There's a block of metal with the dimensions below that weighs 2500 grams. What is the density of the metal?

The correct answer is 37.72 g/

Explanation:

To find the density of this block the first step is to find the total volume or space occupied by the block. This is because the volume is one of the factors that determines density (Density = mass ÷ volume). Now, to find the volume multiply the three sides given or the length, width, and heigh:

6 cm × 3 cm × 4 cm = 72

Finally, calculate the density:

2500 grams ÷ 72 cubic centimeters = 37.72 g/

his research revealed two genetically different groups of prokaryotes, which justified splitting kingdom monera into two kingdoms. the genetic and cellular differences were so great, that these two kingdoms were eventually placed into different domains in the current three-domain system.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
