How do you find the atomic mass/mass number of an atom? a. add the number of protons and electrons together b. subtract the number of protons by the number of neutrons c. subtract the number of protons by the number of neutrons d. add the number of protons and neutrons together

The answer is C subtract the number of protons by the number of neutrons and by the way both b and c are the same. ;)

sand 60

clay 10

silt 30

sandy loam should be dominated by the sand. as the amount of sand increased, the amount of slit needed to anchor the plants' roots to the sand will also be increased. even though the amount is very little, 10% part of clay is still necessary for proper oxidation.

this is a good question! i'll do some research and come back when i have the answer!
