Question on molecules? I am giving 2 molecules that are combined together by an oxygen atom I have a picture but i cannot post it here
I have to list what the molecue is

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.

i think the answer is a.keratin is the pigment responsible for skin color.
