Answer 1

microbe that grow better at high C02 concentration - E. Capnophile

Justification: Capnophile are the microorganisms requires  the presence of high concentrations of carbon dioxide to grow.

Requires atmospheric oxygen, but in lower than normal concentrations- D. Microaerophile

Important source of energy, carbon, nitrogen and sulfur requirements in complex media - A. Peptones

Preservation method that uses quick-freezing and a high vacuum- C. Lyophilization

Generally contain ingredients such as sodium thioglycolate that chemically combine with dissolved oxygen - B. Reducing media

Justification: Sodium thioglycolate is reducing  agent which reduce molecular oxygen to water and create anaerobic condition in media which is called reducing media.
