The difference between the two is simple diffusion moves molecules downwards instead of upwards and infacilitated diffusion is the opposit, simple diffusions also can be passive (no clue if that makes sesnse) but facilitated diffusion is a more active process requiring energy you could technically look this up for the answer and find the same thing just more explained.
the media says:
"In simple diffusion, molecules move down the concentration gradient but <span> molecules move up the concentration gradient. </span>Simple diffusion<span>is passive but </span>facilitated diffusion is an active process that uses energy."
all u have to do is look up "<span>Simple diffusion and Facilitated diffusion" and right at the top itll give u an answer</span>
The potential energy in food is what we call a Calorie, which (note the capitalization) is actually a kiloCalorie (1000 calories). Just pick any food high in calories; fats and oils are very calorie dense.
Significant figures<span> tell us how to round, but they also make sure that the answer we get from a math problem is not more precise than the numbers that we started with. </span>
<span>B is the correct answer. The beginning of DNA replication occurs with the unwinding of the DNA helix by a special enzyme. The two strands that form the helix then create a replication fork. The two strands are then oriented differently, one becoming the 'leading strand' and one the 'lagging strand'. </span>
The α-amino group of many amino acids is transferred to α-ketoglutarate to form glutamate, which is then oxidatively deaminated to yield ammonium ion (NH4+).
