"Cells are so little, so they can maximize their ratio of surface area to volume. Smaller cells have a higher ratio which allow more molecules and ions move across the cell membrane per unit of cytoplasmic volume. Cells are so small because they need to be able to get the nutrients in and the waste out quickly."
Answer:
Anaphase
Explanation:
During Anaphase the chromosomes separate and move along the spindie fibers to opposite ends of the cell.
<span>With an enzyme, the activation energy of the reaction decreases, which increases the reaction rate.

Electric motors transform electrical energy into mechanical energy so the answer would be B.
Explanation:
Answer:
1. Iterative homology: e.g. antenna and leg of fiddler crab
2. Ontogenetic homology: e.g. radular teeth of veliger, feathers of chicken and hen
3. Di-polymorphic homology: e.g. white and brown feathers of hen races, chelae of male and female of fiddler crabs
4. Supraspecific: e.g. chelae of fiddler crab, chelae of lobster, feathers of hen and pheasant
