This is false. First, men and women have different anatomies. A man cannot have diseases that involve female organs and vice versa. For instance, a man cannot have ovarian cancer simply because a man does not have ovaries. Second, there are some diseases that has gender predilection such as autoimmune disease (such as rheumatoid arthritis) more common in women and Parkinson's disease more common in men. Another is behavioral differences as a confounder. Men are more likely to have lung cancer because they have a predilection to cigarette smoking than women.
Your question is rather unclear but from what I can tell either there were not an even amount of Petri dishes or some of them were left open while others were not.
Answer:
6 offsprings with white fur
Explanation:
The gene involved here codes for fur colour in mice where the allele for brown fur (B) is dominant over the allele for white fur (b) i.e. the B allele will mask the expression of b allele in an heterozygous state (Bb).
Since allele B is dominant, in an heterozygous state (Bb), the mice will be brown-furred. Hence in a cross between two Bb parents, a phenotypic ratio of 1:2:1 will be produced where;
1 is BB (homozygous brown fur), 2 is Bb (heterozygotic brown fur) and 1 is bb (homozygous white fur).
Hence, 1/4 × 100= 25% offsprings will be white furred. If 24 mice result, 25/100 × 24 = 6 offsprings will be white.
Answer: some energy is lost from the pyramid, energy is transferred from bottom (producers) to top, but in decreasing amounts.
Explanation: total energy is conserved, but not necessarily within the energy pyramid, which is an open system where energy is lost from the pyramid, mainly as heat but also as sound.
Energy is transferred up the pyramid but the amount transferred at each stage is less because of losses outside the pyramid.
