Nicotine from cigarette smoke acts as a ligand and associates with the acetylcholine receptor on specific cells in the nervous s

ystem. Nicotine eventually produces feelings of pleasure and well-being. The listed statements are descriptions of the events that happen in the cellular response to nicotine. Place the events in the correct order to describe the steps in the signaling pathway.
A) The acetylcholine receptor is an ion channel, and when a ligand binds, the ion channel opens.
B) An influx of ions carries the signal to the reward areas of the brain.
C) Nicotine binds to the transmembrane protein that normally binds the neurotransmitter acetylcholine.
D) The signal causes release of dopamine in the brain, which causes good feelings.
E) Nicotine is quickly eliminated from the body (causing cravings for more cigarettes to produce good feelings).

Answer:

The correct order of events is:

C) Nicotine binds to the transmembrane protein that normally binds the neurotransmitter acetylcholine.

A) The acetylcholine receptor is an ion channel, and when a ligand binds, the ion channel opens.

B) An influx of ions carries the signal to the reward areas of the brain.

D) The signal causes release of dopamine in the brain, which causes good feelings.

E) Nicotine is quickly eliminated from the body (causing cravings for more cigarettes to produce good feelings).

Explanation:

Nicotine acts on acetyl cholinergic receptors that are located in membranes of the midbrain neurons. Nicotine can activate those receptors or block them more efficiently than acetylcholine.   Stimulation of nicotinic receptors leads to an increase in ions flow that reaches the brain and causes dopamine release in the nucleus accumbens through axonal prolongations of the dopaminergic pathway. This response is responsible for the smoker´s recompense sensation.

The dopaminergic pathway is the most important way in the process of nicotine dependence and addiction to the drug.

“Coronavirus Is Mutating”, what could be the reason for it? (Research) and tell your answer in your own simple words
Aleonysh [2.5K]

Answer:

Explanation:

Coronavirus is mutating because as more people are getting the virus, that gives that virus a change to mutate and form a different strand. When a virus hijacks a person cells, it causes that cell to start producing the DNA of the virus, but because human cells where not made to produce the DNA of a virus, mistakes happen, thus slightly changing the DNA of the virus which can then cause a new strand of the virus to appear.

Which of the following statements is an accurate explanation of a negative feedback mechanism used by animals to regulate body temperature? C) A ground squirrel's hypothalamus detects changes in environmental temperatures and responds by activating or suppressing metabolic heat production

Explanation:

The temperature-regulating center of vertebrate animals is located in the hypothalamus.

Doss [256]

Answer: The correct option is B.

Will genetically modified crops increase profit for farmers?

Explanation:

This is because genetically modified crops are produced to achieve a particular advantage. Genetically modified crops are produced with some traits that are beneficial to Agriculture. Farmers choose genetically modified crops in order to increase yield, and produced crops that are resistant to certain diseases. These genetically modified crops are produced because of the traits that increase crop yield when farmers plant them it will increase the profit of farmers.

<u>Answer:</u>

<em>Six centromeres are observed in a prophase cell from an insect, there are </em><u><em>20 pairs of chromosomes present</em></u><em>. </em>

<u>Explanation:</u>

<em>Centromeres is defined as the part of the DNA</em> which are held responsible for the directional changing of chromosomes.

And these chromosome gets divided into <em>2 daughter cells while undergoing the process of mitosis and meiosis. </em>
