Anna35 [415]

The question is incomplete. Here is the complete question.

Read each description below regarding the dual innervation of the ANS. Then click and drag each into the appropriate category base on whether it is an example of antagonic or cooperative innervation.

The sympathetic division stimulates mucus production by salivary glands while the parasympathetic division stimulates enzyme secretion.

The sympathetic division stimulates am increase in heart rate while the parasympathetic division stimulates a decrease in heart rate.

During sex, the parasympathetic division stimulates arousal while the sympathetic division stimulates orgasm.

The parasympathetic division constricts the pupils while the sympathetic division dilates the pupils.

Antagonistic:

Cooperative:

Answer: <u>Antagonistic:</u> The sympathetic division stimulates am increase in heart rate while the parasympathetic division stimulates a decrease in heart rate; The parasympathetic division constricts the pupils while the sympathetic division dilates the pupils.

<u>Cooperative:</u> The sympathetic division stimulates mucus production by salivary glands while the parasympathetic division stimulates enzyme secretion.; During sex, the parasympathetic division stimulates arousal while the sympathetic division stimulates orgasm.

Explanation: The peripheral nervous system is divided in <u>Somatic Nervous System (SNS)</u> and <u>Autonomic Nervous System (ANS)</u>. The first is responsible for sensory input and voluntary motion.

Autonomic Nervous System is divided into <u>Sympathetic and Parasympathetic divisions</u> and is controls the fight-or-flight and rest-and-digest situations. Usually, an organ with sympathetic and parasympathetic innervations have antagonic function, such as the heart rate -  one system causes the heart rate to increase while the other stimulates the rate to decrease. However there are cases in which the combination of the 2 systems cause an increase of stimulation, producing similar effects.

Analysing each category above, it is deductable that when the sympathetic stimulates mucus production and parasympathetic, enzyme secretion and when the parasympathetic stimulates arousal and sympathetic, orgasm, in both cases, they have cooperative innervation.

On the other hand, when sympathetic stimulates increase in heart rate and parasympathetic, decrease in the rate, as stated before, and one stimulates constriction of the pupils and the other, dilation of the them, those are examples of having antagonic innervation.

How does a prokaryotic cell such as bacteria differ from eukaryotic cells?​
LenKa [72]

Answer:

The main difference is that EUKARYOTIC cells <em><u>have</u></em> a nucleus while a PROKARYOTIC cell <em><u>does not</u></em>. Instead, prokaryotes have free floating genetic material.

Explanation:

To help you remember this distinction:

EU = YES eukaryotes <em><u>HAVE</u></em> a nucleus.

PRO = NO prokaryotes <em><u>DO NOT</u></em> have a nucleus.

I hope this helps and good luck with your assignment.
