<span>jeremy's SUBSTANCIA NIGRA  is producing less DOPAMINE than what it needs to.

Substancia nigra is a "black substance" located in the midbrain. When there is the death of dopaminergic neurons in the substantia nigra, the quantity of dopamine decreases, causing Parkinson symptoms. With time passing, the fewer neurons Jeramy will have and those symptoms will become more severe, that is the reason why is smoking more. The nicotine from cigarettes help modulate dopamine transmission and so, to reduce some symptoms.</span>

When a neuron responds to a particular neurotransmitter by opening gated ion channels, the neurotransmitter is serving as which
GrogVix [38]

The question is incomplete as it does not have the options which are:

A) relay molecule

B) transducer

C) signal molecule

D) response molecule

Answer:

C) signal molecule

Explanation:

The transmission of signals in the neurons takes place in the form of electrical energy and chemical energy. The signals get transmitted in the form of electrical signals inside the neurons but when the signals have to be passed on to the next neuron on the pathway then the electrical signals get converted into the chemical signals.

The electrical signals cause the release of the chemical signals molecules called neurotransmitter from the synaptic vesicles in the presynaptic neuron and also opens the gated ion channels at the terminal. The neurotransmitter thus acts as a signal molecule in the transmission of a signal through neurons.

Thus,  C) signal molecule  is the correct answer.

Bone marrow transplant taken from a donor and infused through the central vein is coded to what icd-10-pcs code
slava [35]
The ICD-10-PCS code is 30240G4.

Firstly, select "Administration" (section 3) because the procedure is the administration of bone marrow to the patient. Secondly, select "Circulatory" (section 30) because it is being administered in a vein (circulatory system). Third, select "Transfusion" (section 302) because it is being done a transfusion of bone marrow. Then select "Central Vein" (section 3024) because that's the place of administration in the circulatory system. Lastly, go to "Bone Marrow" (section 30240G) as that is what's being transfused and then choose "Transfusion of Allogeneic Unspecified Bone Marrow into Central Vein, Open Approach" (<span>30240G4) because it is not specified what type of transfusion it is.</span>

The major difference between starch, glycogen, and cellulose and their adjacent glucose subunits is the ________.
sveta [45]

Answer:

<u>Starch</u> is the storage form of glucose (energy) in plants and the glucose molecules are linked by alpha 1,4 glycosidic linkage.

<u>Cellulose </u>is a structural component of the plant cell wall and glucose molecules are linked by beta 1,4 glycosidic linkage.

<u>Glycogen</u> is the storage form of glucose (energy) in animals and glucose molecules are linked by alpha 1,6 glycosidic linkage.

Explanation:

All of these sugars are polysaccaride sugars containing large number of glucose subunits.

Starch is a polysaccharide extracted from agricultural raw materials. It contains amylose and amylopectin. Amylose is an un-branched chain polymer of D-glucose units while amylopectin is a branched chain polymer of D-glucose units.

Glycogen is the storage form of glucose in animals, It is stored in muscles and liver and it is a branched polysaccaride.

Cellulose is the storage form of glucose in plants and leaves.

Since broth cultures of bacteria can reach high numbers of cells quickly, a series of answer experiments (one word) is required
nexus9112 [7]

The answer is Dilutions

Bacterial culture is one of the laboratory examination that could be used to determine if a specimen contain bacteria. But it will hard to count the colony if the bacteria count is too high.

That is why the specimen of the culture need to be diluted to reduce the bacteria count of the specimen, so the result will be easier to count. The unit used would be colony forming unit(CFU) per milliliter.
