"In plant cells, the vacuoles are much larger than in animal cells. When a plant cell has stopped growing, there is usually one very large vacuole. Sometimes that vacuole can take up more than half of the cell's volume. The vacuole holds large amounts of water or food."</span>
A) The answer is allosteric interaction where activators or repressors bind to a protein, other than the protein active site, hence changing the protein conformation. This interaction occurs between the heme subunits of haemoglobin.
b) Through protonation. The amino group of the alpha subunits and the histidine C-terminal of beta subunits acquire H+ when the blood has low pH. Low pH in the blood is due to accumulation of carbon dioxide and consequent formation of carbonic acid. Protonation of the residues cause allosteric interaction, due to ionic interaction, of the subunits hence resulting to conformation change of haemoglobin between T-state and R-state
I believe the appropriate answer is, short amino acid chains, NAG, NAM, and some lipid proteins.
Peptidoglycan is also known as Murein, it is a polymer consisting of sugars and amino acids that form a mesh-like layer outside the plasma membrane of most bacteria, forming the cell wall. The sugar component consist of alternating residues of β-(1,4) linked N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM),

nerves. The fovea is responsible for the higher visual acuity 20/20 vision. It
is the region if the retina that is depressed and has little blood vessel
supply to avoid dispersion of light. While it only comprises 1% of the
retina, it makes up 50% of brain’s visual cortex. </span>
Answer:
Explanation:
Fish- Gills, allows to breathe under water
Shark- Small receptors on their heads allow for magnetic field sensing
Beavers- Slaps their tails when a animalgets close to their dam
Shrike Bird- Catches bugs and sticks them on thorns to impress potential mates
Birds Beaks- Birds have adapted to eat many different foods, their beaks show what kind of food they eat
