The correct answer is: halophiles
Halophiles on Greek means "salt-loving", so organisms that belong to this group are extremophiles (survive in extreme environment) that live in high salt concentration. Halophiles usually belong to Archaea, but can be found in Bacteria domain and sometimes even Eukarya.
Halophiles can survive on very salty environments (with a concentration of salt that is five times greater than the salt concentration of the ocean.
The cell would commit apoptosis. This is another term for cells committing suicide.
Answer:
Mitochondria and chloroplasts have their own DNA
Mitochondria and chloroplasts are surrounded by two membranes
Mitochondria are about the same size as most bacteria
Explanation:
The endosymbiotic theory, also known as symbiogenesis, is a theory that explains how eukaryotic organisms have been formed from prokaryotic cells. This theory holds that eukaryotic organisms originated from prokaryotic organisms that engulfed another prokaryotic cell, creating thus an organism with multiple membranes. In consequence, eukaryotic organelles, including mitochondria and chloroplasts, would have evolved from these prokaryotic endosymbionts. Moreover, both mitochondria and chloroplasts contain their own genes which are localized in a circular chromosome, thereby supporting an endosymbiotic origin of both organelles. Finally, bacterial cells have 1 to 10 microns in length, while mitochondria have a similar size, thereby also supporting an endosymbiotic origin of this organelle.
The following compounds can be classified as lipids: steroids, saturated fatty acids, phospholipids, unsaturated fatty acids.
WHAT ARE LIPIDS:
- Lipids are one of the four biomolecules in nature; the other three being proteins, nucleic acids and carbohydrates.
- Lipids are composed of long chains of carbon, hydrogen and oxygen. They are insoluble in water.
- Lipids consists of sterols, phospholipids, fats, triglycerides, unsaturated and saturated fats etc.
Therefore, the following compounds can be classified as lipids: steroids, saturated fatty acids, phospholipids, unsaturated fatty acids
