In a village, if the proportion of individuals who have sickle-cell disease is 0.50, and the population is assumed to be at Hardy-Weinberg equilibrium, what is the expected frequency of
the HbS allele? (Hint: What is the genotype of people with sickle-cell disease, and how is that
genotype represented in the Hardy-Weinberg equation?)
A.0.125
B.0.25
C.0.5
D.0.71

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.

the answer to your question is tooth decay.

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
