Answer:

A: Cumulative recorder

Explanation:

B. F. Skinner was a psychologist, author, behaviorist and inventor of Operant conditioning chamber and Cumulative recorder.  The purpose of cumulative recorder was to study the rate of operant conditioning. It is a process in which behavior of an organism is modified or an organism is conditioned to perform a specific behavior through giving punishment or reward.

For example: We teach a kid that he should not touch a hot stove because it will burn his hands, or we give him a box of candies to perform a specific task or behave in a certain way. Skinner used Cumulative recorder to find the effect of certain factors on behavior or response of an organism For example: the rate at which lever was pressed by a monkey to get bananas etc.

What happens to contraction of a muscle cell if some of the Ca2+ that was released during a contraction is still in the cytoplas
Kazeer [188]
<h2>Muscle contraction in cytoplasm </h2>

Explanation:

  • Calcium stays in the sarcoplasmic reticulum until discharged by an improvement. Calcium at that point ties to troponin, causing the troponin to change shape and expel the tropomyosin from the coupling destinations. Cross-connect stick proceeds until the calcium particles and ATP are never again accessible.
  • ATP is basic to get ready myosin for official and to "revive" the myosin.
  • When the actin-restricting destinations are revealed, the high-vitality myosin head overcomes any issues, framing a cross-connect. When myosin ties to the actin, the Pi is discharged, and the myosin experiences a conformational change to a lower vitality state. As myosin consumes the vitality, it travels through the "power stroke," pulling the actin fiber toward the M-line.
