Answer:

d. secondary structure ... hydrogen bonds

Explanation:

The secondary structure of a polypeptide corresponds to localized regions of orderly structure stabilized by hydrogen bonds between the backbone groups -NH and C = O and in which no hydrogen bonds involving the side chains participate. The secondary structure of the polypeptide is characterized by its ability to curl or fold, the folds being maintained by the polypeptide chains.

An action potential traveling along the entire length of an axon demonstrates ________ propagation.
Rudik [331]

An action potential traveling along the entire length of an axon demonstrates <u>continuous</u> propagation.

Propagation of action potential:

  • An action potential is created by the rapid input of Na+ ions and the slightly slower outflow of K+ ions.
  • Action potential initiation occurs in the axon's first segment, and as action potentials spread throughout the axon, cells can convey their output to synapses located further distant from the cell.
  • The action potential conducts continuously in unmyelinated axons, whereas it conducts rapidly and saltatorily in myelinated axons where sodium channels are concentrated near the nodes of Ranvier.
  • The action potential always advances in the same direction whenever a local current begins to form due to the prior axon segment still being in the absolute refractory period. As a result, action potentials travel away from the location of their generation and do not change course.

NNADVOKAT [17]

Answer:

The correct option is trial and error learned behavior

Explanation:

A trial and error learned behavior is a type of behavior in which an organism attempts to or tries something new which makes it (the organism) accept the reality of that thing or situation. This means that if the attempt is successful or pleasurable, the organism will attempt it again and if it's not, the organism will avoid that thing.

This is what was described in the question with the bird trying to eat the caterpillar but found it unpleasurable which made it to start avoiding it afterwards.
