c. By brine curing

Explanation:

Tanning refers to the process of treating the hides and skins of animals to produce leather.The different processes involved in the tanning of leather include:

Curing: this is the process of applying salt to the animal hide to prevent decay  from bacterial growth. It also serves to reduce the moisture content of the animal hide.

Soaking : this involves soaking the hides in clean water to remove the salt left over from curing and increase the moisture content for further treatment of the hide.

Liming: Liming is done by applying lime to remove hair, fat and grease and in order for the hide to swell up.

Scudding: This is the process of further removal of usually done first by a machine, and then manually using a dull knife.

Deliming: This is done using an acid to reduce the pH of the collagen found in the hide being tanned.

when atmosphere interacts with biosphere they focuses on on the sources and sinks of green house gases (ghgs) air pollutants, particular matters, water and energy between the earth's surface and the atmosphere. the biosphere affects the climate. the atmosphere and biosphere are in constant interaction with each other, and all living things rely on gases in the atmosphere for life. organisms such as animals take in oxygen gas form the atmosphere to use in every cell of their body for smooth functioning of daily routine exercises.
