Prokaryotes don’t have organelles (which are the cell’s ‘organs’ that carry out the cells functions).
Plant cells and animal cells are eukaryotes because they have organelles.
Plant cells are kind of stiff because of their structure. They have a cell wall, which is really tough. Also, plant cells perform photosynthesis, using an organelle called a chloroplast. Finally, plant cells have a large vacuole that stores the cells waste.
Animal cells, unlike plant cells, lack a cell wall. That means they’re free to wiggle if they wanted to. Animal cells have lysosomes that assist in reproduction.
“Populations evolve through a process known as natural selection which allows individuals with beneficial traits for survival to breed with other individuals who share those traits, eventually leading to offspring who only exhibit those superior traits.” -from: https://www.thoughtco.com/only-populations-can-evolve-1224608

C. To give short bursts of energy to muscle cells
Answer:
peptide bonds are created during the formation of the primary structure
Explanation:
The primary structure of a protein is the amino acids sequence of a protein or polypeptide chain, is the linear sequence of the protein . The amino acids are joined by peptide bond or amide bonds, this is the reason of the name polypeptide.
Carboxylic acid and an amino group form the peptide bond by the loss of a water molecule. The peptide bond is a covalent bond. It forms a relatively rigid unit. It´s synthesis is an enzymatically process carried out and controlled by the ribosome.
The characters of the peptide bond have influence on the flexibility and stability of polypeptide
