Explanation:
Type of homeostatic mechanism in the human body which is most common is the maintenance of body fluids, dilute and solutions of water that carry liquefied chemicals found in internal part of the cell and the surroundings of them. the internal part of the cells, it is named as intracellular fluid, the external part of the cells, it is named as extracellular fluid. All the materials such as oxygen, nutrients, proteins, and ions, are needed for survival.
Answer:
German Zoologist discovers Theodor Schwann that animal were made from cell
Cyanobacteria don't need oxygen to survive they produce oxygen. They where the first ever known organisms on the planet and they produced oxygen in the oceans which was absorbed by iron deposits and then once the iron had oxygen the ocean got the oxygen until it got into the atmosphere and Eukaryota bacteria evolved. So the answer would be: <span>They convert nitrates from the water into nitrogen gas (N2) that is released into the atmosphere.</span>
Answer:
d. secondary endosymbiosis.
Explanation:
- When a living cell acquires another organism that eventually becomes a part of this cell, this process is known as primary endosymbiosis.
- When an organism that has already undergone primary endosymbiosis engulfs another eukaryotic organism then this process is known as secondary endosymbiosis.
- Secondary endosymbiosis has been known to occur in plastids because of which they are surrounded by two membranes. This bilayer is present because one of the layers is the original outer membrane of the organism and the other membrane is that of the organism that has been engulfed.
