In response to a state of shock, what mechanisms does the sympathetic nervous system utilize in the four distinct stages to help
svetlana [45]

Answer:

Increase in heart rate.

Increase in respiratory rate.

<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.

The codon AUG specifies the amino acid methionine. What would the tRNA anitcodon be that recognizes this codon?
NemiM [27]

Answer:

UAC

Explanation:

This example portrays that translation, which is the second process of protein synthesis, is about to occur. Translation cannot occur without a special type of RNA called tRNA or transfer RNA.

A tRNA contains a set of three nucleotides called ANTICODON. The tRNA matches an mRNA codon with the amino acid it encodes. The tRNA initially binds to the mRNA and reads the mRNA codon using its anticodon (which is complementary to the mRNA's codon). The actual reading is done by matching the base pairs through hydrogen bonding following the base pairing rule i.e. A-U, G-C. After reading the mRNA codon using its anticodon, it then carries the specific amino acid encoded by that codon it binds to, in order to add to the growing polypeptide chain.

For example, a codon AUG (start codon that signals beginning of translation) will be read by tRNA anticodon, UAC. Since the codon AUG codes for amino acid, Methionine. The tRNA then carries Methionine via its amino acid attachment site and adds to the polypeptide chain (future protein).

Two students set up the following apparatus in a lab: a pipette was filled with a mixture of yeast and apple juice and inverted
UkoKoshka [18]

Answer:

The most appropriate answer would be carbon dioxide and cellular respiration.

Yeast is a single-celled eukaryotic organism which is capable of doing anaerobic (fermentation) as well as aerobic respiration.

It uses cellular respiration (whether aerobic or anaerobic) for the production of energy, that is, adenosine triphosphate (ATP).

Cellular respiration refers to the set of chemical reactions which are involved in breaking down sugar or glucose to produce ATP. The carbon dioxide is produced as a byproduct.

Thus, yeast breakdown the sugar present in apple juice to produce ATP and carbon dioxide.

This carbon dioxide is released in the form of bubbles.
