Answer:

Their cell walls are composed of very different biochemicals.

Explanation:

Biological classification is important to classify the organisms on the basis of their similarities and differences between them. Linnaeus is known as the father of biological classification.

Cellwall plays an important role in the maintenance of structure and function of the organisms. The composition of the cell wall of fungi, plants and prokaryotes are quite different. Plants cell wall made of cellulose, fungi has chitin in its cell wall and prokaryotes has different layers of cell wall.

Thus, the correct answer is option (D).

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 cystic fibrosis affect meiosis?
Anna007 [38]

Answer:

The defective CFTR protein changes ion influx and efflux across the body's cell membranes, which ultimately changes the internal environment of these cells. This change contributes to each cell's production of proteins through transcription and translation.

What is the advantage to prokaryotes grouping related metabolic gene products into a single operon
ANTONII [103]
The advantage to prokaryotes grouping related metabolic gene products into a single operon is they only needed one mRNA to create several gene products. This makes a prokaryote different to a eukaryote in terms of gene information processing. Prokaryotes have fewer genes. These genes are located in one chromosome only.
