Hi there!
Active Transport - Through the use of ATP, active transport pumps molecules against a particular concentration gradient. Active transport occurs from a low concentration solute and moves to a high concentration of solute. Two examples of active transport would be endocytosis and exocytosis.
Passive Transport - Active transport is the movement of molecules down a gradient. Unlike passive transport, it goes from high to low concentration and does not require energy (such as cellular energy). Some examples would be osmosis and diffusion.
I hope this helped!

Answer:
The correct answers are: b) "An amyloid fibril is stabilized by hydrophobic interactions between aromatic residues", c) "Soluble proteins that misfold and form amyloid fibrils become insoluble", and d) "Because most newly synthesized proteins fold correctly, the accumulation of misfolded proteins (or fragments) tends to occur slowly, thus explaining the slow onset of disease".
Explanation:
Amyloid fibrils are protein aggregates that can cause pathological conditions, for instance, they are found in brain tissue in people with Alzheimer disease. This disease, and other relates diseases, have a slow onset because most newly synthesized proteins fold correctly and the protein aggregates are made up misfolded proteins. This newly synthesized proteins are soluble, but once the proteins are misfolded, they form amyloid fibrils that are insoluble. The amyloid fibrils are stabilized by hydrophobic interactions between aromatic residues, which are formed within the complex of insoluble misfolded proteins.

Explanation:
The best definition of recombinant DNA is the following: Recombinant DNA is the DNA that includes pieces from two different sources. It is the combination of genetic material , a process of <span>creating sequences that would not otherwise be found in the genome.</span>
