Answer:
Explanation:
Matter can change form through physical and chemical changes, but through any of these changes matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass.
Whales play an important role in stabilizing the aquatic food chain and reproduction of other species.
As more whales are killed the food distribution in the ocean becomes destabilized and causes changes in the food supply of many other kinds of marine life.
Whales are vital to the food chain, stabilising food flow and maintaining a healthy ocean.
As such, the rapidly decreasing whale population will have major effects on the ocean's ecosystem.
Believe it or not, whale poop also serves quite an important purpose to the ecosystem.
The correct answer would be A. All organisms are composed of multiple cells
Eukaryotic cells are cells that have a nuclear envelope, cytoplasmic organelles, and a cytoskeleton.
Prokaryotic cells are cells lacking a nuclear envelope, cytoplasmic organelles, and a cytoskeleton (primarily bacteria).
Also Eukaryotic cells have a nucleus in which the genetic material is separated from the cytoplasm.
Also Prokaryotic cells are generally smaller and simpler than eukaryotic cells; in addition to the absence of a nucleus, their genomes are less complex and they do not contain cytoplasmic organelles or a cytoskeleton
So the correct answer would be B.
Hope I helped.
