So the area is 2x3 cm with 68 paramecia.
Not sure if this is the best way to do it, but I’d do 68/2*3 (68 divided by (2 times 3))
So first 2*3 is 6cm.
Now you’re trying to find paramecia/cm2. You are trying to find a unit rate. That is a value over one.
Then because there are 68p and 6cm, to find the unit rate, you’d do 68/6.
Now you have your unit rate, which is 11.3 repeating, or 11 1/3 as a fraction.
That would be 11.3 (11 1/3) paramecia per cm2
also I’m not 100% sure if this is correct, just wanted to help, so no guarantees
Answer:
Passive transport is the movement of particulars across the membrane from area of <u>high</u> to an area of <u>low</u> concentration.
Explanation:
Passive transport is a transmembrane cellular transport mechanism characterized by the fact that it does not require energy.
What enables passive transport is the concentration gradient of a particle, which moves across the membrane from a site of high concentration to a site of low concentration.
Two known forms of passive transport are <u>simple diffusion</u> and <u>facilitated diffusion</u>.
Mitosis occurs after the G2 phase in the cell cycle.
Natural selection could not occur without environment, and a act on animal.
