Explanation:
Stimulus in biology can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). Thus, all living organisms (both animals and plants) respond to changes in their environment and consequently, an appropriate response or reaction is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.
In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ. Therefore, the senses are necessary for behavior because stimuli must be sensed in order to respond.
Stimulus control can be defined as a phenomenon that arises when a living organism responds or behaves in the presence of a stimulus and in another way in the absence of a stimulus.

The doctor feels the need to intervene in the baby's birth as the baby will not be able to breathe and the umbilical cord will squeeze the baby and will choke it.
<h3>What is labor?</h3>
Labor is a process that happens during the progressive contraction at the time of birthing a baby through the cervix of the uterus. When the baby's position gets changed and struck during the concentration forceps are used to guide the baby.
The baby's birth should be intervened in case of an emergency because the umbilical cord may squeeze the baby and will make it oxygen deficient. The bones may also get fractured resulting in damage to the nerves and causing disability.
Therefore, the baby's birth should be intervened.
