Answer:
Sympathetic nervous system
Explanation:
The sympathetic nervous system of the autonomic division prepares the body for stress or emergency conditions by generating the “fight-or-flight” responses. The sympathetic nervous system triggers the release of stress hormones from the adrenal medulla to generate the set of physiological responses.
There is dilation of the pupil, and an increased rate of heartbeat and increased blood pressure. Other responses include dilation of airways and dilation of blood vessels that supply blood to skeletal muscles, heart muscles, liver, etc. Under the given emergency condition, the sympathetic nervous system of Meghan was activated to generate the fight or flight response.
<span>The nitrogenous base pairs, which are linked by hydrogen bonds that also hold the strands together, are between this backbone. However, the nitrogenous bases, which are adenine, thymine, cytosine and guanine, pair up so that cytosine only pairs with guanine and adenine links up with thymine.</span>
Adaptation is a response to the environment but long term.
For example:
<span>A wolf has a fur coat as an adaptation to the cold weather, but birds migrating south is a response to cold weather.</span>
thats the plasma membrane. its the outside of a cell :)

The given question is incomplete as it does not have the options which are:
a) Sensory receptor
b) Sensory neuron
c) Motor neuron
d) Effector
e) Integration center
Answer:
The correct answer is option-Effector
Explanation:
A reflex arc is the mechanism of the neurons which controls the reflex action or involuntary responses or the instantaneous responses of the organisms.
The reflex arc involves the sensory receptors, sensory neurons (transmit signals from sense organ to spinal cord), motor neurons (transmit signals from spinal cord to muscle), Integration centre in the spinal cord and effector.
An effector represents the gland or the muscle which receives the transmitted signal from the motor neuron and responds by showing movements.
Thus, option-Effector is the correct answer.
