size of individual cells (cellular </span>atrophy<span>). Hope this answers the question.</span>
Answer:
The culture might not be stained properly or the culture might be too old.
Explanation:
Gram staining is done to differentiate between gram-positive and gram-negative bacteria according to the difference in their cell wall. In gram staining, the gram-positive bacteria appears violet and gram-negative bacteria appear pink in color.
Therefore if a pure culture contains have both red and purple cocci that it can be concluded that the gram stating was not done properly like too much destaining was done or too much safranin was used or maybe the culture is too old so that cell wall of some bacteria degrades.
