Answer:
Salmonella are made of Flagella which prevent it from being phagocytosed.
Flagella is a long filamentous organelle responsible for bacterial motility. falgella are present exteranlly in all three dimensionally in salmonella and it helps salmonella to swim in liquid conditions and rotates the flagella on firm surfaces.
Flagella is known as PAMPs (pathogenic molecular patterns) in salmonella which is used by the host to identify bacteria and activate the immune system of the bacteria.
Hence, rotating or motility and immune function of flagella in salmonella prevent it from being phagocytosed.
Carbon has 4 valence electrons and is great at covalent bonding to share those electrons, giving us long carbon chains.
Answer:
<h2>homoplasy</h2>
Explanation:
Homoplasy: the character that is present in the set of species but not present in their common ancestors is known as homoplasy. In case of an archaean cell, their rRNA sequence is more similar to that of humans than the sequence of mouse rRNA is to that of humans.
Example: the evolution of the eye which has originated independently in many unrelated species.
Without further context I would assume the answer here is: Hydroxyl groups.
