Answer:
Since boron only has two electron shells, it is about as capable of gaining electrons as it is of losing electrons, so it behaves as a metalloid. The other elements in this group have more electron shells, so it is much easier for them to lose their valence electrons and they behave like metals.
The one who developed the culturing technique to enrich for a certain population of microbial cells from a complex community based on a particular metabolic phenotype of interest is Martinus Beijerinck. The correct option is C.
<h3>What is culturing technique?</h3>
Culture methods involve collecting samples from the field and culturing them to detect the presence of microbes.
The number of microbial species and their influence on corrosion are estimated. Culture media for various microbes have been established.
Culturing is simply the process of growing microorganisms in special media in the laboratory. It entails the preparation of sterile medium, as well as the inoculation, incubation, and examination of microorganisms.
Martinus Beijerinck invented the technique for enriching a specific population of microbial cells from a complex community based on a specific metabolic phenotype of interest.
Thus, the correct option is C.
