Globular proteins fold up into compact, spherical structures that have uneven surfaces. they tend to form multisubunit complexes, which also have a rounded shape. fibrous proteins, in contrast, span relatively large distances within the cell and in the extracellular space. which protein is not classified as a fibrous protein? (a)elastase (b)collagen (c)keratin (d)elastin

Elastase.

Explanation:

Collagen, keratin, and elastin are fibrilar proteins.  

Elastin is a globular protein, actually an enzyme, that breaks down proteins, such as elastin. It is a protease. In humans, there are eight different genes for the production of elastase. Elastase also has an important immunological role .

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.
