Protein
Proteins are the most versatile
macromolecules in living systems and they play important roles in essentially
all biological processes. Protein makes up the capsid of a virus. The infective
extracellular form of a virus known as a virion contains at
least one unique protein synthesized by specific genes in the nucleic acid of
that virus. In almost all viruses, at least one of these proteins forms a shell
(called a capsid) around the nucleic acid. Certain viruses also have other
proteins internal to the capsid. Some of these proteins act as enzymes during
the synthesis of viral nucleic acids.

Step by steps explanation
Answer:
Phloem sap.
Explanation:
A colloid is a combination of different types of molecules mixed through other substances that will not join (form a chemical bond) with the other substance.
Phloem sap is a mixture of water, carbohydrates, hormones and other type of substances flowing together but not bond by a chemical bond.
What is it called when lava cools and hardens? Sometimes magma flows upward and is forced out onto the earth's surface during a volcanic eruption. Magma that reaches the surface of the earth is called lava. When it cools and hardens, it too forms igneous rock. Igneous rock that is formed on the earth's surface is described as extrusive.n:
Answer:
The archaea and the bacteria both are prokaryotes. However, the genetic makeup of the archaea is more similar to the eukaryotes. Moreover, they have differences, in their metabolic pathways, genes and the enzymes possessed by them.
Explanation:
The differences between Archaea and bacteria:
1. The cell wall of the bacteria consist of peptidoglycan, while the cell wall of the archaea consist of pseudo-peptidoglycan.
2. The bacteria are capable of spore formation, which can lie dormant for long periods of time until a suitable condition is found for their growth. The archaea are not known to form such spores.
3. The genes of the archaea are more similar to the eukaryotes than the bacteria.
4. The bacteria are found everywhere where the living conditions are suitable (soil, air, living beings, non-living things). the archaea are capable of surviving in extreme conditions (hot springs, salt brine).
5. The bacteria use the process of glycolysis and follows Kreb's cycle for glucose break-down. The archaea do not undergo glycolysis or Kreb's cycle.
