Select all that apply. lipids
consist of fats, phospholipids, and steroids
include cholesterol and saturated fats
are primarily sugar and starches
are the most highly concentrated source of energy

The correct statements are:

Lipids refer to the biomolecule which is insoluble in polar solvents like water.

They are highly soluble in non-polar solvents.

They include fatty acids, sterols, waxes, fat-soluble vitamins (vitamins A, D, E, K), glycerides (mono, di, and tri), and phospholipids.

They perform various functions in a cell such as energy-storing compounds, signaling molecules, and structural component (like in cell membrane).

Oxidation of fats releases maximum energy (9Kcal per mole) as compared to carbohydrate and proteins which only release 4Kcal per mole.

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.

"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."
