Answer:
Option C is correct. The flow chart best shows the relationship between the cell structures is:
DNA → gene → chromosome → nucleus
Explanation:
DNA can be described as the material of inheritance.
A gene can be described as the basic unit of inheritance. It is made up of segments of DNA.
Chromosomes can be described as thread-like structures which are made up of different genes.
The nucleus is the site where chromosomes are placed. The nucleus is found in every eukaryotic organism.
Hence, the correct order for these cell structures is illustrated in option C.

An inactivated/killed vaccine is a vaccine consisting of either whole viruses or bacteria, or fractions of either, that have been grown in culture and then killed using physical (heat, or radiation) and chemical methods (usually formalin).
Explanation:
Virus: Measles vaccine, mumps vaccine, rubella ...
Bacteria: BCG vaccine, typhoid vaccine
It consist of integral proteins and trans-membrane proteins and peripheral proteins as well
Answer:
Animal ; prokaryote ; plant ; virus
Explanation:
Animal: An animal cell possesses cell membrane, ribosomes, lysosomes and nuclear membrane.
Prokaryote: In a prokaryotic cell, cell wall is present such as bacteria, ribosomes are present but nuclear membrane is absent
Plant: A plant cell possesses cell wall, ribosomes, nucleus and a large vacuole.
Virus: Viruses reproduces inside a cell because they do not have their own energy producing system, nucleus is absent but nucleic acid ( DNA or RNA) is present
