The digestive system uses mechanical and chemical methods to break food down into nutrient molecules that can be absorbed into the blood. Once in the blood, the food molecules, including fat molecules, are routed to every cell in the animal's body.
Answer:
Prokaryotes.
Explanation:
Most of the Eukaryotes most likely to evolve from the Prokaryotes. Prokaryotes are basically unicellular organisms that lack internal membrane-bound structures. So, they do not carry nucleus and generally have a single chromosome. Most of them have a cell wall outside the plasma membrane, which is a thin layer of lipid that completely surrounds the cell. Prokaryotes reproduce by binary fission method.
The ocean life would die off because less salinity in the water and if the currents decrease in strength the nutrients they carry would not make to the life in the oceans and ocean life would die.
10 - the density is less than air.
11 - higher-viscosity. can't explain - sorry
The second choice.
Archaean biochemistry is more similar....etc.
