Skin prevents the body from getting infections
Answer:
The correct answer is eukaryotes engulfed photosynthesizing prokaryotes
Explanation:
The endosymbiotic theory or symbiogenesis is an evolutionary theory that traces the origin of eukaryotic cells from prokaryotic organisms. It explains that some of the organelles (Mitochondria and Chloroplasts) in eukaryotic cells evolved from free-living prokaryotic microbes which were ingested or engulfed. The ingested prokaryotic cells survived within the organism and developed a symbiotic relationship.
According to the theory, chloroplasts was formed when eukaryotes engulfed photosynthesizing prokaryotes and mitochondria was formed when bacteria capable of aerobic respiration were engulfed.
Amoebas are single-celled organisms, which means that they are composed of just one cell. Each amoeba is a cell capable of performing all living functions by itself. They can reproduce asexually. They are protozoans with no fixed shape. Most have no hard parts and look like blobs of jelly.

Answer:
<h2>Liver, testosterone </h2>
Explanation:
The cholesterol is an important type of organic molecule that has many important roles in organisms. It is a sterol that is also called a modified steroid. It plays an important role in the cell membrane of the organism. Generally, it is synthesized in the liver and some other parts of the body. The synthesis of cholesterol is regulated by a homeostatic mechanism. Testosterone is synthesized from the cholesterol so cholesterol acts as starting material. Testosterone plays an important role in the development of the reproductive tissues of the male.
