Answer:
this question doesn't make any sense. where are the different parts that we're trying to match up?
External respiration (correct answer) involves the exchange of oxygen and carbon dioxide within the environment.
The exchange of wastes through the skin is just called excretion by sweating.
There is no exchange of nutrients that occur in the lungs but rather absorption of nutrients is the function of the gastrointestinal tract.
The exchange of oxygen and carbon dioxide within the cell is called cellular respiration and involves carrying oxygen from the blood to the cell then the cell uses it as the final electron acceptor in the electron transport chain. The metabolic wastes of the cell, primarily carbon dioxide, goes now to the bloodstream to be exchanged for oxygen in the lungs.
Answer:
The fish did not yet exist when the old layers of rocks were deposited. In fact, animals with hard parts did not evolve until about 600 million years ago, which is only about 13% of the 4.5 billion year age of the Earth. Multicellular animals without hard parts left tracks in older sediments, but had no fossilize-able body parts.
Explanation:
These are all true- Vacuoles might store food or any variety of nutrients a cell might need to survive but they can even store waste products so the rest of the cell is protected from contamination. They’re also larger in plants than in animals
Correct answer: A). Move away from one another
The divergent boundaries are formed when the tectonic plate move away from each other. It forms volcanic islands that occur when the plates move away in order to produce gaps that are filled by molten lava.
The divergent boundary contributes to the formation of seafloor spreading. When the plates that are made up of oceanic crust move away from each other, a crack in the ocean floor appears. Then the magma oozes out from the mantle to fill that crack that results in ocean ridges.
Hence, the correct answer would be option A.
