Answer:
b) heavy rains or fast-melting snow causes floods in many parts of the world.
Explanation:
"fast-melting snow" which is closer to "causes" is singular
I think it is C, because if I'm right present principal is something that is happening presently? If so, C would be the answer because they "are doing" the exercises right now in context.
<h2><u>Answer:</u></h2>
Transient measurable examination empowers you to analyze and demonstrate the conduct of a variable in an informational collection after some time (e.g., to decide if and how focuses are changing over the long haul.
Worldly explanatory strategies to follow nanoparticles in live cell would give rich data to surely know the biologic properties of nanoparticles in atomic dimension. Noteworthy advances in fluorescence microscopy procedures with high transient and spatial goals permit single nanoparticles to mark biomolecules, particles, and microstructures in live cells, which will address numerous principal inquiries in cell science.
Methods for observing the development of nanomaterials, for example, carbon nanotubes (CNTs), quantum spots (QDs), metal groups, upconver-sional nanomaterials, and polystyrene (PS) nanoparticles and so on in live cells. The organic properties of nanoparticles in live cells are likewise quickly abridged by fluorescence microscopy examines.
