Answer:

Virus are small infectious particles which act as intracellular parasites. They are considered non-living when they are present outside their host because they show no metabolism outside.  

They do not have even cellular level of organization and are basically just packages of nucleic acid and protein. Still, virus have some important features which are common with cell-based life like the presence of nucleic acid as their genetic material.  

Apart from the presence of genetic material they also have the ability to evolve like the cell-based life. This evolution allows them to be selected naturally and produce more offspring.

Licemer1 [7]

A batsman is unlikely to score a century in every cricket match. This is an example of "partial reinforcement".

<u>Option: C</u>

This method of arranging reinforcement is also called intermittent reinforcement after certain number of correct answers or certain interval of time.

Can molecules made from the same atom form ionic bonds. Why?
Digiron [165]
No. Ionic bonds form when atoms with opposite charges bond with one another. Atoms develop charges by gaining or losing electrons. For a given element, the atoms will (usually) have a tendency to gain OR lose a particular number of electrons, so they can only form ions of a particular charge that is either positive or negative.
