This active trypsin acts with the other two principal digestive proteinases — pepsin and chymotrypsin — to break down dietary protein into peptides and amino acids. These amino acids are essential for muscle growth, hormone production and other important bodily functions.
I believe the answer is:
Geosphere and hydrosphere
Biosphere and atmosphere
Hydrosphere and biosphere
Atmosphere and geosphere

Answer: An observation is something you sense: taste, touch, smell, see, or hear. An inference is something you decide or think about a thing or event after you observe it.
Examples: I observe that this shoe smells musty. (Observation) I infer that my teacher has a kid.
Answer:
E) a ''walking stick'' insect that resembles a twig
Explanation:
The cryptic coloration is a type of coloration that helps an organism to blend in its environment. With other words, it is a camouflage. This type of coloration has been developed by organisms that are prey, but also by organisms that are predators. The organisms that are prey use this type of coloration in order to hide themselves from the predators, to be as unnoticeable as possible, thus to avoid being attacked. The predators on the other hand, use this type of coloration in order to blend in with the surroundings so that they can come closer to their prey and attack it without being noticed. We can easily say that this type of coloration works in both of the ways. The ''walking stick'' insect for example, resembles a twig, thus it has a perfect camouflage to not be spotted and attacked. On the other hand we have the tiger with its stripes, which is an unusual coloration for a cat, uses its stripes to break up the outline of its body, thus making it either unnoticeable or it confuses the prey.
Protein. A chain of amino acids, known as a polypeptide chain, makes up a protein. Foods that contain protein include meat, dairy, eggs, soy, nuts, etc. Hope this helped :)
