First, you should know that selectively permeable is anexpression that defines the property of a membrane that allows some molecules to croos in and out it but not others. A sentence that you can use to let this term clear is that " slectively permeable or the croos of a membrane by only some substances but not other is the process that underlyas osmosis"

Briefly, one can categorize the 3 types of boundaries as so: At convergent boundaries, the two tectonic plates are coming closer to each other; at divergent boundaries they are increasing they move away from each other and at transform boundaries the plates are moving parallel to their boundary. Based on this, all boundaries will be divergent boundaries.

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: Antagonistic: 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.

Cooperative: 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 Somatic Nervous System (SNS) and Autonomic Nervous System (ANS). The first is responsible for sensory input and voluntary motion.

Autonomic Nervous System is divided into Sympathetic and Parasympathetic divisions 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.

Having the occasional alcoholic drink is unlikely to affect your fertility. But heavy drinking and smoking can reduce sperm quality, lower testosterone production, and make it harder to achieve an erection. It can also lead to liver damage, which affects both your general and reproductive health
