Answer:
Active transport requires energy from ATP while facilitated diffusion does not
Explanation:
Active transport and facilitated diffusion with the use of channel and carrier proteins are both ways by which ions, polar and large molecules cross a selectively permeable membrane.
The major difference is that; Active transport transport these particles from a low to high concentration, which is against concentration gradient and hence, energy is required to perform the task
Facilitated diffusion transport from a high to low concentration, which is through a concentration gradient and hence, no energy is required to perform the task.
1. Chromosome condense (Prophase)
2. Spindle fibers form (Prophase)
3. Chromosomes allign in the center of the cell (Metaphase)
4. Chromosomes separate (Anaphase)
5. Cell membrane pinches (Telophase and Cytokenesis)
6. Spindle fibers disappear (Conclusion of Cytokenesis)
It is true that it is possible for a population to not evolve for a while.
There is something called the Hardy-Weinberg theorem, which characterizes the distributions of genotype frequencies in populations that are not evolving.
There are 5 Hardy-Weinberg assumptions:
- no mutation
- random mating
- no gene flow
- infinite population size
- and no selection (natural nor forced).
You can see that some of these are kinda extreme and really hard to get, but with approximations, we can work.
For example, instead of an "infinite population size" we have enough with a really large population, such that genetic drift is negligible.
Concluding, yes, it is possible (but really difficult) for a population to not evolve for a while (at least, in nature), as long as the 5 assumptions above are met.

The correct answer for both blanks is "Sodium".
Sodium ions are necessary in small quantities for some sorts of flora, but sodium as a nutrient is extra usually wanted in large quantities by using animals, due to their use of it for era of nerve impulses and for upkeep of electrolyte balance and fluid stability. In animals, sodium ions are vital for the aforementioned capabilities and for coronary heart hobby and sure metabolic functions.
