D = m/v ---> v = m/d
v = 3162 cm^3

Answer:
Meiosis produces haploid cells (gametes), which contain single chromosomes, or on-half the number of chromosomes in diploid cells. When a sperm and an egg join, the single chromosomes pair up, which results in genetic diversity in the offspring
Answer:
12.044 X 10^23 molecules of NaOH
Explanation:
because NaOH is an ionic bond, we should be asking how many <em>formula units </em> are in 2 moles of NaOH, there are 0 molecules since NaOH is measured in formula units.
but for the sake of the problem I'll assume NaOH is measured in molecules
for every mol of something there are 6.022 X 10^23 of something of that something.
so there are 6.022 X 10^23 molecules for every mol of NaOH
that means we have 2 X 6.022 X 10^23 molecules in 2 moles of NaOH = 12.044 X 10^23 molecules of NaOH
Answer:
The values of n, p and q are 314, 0.12 and 0.88 respectively.
Explanation:
n is the number of subjects given a placebo. The value of n is 314.
p is the sample proportion of the subjects given a placebo that developed headaches. The value of is 12% = 0.12
q is the sample proportion of the subjects given a placebo that did not develop headaches. The value of q = 1 - p = 1 - 0.12 = 0.88
Dalton's atomic theory proposed that all matter was composed of atoms, indivisible and indestructible building blocks. While all atoms of an element were identical, different elements had atoms of differing size and mass.
