Answer: b. Necton
Explanation:
Necton is the term used to refer to aquatic organisms that are able to swim against the current of the water they are in. For this reason they are called "actively swimming" organisms. Aquatic plants that are unable to move against the current are called Plankton.
Fish, whales and dolphins are able to move against the current and so are classified as Necton. It is worthy of note however, that some organisms are able to transition from Plankton to Necton as they mature.
The correct answer is: c. Mitochondria and d. Rough ER
Protein disulfide bonds are the links between the sulfur atoms of two cysteine amino acids of the protein and these bonds are part of the secondary and tertiary structure of proteins. Formation of disulfide bonds is very important for the folding and stability of some proteins. Disulfide bonds are mostly found in secretory proteins and lysosomal proteins because of their unstable state in cytosol.
