Smita wants to find new ways to recycle materials. which field of study would be most useful to her? a. meteorology b. chemistry c. microbiology d. zoology

Option B

Explanation:

The chemical properties of a material play a very important role in recycling and reusing any thing.

For instance - if a plastic on melting transforms into a form which cannot be re-converted into its original form, then such plastics are not reusable materials

A recyclable material must be able to regain its original molecular structure and size though physical processes such as heating, melting, remolding etc.

hence, option B is correct  

wait any answer choices plz

answer: the correct option is d. enzyme

lactase and carbonic anhydrase are the examples of enzymes.

lactase is an enzyme, which is present in the small intestine of mammals. it in the digestion of the disaccharide, lactose ( milk sugar) by converting it into two monosachharide, which are glucose and galactose.

carbonic anhydrase is present in the red blood cells. this enzyme plays significant role in the transport of co₂. it in the conversion of co₂ and h₂o into carbonic acid, which is then dissociated into bicarbonate ions and hydrogen ions.
