which one of the following processes does not occur to excess neurotransmitters in the synapse

Answers

This question is incomplete because the options are not given; here is the complete question:

Which one of the following processes does not occur to excess neurotransmitters in the synapse?

A. Break down or digested into inactive fragments.

B. Collection by scavenger vesicles left over from the neurotransmitter release.

C. Drifting away from the synapse via diffusion.

D. Reuptake within the pre-synaptic neuron.

The answer to this question is B. Collection by scavenger vesicles left over from the neurotransmitter release.

Explanation:

The word synapse refers to the neurological structure that allows the transmission of signals or information between neurons. This process occurs through neurotransmitters, which are the molecules or substances with the messages.

Moreover, in this process, there can be in some cases excess. In this situation, the body reacts to this excess by degrading or breaking down the extra neurotransmitters, eliminating it through diffusion, or even reabsorbing it (reuptake). In this context, all are processes that occur due to excess neurotransmitters except collection by scavenger vesicles because in most cases neurotransmitters are simply absorbed or eliminated but there are not specialized scavenger vesicles that collect them.

By what factor (how much) does the milli- unit differ from the centi- unit?
earth science

Answers

Answer:

By a factor of 0.1.

Explanation:

Hello,

In this case, since the milli- unit has a factor 0.001 and the centi- unit a factor of 0.01 we can apply the following division in order to compute by what factor they actually differ from:

[tex]\frac{milli}{centi}= \frac{0.001}{0.01} =0.1[/tex]

It means that the milli- unit differ from the centi- unit by a factor of 0.1. Conversely, the centi- unit differ from the milli- unit by a factor of 10:

[tex]\frac{centi}{milli}= \frac{0.01}{0.001} =10[/tex]

Answers

Answer:

Hope it helps.

Sue has Parkinson's disease. She takes medication that increases the level of dopamine in her brain.

What is Parkinson's disease?

It is a neurodegenerative disorder characterized by a loss of dopamine-producing cells in the brain, particularly in an area called the substantia nigra.

Dopamine is a neurotransmitter that plays a crucial role in coordinating movement and regulating various brain functions.

In Parkinson's disease, dopamine deficiency leads to impaired communication between brain cells, resulting in the motor symptoms associated with the condition, such as tremors, stiffness, and difficulty with movement and coordination.

To address this dopamine deficiency, medications known as dopamine agonists or levodopa are commonly prescribed.

These medications work by increasing the levels of dopamine in the brain, compensating for the deficit caused by the disease.

Thus, Sue takes medications that increase the level of Dopamine.

Answers

Both dopamine and serotonin are involved in your sleep-wake cycle. Dopamine can inhibit norepinephrine, causing you to feel more alert. Serotonin is involved in wakefulness, sleep onset, and preventing REM sleep. It's also required to produce melatonin.
dopamine brings feelings of pleasure and a happiness boost while serotonin is more of a stabilizer than a booster

dopamine primarily controls movement, and serotonin contributes to sleep and digestion

Analyze the map below and answer the question that follows Solve for x (see image) 01.04 WorksheetThe Reefs By Marcella MorrisShe clutched her lab work to her side and walked briskly towards school. The snow fell in typical New York flurries, and the ground was still icy from last nights freeze. Careful not to slip, she climbed the steps and crossed the campus toward the science building."What am I doing?" she murmured. Sophies worst habit was talking to herself in public. "I have been warned.""You are just a high-school kid, Sophie," they warned. "What makes you think you are capable of solving this crucial environmental issue? Stop wasting your time." The professors would not give her laboratory time to complete research nor would they share their expertise with her.But, she could not stop.After a snorkeling trip she took with her aunt to the coral reefs, she felt that something had shifted inside her. The snorkeling guide made one fact very clear: these colonies of tiny organisms would not last. In fact, wed be lucky if they lasted five more years. She cared about the safety of these coral reefs more than she has cared about anything for a long, long time. She had to do something for the fragile, endangered habitat with its fish, mollusks, worms, crustaceans, and many more.She used her money to create a lab at her aunts house. She worked tirelessly--endlessly--sleeping only when she had to."Its what Mom and Dad would have done," she thought.Sophie's best friend, Sam, would hang out with her every day--eating pizza, fries, and whatever else he could get his hands on, keeping her company with his humor while she worked on her experiments. And now, she has a biological solution in her hands.She hesitated at the door to the labs. Nervously, she shifted her lab report from one hand to the other."I know that I have an innovative approach to solving the coral reef issue and I know I can help," she said to no one. The image of being ridiculed by these professors delayed her entry. She stood outside the door, wanting to run back--wanting to hide--glued to the icy spot."Hey, Sophie!" She turned at the unexpected sound of Sams voice."Ive beentrying to catch up with you," he panted, out of breath. "Lets go in andshow themwhat youve got."Sophie tilted her head, smiled at Sam, and opened the door. She walked confidently to the front, laid out her research on the podium, and began her presentation. When her presentation ended, it was to the enthusiastic sound of the scientists applause.
