Virulence factors of virus aids in its ability to infect cells.
Explanation:
Virulence factors help pathogenic microbes to infect host cells by virulence mechanisms – invade host, cause and spread disease, evade the defense or immune mechanism of the host. These factors makes the virus to grow, replicate, and modify the host cells due to its toxicity.
Viruses binds to the receptor protein of the host cell.
Different types of virulent factors are: invasion factors, adhesive or adherent factors, capsules, endo and exotoxins, etc.
The virulence factors decides the severity and rate of spread of an infection

Answer:
There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids); each is an important cell component and performs a wide array of functions.
Explanation:
The energy flow within an ecosystem.
Animals can utilize both radiant and fixed energy. The fundamental unit of electromagnetic waves like light is radiant energy. Fixed energy is chemical potential stored in various organic materials that can be damaged to release their energy.
Autotrophs are organisms that can fix radiant energy and can synthesize organic compounds from inorganic materials. Heterotrophs are organisms that cannot receive energy from an abiotic source but rely on organic compounds produced by autotrophs that are rich in energy.
