True. Since electron microscopes use electrons instead of light, it can magnify up to 500,000 times of it’s actual size.
Organism, population, community (first choice)
I hope this helped out, have a nice day! :)
Explanation:
1. cell membranes are partialy permeable, only allowing passage to some certain molecules.
2. diffusion is the movement of molecules across partially permeable membrane down concentration gradient.
3. the molecules are too big to pass through partially permeable membrane. the concentration of the molecule might be higher in the cell than in the solution/surroundings.
The answers are: condense; visible
Explanation:
In Prophase I, the chromosomes condense and become visible.
- they are both found in the same place
- they are both passed down to newer generations
- both of them can determine your traits
