The microscopes available for scientists use nowadays have the capacity to magnify objects to a great extent, as much as two millions times. This has made it possible to study the cell structures in greater details and to have more precise knowledge of the reactions that occur in cells, this automatically leads to amendments and revisions of the previous findings.

The pathogen replicates without using host cells replication machinery, and it is directly transmitted

Explanation:

We could infer that the disease is caused by bacteria, as we know that it can be cured by using antibiotics. Antibiotic a group of drugs capable of destroying bacterias or inhibit their growth.

Bacterias have many different ways of propagating, one of them is by contact:

Direct contact: This occurs when people touch or kiss a sick person, or there is an interchange of liquids and corporal fluids (such as sweat or blood) between the healthy person and the sick person.
Indirect contact: the transmission occurs through an object.

Bacterias do not need any other living being to reproduce and they are able to survive under extreme conditions. Bacteria do not need any host to replicate.

In the exposed example, the disease is cured by using antibiotics, and its transmission is by direct contact, such as handshaking or touching.

How are science and technology related

o-na [289]
