Living things are made of types of molecules, known as macromolecules.
There are four major classes of biological macromolecules:
carbohydrates
lipids
proteins
nucleic acids
Each of these types of macromolecules performs a wide array of important functions within the cell; a cell cannot perform its role within the body without many different types of these crucial molecules. In combination, these biological macromolecules make up the majority of a cell’s dry mass. (Water molecules make up the majority of a cell’s total mass.) All the molecules both inside and outside of cells are situated in a water-based (i.e., aqueous) environment, and all the reactions of biological systems are occurring in that same environment.
<span>The correct answer is Paramecia, Euglenoids, and Mold. These are all unicellular eukaryotic organisms. Mold may seem like one big piece but it's actually a bunch of unicellular organisms living together and constantly spreading over foor or similar things. They are most commonly predators.</span>
From several more prokaryotic cells.
Answer:
The best evidence for the three domain system is
Sensitivity to Antibiotics
Explanation:
The three domains of life includes :
Archaea - oldest known domain, ancient forms of bacteria.
Bacteria - all other bacteria that are not included in the Archaea domain.
Eukarya - all the organisms that are eukaryotic or contain membrane-bound organelles and nuclei.
Types of evidences for the three domain system are:
1) differences in the sequences of nucleotides in the cell's robosomal RNAs (rRNA)
2) the cells's membrane lipid structure.
3) its sensitivity to antibiotics.
That would be option A.
Good luck!
