Which part of a feedback mechanism receives messages from several
sensors, compares actual conditions to set points, and determines whether
there are differences from set points?
oa) effector
ob) stimulus
oc) response
od) integrating center

D. Integrating Center

Explanation:

To maintain homeostasis in the body, the body needs to keep track of the condition within and respond to any fluctuations. Also known as the control center, the integrating center activates the effector when it sees that values of the internal condition of the body deviates from the normal range. When this happens, the effector will cause a response to get back within normal range.  

The process of translation or protein synthesis stops when the tRNA binds to any one of the three codons that are UGA, UAG or UAA.

These do not code for any amino acid therefore they send the signal for protein termination. The stop codon in the A site forces the peptidyl transferase to add the water molecule in the presence of release factors.

This frees the carboxyl end of the protein which holds the protein attached to the ribosome, therefore, the synthesised protein at that time is released into the cytoplasm.
