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 name sounds male so that should be right.
There are 23 pairs of chromosomes in each cell in a normal adult human.
Prediction! hypothesis consists of very little evidence. kind of like a guess
The two events that occur when gravity causes a nebula to collapse into itself are:
A. Nuclear fusion start.
B. A new star forms.
Explanation:
- Nebula are giant clouds of dust and gases.
- These clouds are considered as progenitors of stars and planets.
- The gravitational pull within these giant clouds result these large masses to collapse towards their centre.
- The gravitational collapse results in tremendous rise in temperature till a point where nuclear fusion begin .
- The stars are born out of such mechanism and act as a source of heat and light in universe.
