Water is is less dense when frozen.
Why is carbon so important to forming organic molecules?
It bonds to nearly any...
"true," or "good." So "Prokaryotic" means "before a nucleus," and "eukaryotic" means "possessing a true nucleus." This is a big hint about one of the differences between these two cell types. Prokaryoticcells have no nuclei, while eukaryoticcells do have true nuclei. This is far from the only...

, within the cell. In exocytosis, a substance is enclosed by a membrane in a vesicle within the cell, and the membrane of the vesicle fuses with the cell membrane and releases the substance out into the cell's surroundings.

; have more heat production in the metabolism and more waste matter. But cells are small. Why? A small object has a relatively large surface area. Cells are small and so have a large surface area to volume. This is important because: The rate of exchange of material and heat energy is a function of its...

Prokaryoticcells divide by binary fission. Binary fission is a method of asexual reproduction involving the splitting of the parent organism into two separate organisms.

* The differences betweenprokaryoticcells and eukaryoticcells are that eukaryoticcells have (and prokaryoticcells don’t have):
1. a distinct, membrane-bound nucleus
2. membrane-bound organelles
transport proteins and protein pumps
Gives the cell membrane selective permeability
Ability to regulate substances entering and leaving the cell

between prokaryotes and eukaryotes is that eukaryoticcells contain membrane-bound compartments in which specific metabolic activities take place. Most important among these is the presence of a nucleus, a membrane-delineated compartment that houses the eukaryotic cell’s DNA. It is this nucleus that gives...
