Answer:

The correct answer is the composition or components of the cell wall (if present).

Explanation:

The common component of all three domains, Archaea, Bacteria and eukarya, is cell wall composition (if present), Archaea cell wall has peptidoglycan, whereas the Eukarya cell wall has polysaccharides (if present). Bacteria cell contains neither polysaccharides nor peptidoglycan in their cell wall.

Thus, The correct answer is composition or components of the cell wall (if present).

Based on the data, what is the probability a randomly chosen cell will be observed undergoing cell division? You may use the cal
dexar [7]

Answer:

A

Explanation:

<em>The active state of cell division covers the prophase, metaphase, anaphase, and telophase. The total number of observed cells that were undergoing cell division can, thus, be calculated by adding the number of cells in each stage of the cell division.</em>

Total number of cell in division = 20+4+2+4

                = 30

Probability that a randomly chose cell will be undergoing cell division = <em>number of cells in division/total number of cells</em>

     = 30/200

          = 0.15 or 15%

The correct option is, therefore, A.

A specific atom of molybdenum has an atomic number of 42 and a mass number of 96. How many protons are in this atom of molybdenu
Masja [62]

Answer:

42

Explanation:

The mass number of an atom is equal to the number of protons plus the number of neutrons in a nucleus  

This atom Mo-96 has an atomic number of 42 and so has 42 protons in the atom.

My name is Ann [436]

Answer:

The part of your nervous system that is similar to the autopilot of the airplane is the autonomic nervous system

Explanation:

The autonomic nervous system is regulated by the hypothalamus which in turn controls functions such as digestion, urination and other unconscious functions.

<h2>What is a sympathetic nervous system?</h2>

The peripheral nervous system and the central nervous system are the two primary divisions of the human nervous system, as shown in the image below.

Two additional parts make up the peripheral nervous system. Skeletal muscle movement that is voluntary is controlled by the somatic nervous system. The somatic nervous system is at action when you choose to bring your coffee cup to your lips; it is doing so by engaging the necessary muscles. The autonomic nervous system, which regulates functions outside of our conscious awareness, is the second part of the PNS.

The parasympathetic nervous system and the sympathetic nervous system are additional divisions of the autonomic nervous system (which you are interested in). They have negative consequences on one another, to put it very broadly. While the parasympathetic neural system largely works to calm the body, the sympathetic nervous system often stimulates the body. Although this is a streamlined perspective, it might be helpful to think about it this way.

The sympathetic branch of the autonomic nervous system speeds up heartbeat, slows down digestion, opens up airways in the lungs to allow for greater airflow, triggers the liver to release glucose, and relaxes the bladder. All of this wakes up the body and gets it ready to "fight."

The parasympathetic division, in contrast, slows the heart rate, tightens the bronchi in the lungs, and boosts blood flow to the digestive system. The phrase "relax and digest" has been used to describe it.

The parasympathetic nervous system's nerves originate from the brainstem and spinal cord, as shown in the diagram. The "ganglia" (collections of cell bodies) of the sympathetic nervous system, however, exist beyond the spinal cord.

It's interesting to note that whereas the sympathetic nervous system activates the body using both acetylcholine (ACh) and norepinephrine (NE), the parasympathetic nervous system solely needs ACh to affect organs.

The sympathetic and parasympathetic nerve systems are autonomic, which means we typically have minimal control over them.
