Answer:

The electron microscope

Explanation:

<em>Fimbriae are very tiny appendages of about 3 to 10 nm in diameter found on the surface of most Gram-negative and some Gram-positive bacterial cells. They are mostly utilized as a structure to adhere to one another, to other organisms, or any other surfaces.</em>

Fimbriae generally contain adhesins, a virulence factor that facilitates adhesion to surfaces and <u>due to their tiny size, they can only be viewed using the electron microscope</u> - the scanning electron microscope to be precise.

Discuss ecology for a discovery and hypothesis driven aspect.
cestrela7 [59]

Answer:

Ecology refers to the scientific study of the associations between the organisms and the surroundings in which they thrive. Humans have always been witnessing and learning about the organisms and their surroundings around them. They have acquired many insights and deduced hypothesis on the basis of their observations.  

This is the aspect of discovery in the branch of ecology. Identically, there is an experimental scenario associated with the ecology that has been developed recently. This comprises formulating a hypothesis first and then examining it in the field or in the lab. Therefore, ecology utilizes the fundamental scientific procedure of hypothesis formulation and then examining and validating by the observations and experiments.
