Answer:
The molecular weight of calcium carbonate is 100 g per mole. 25 g of calcium carbonate corresponds to 0.25mole. 1 molecule of calcium carbonate contains three oxygen atoms. Thus, 0.25 mole of calcium carbonate will contain 0.75 moles of oxygen atoms which is equal to 0.75×6.02×10^23=4.51×10^23 oxygen atoms.

If a bacterium can divide once an hour, then after 5 hours, 1 bacterium will have yielded __________ bacteria.
If a bacterium can divide once an hour, then after 5 hours, 1 bacterium will have yielded 32 bacteria.
What is bacteria multiplication?Bacteria multiply with the help of a process called binary fission, which is a method of asexual reproduction in which a single bacterial cell divides into two halves, and each half of the bacterial cell develops into new bacteria.
Bacteria need moisture to grow so they thrive on high moisture foods such as chicken. Dehydrated or freeze-dried foods can be stored longer because the moisture has been removed while the food provides energy and nutrients for bacteria to grow.
For above given information, if bacteria divide into two in first hour, 4 in second hour, 8 in third, 16 in fourth and 32 in number in fifth hour.
Thus, if a bacterium can divide once an hour, then after 5 hours, 1 bacterium will have yielded 32 bacteria.

Answer:
none of the males or females could be colorblind, assuming that this question is referring to x-linked recessive inheritance patterns.
Explanation:
if it is an x linked recessive trait, then the male's genotype is, with (b) representing colorblindness and (B) representing normal vision. the female, who is h o m o z y g o u s for normal vision, would have the genotype.
It would be impossible for the dad to pass on his colorblind gene to a son, because he can only pass a Y chromosome to the son. and a daughter would get the colorblind gene, but the normal gene donated by the mom would dominate it so the daughter could not actually be colorblind
