What is the principle of natural selection?
The principle of natural selection is that the fastest or the strongest (in other words the most skill at a trait) would be the most desirable mate and the weak ones that lacked these skills or mutations like thumbs would not be mated with. So the principle of natural selection is we will always find the strongest, fastest or the most intelligent or other advanced traits more desirable.
Is osmosis a passive or active transport and how?
The four main kinds of passive transport are diffusion, facilitated diffusion, filtration and osmosis. Osmosis always deals with the movement of water across a semipermeable membrane. Water always moves toward the side that is higher in solutes (mainly salt). It does this to balance the two sides. Osmosis always follows salt is one of the best ways to remember this.
What is the angle of 50 percent grade?
50% grade = slope of 1/2 = (one half unit of rise)/(one unit of run) = arctan(0.5) = 26.565 degrees Check validity with tangent function: tan(26.565 degrees)=0.5 tan() function always gives you the slope, if you put in degrees. Arctan does the inverse.
