The fight or flight response is most likely because of stress as this response usually occurs or happens when an individual is experiencing stress and when he or she is likely exposed to stimulus that will result the person to feel stressed and worn out.
Answer:
add a water molecule to break bonds.
Explanation:
Fat digestion occurs in the small intestine where pH is alkaline. Protein digestion starts in the stomach at acidic pH but is completed in small intestine under the conditions of alkaline pH. Both processes use water molecules to break the covalent bonds of the nutrients. Peptidases present in small intestine add water molecules to the peptide bonds that join two amino acids together. This releases the individual amino acids from peptides. Similarly, the enzyme lipase adds water molecules to break the covalent bonds between fatty acids and glycerol of lipid droplets.
Answer:
A) few B) 100% c) 100%
Explanation:
Muscle responds a stimulus which is capable of generating action potential. Muscle response is in a way of "ALL or NONE". Muscle response to greater stimulus by recruiting more muscle fibers.
A) At threshold there would be only a small proportion of muscle is contracting.
B) At maximal stimulus the maximum number (100%) of recruitable fibers are contrating.
C) The number of recruitable fibers can't increase above maximal stimulus because already the maximum number of recruitable fibers are contracting.
