Proteolysis is the process in which proteins are destroyed in eukaryotic cells. Lysosome plays an important role in protein degradation. During starvation, the long lived proteins are being destroyed for the source of energy.
If the protein degradation is not aided by lysosome then there is another pathway for degradation of proteins in eukaryotes and is Ubiquitin based degradation. Protein degradation also occurs if a faulty protein is been formed to eliminate the consequence of the protein formed by mistake.
Land mammals became more common in the Quaternary period, which came after the Neogene, so the first statement is not true.
FIrst whales evolved 50 million years ago and the quaternary period began 2,6 years ago, so the first whales did not evolve during this period.
The quarternary period is famous for its ice ages, so the Earth did not heat up during this period.
There was indeed a rise in the ocean levels during the Neogene period, so this is a true statement

Explanation:
A bacterium called Vibrio cholerae causes cholera infection. The deadly effects of the disease are the result of a toxin the bacteria produces in the small intestine. The toxin causes the body to secrete enormous amounts of water, leading to diarrhea and a rapid loss of fluids and salts (electrolytes).
