What are four characteristics of a good extraction solvent?
ella [17]

A good extraction solvent should have a strong solubilizing capability for the compound of interest, it should be immiscible or only weakly misciblewith the matrix solvent ( the first solution or mixture containing the compound from its natural source, e.g., water/ether. water/ chloroform, etc. If possible the extraction solvent should be non-flammable, non-toxic or of low toxicity, reasonably volatile, and of low eco-impact. Inexpensive and available, of high purity , and shelf stable. If one is determining the compound of interest by UV/Vis spectrophotometry or fluorescence, the solvent should have extremely low absobance or emission at the wavelength of analysis

• high solubility for the solute and low solubility for the carrier liquid.

• density difference vs. the carrier liquid greater than 150 kg/m. ...

• mid-level interfacial tension (5–30 dyne/cm)

• high resistance to thermal degradation.

Kaylis [27]

Answer:

No.

Explanation:

No, Surtsey island and Iceland newest volcanic island will not become an atoll because these islands have no underground volcanoes. The atolls are only occur when the volcanoes are present underwater and we know that these volcanoes are present on the lands not in the water so there is no possibility of having atolls in these Surtsey and Iceland volcanic islands

In a common reflex arc, after a sensory nerve signal is processed by interneurons in the integration center, where does the sign
kobusy [5.1K]

In a reflex arc, after a sensory nerve signal is processed by interneurons in the integration center, the signal goes to the motor neuron. The answer is motor neurons.

<h3>What is the reflex arc?</h3>

The reflex arc refers to the sequence of events since the body receives an external stimulus until it reacts.

In general terms,

1) A stimulus of varying nature reaches the body.

2) The peripheric nervous system -PNS- receives the stimulus and sends this information to the central nervous system -CNS-.

3) The CNS processes the information and sends another signal as a response to the stimulus.

Five elements compose the reflex arc, which are receptors, three types of neurons, and effectors.

The neurons involved in the mechanism are:

• Afferent or sensorial neurons

• Interneurons

• Efferent or motor neurons

Mode of Action:

  • <u>Ascending branch</u>

The stimulus reaches the body and is received by the specialized sensory receptors.

Afferent neurons, placed in the dermis and epidermis, receive this information from receptors, react and send it to the central nervous system as nerve impulses.

  • <u>Descending branch</u>

Interneurons in the CNS, process the information and send a motor response.  

Efferent neurons carry the response from the CNS to the effector organs, which might be either a muscle or a gland.

Finally, the target tissue responds to the stimulus as a contraction -muscle-,or as hormones release -gland-.

A motor neuron is formed by a cellular body, dendrites (cytoplasmic extensions that receive stimuli from other cells), and a long axon that is capable of conducting the electrochemical signals.

The axon brunches out into several extensions when it approaches the muscle.

At the end of each brunch, the axon is inserted in the muscle fiber surface, composing neuromuscular join.

This is the last part of the NS involved in the process before the muscle contracts.

After a sensory nerve signal is processed by interneurons in the integration center, the signal goes to the motor neuron, and from there to the effector.  

The corrct answer is motorneuron.

The mass of an object is always
iVinArrow [24]

Answer:

equal to the sum of its parts.

Explanation:

Required

Which option answers the question?

The mass of an object is the total amount of matter in that object. When the term total amount in describing a concept, it means the summation of all its constituents.

In fact, that is the reason why the mass of an object is always constant because it is independent on gravity.

Take for instance, a brick.

Every part of the brick contribute to the mass of that brick and whenever the brick loses some of its part, either through wear and tear or any other means, the brick loses the mass of the lost part.

Hence, from the list of given options; option B is correct.
