<u>Answer:</u> The amount of drug that must be given is 102.3 grams

<u>Explanation:</u>

We are given:

Weight of the person = 150.0 lb

Converting this weight into kilograms, we use the conversion factor:

1 kg = 2.20 lb

So, 150.0lb\times (\frac{1kg}{2.20lb})=68.2kg

Applying unitary method:

For 1 kg of body weight, the correct dosage of the drug is 1.50 mg

So, for 68.2 kg of body weight, the correct dosage of the drug will be \frac{1.50mg}{1kg}\times 68.2kg=102.3mg

Hence, the amount of drug that must be given is 102.3 grams

Digiron [165]

Answer: Option D. "Heme"

Explanation:

Deoxyhemoglobin can be defined as a form of which has no oxygen binded to the hemoglobin.

When deoxyhemoglobin is replaced with oxyhemoglobin then the oxygen binds to the heme component of the hemoglobin protein in red blood cells.

Each heme group has iron atom that has the ability to bind to oxygen (02) molecule.

Four oxygen molecules bind to a single hemoglobin protein.

Hence, the correct answer is option D "Heme".

4) Considering the autonomic (visceral) nervous system identify which neurons are cholinergic and
Oxana [17]
<h2>Cholinergic and Adrenergic neurons</h2>

Explanation:

The autonomic nervous system (ANS) is a dual innervations system which innervates internal organs of the body through the sympathetic and parasympathetic nervous system (PNS). Depending upon the neurotransmitter and receptor used, the ANS fibers are classified as cholinergic or adrenergic neurons.

The preganglionic neurons of the sympathetic and the preganglionic and postganglionic neurons of the parasympathetic nervous system release the neurotransmitter acetylcholine (ACH) and hence are called cholinergic neurons.

The postganglionic neurons of the sympathetic nervous system releases catecholamine like norepinephrine(NE) and hence called as adrenergic neurons.

The cholinergic neurons store ACH in the synaptic terminals. They are myelinated to aid in faster neurotransmission. The ACH neurotransmitter released from preganglionic neurons activates the two receptors – nicotinic ACH and muscarinic receptors on the postganglionic neurons .

The postganglionic neurons releasing NE binds to the adrenergic receptors – Alpha 1 and 2, Beta 1, 2, and 3.
