A newborn baby dies soon after birth because her diaphragm and rib cage muscles failed to contract and she was unable to breathe
kozerog [31]

Answer:

Troponin

Explanation:

This is a complex of three proteins  (Trop C, I, T) that are responsible for muscle contraction of  the skeletal and cardiac  muscles . its binds with protein tropomysin  to lie in the grove between the actin filaments.  its prevents contraction by blocking  myosin crossbridge  in a relax muscles.Inorder to aid contractions  calcium ions binds with troponin, which leads to confrontational change.This exposes myosin on actin filaments,  leading to formation of crossbridge and therefore contraction of muscles.

Therefore if there is  a mutation in the gene that encoded Troponin, as explained above, calcium ion  will not be able to bind with tropinin, and there will be no exposure of myosin on actin filaments, no binding of  myosin on actin to cause crossbridge, and consequently no  muscle contraction,

Thus the intercoastal  muscle and diaphragm will not contract leading to death of the baby.

In ________ conditioning, an established conditioned stimulus is paired with a new neutral stimulus.
irina [24]

An established conditioned stimulus is paired with a new neutral stimulus in: higher-order conditioning.

Classical conditioning refer to a learning process that involves the repeated pairing of two (2) stimuli:

  • Conditioned stimulus.
  • Unconditioned stimulus.

Basically, classical conditioning is a learning procedure which helps psychologists in understanding when a neutral stimulus is paired with a conditioned response or a neutral stimulus and an unconditional stimulus.

Similarly, a higher-order conditioning involves pairing an established conditioned stimulus with a new neutral (the second-order) stimulus, in order to make the new stimulus elicit (bring forth) the conditioned response, without presenting the initial conditioned stimulus.
