Axons from mPFC neurons synapse onto intercalated cells in the amygdala that contain the neurotransmitter __________.

1 answer:

8 0

The medial pre Frontal Cortex neurons synapting with the intercalated cells of Amygdala contains <u>GABA</u> as the neurotransmitter.

Option a

<u>Explanation:</u>

The Amygdala has two types of nerve cells getting attached with it primarily. They are the fibres from the mPFC or medial pre Frontal Cortex and the vIPAG or ventrolateral periaqueductal grey. These neurons do have different functions on the whole body.

The fibres from the mPFC do have emotional function on the human body whereas the fibres of vIPAG do have an effect on the muscle tone . And it's seen that both the nerve fibres that are getting attached with the intercalated cells of Amygdala do secrete GABA and are inhibitory GAB Anergic in nature.

The rate at which the concentration of a drug in the bloodstream decreases is proportional to the concentration at any time t. I

Westkost [7]

Answer:

$C(t) = C_oe^{-kt}$

Explanation:

From the given information:

At any given time (t), let c(t) represent the concentration of the drug present in bloodstream.

Deriving the equation:

$\dfrac{dC}{dt}$ decrease proportionally to Concentration C

i.e

$\dfrac{dc}{dt} \alpha - C$

$\dfrac{dc}{dt} = -k C$

$\dfrac{dc}{c} = -k dt$

$\int \dfrac{dc}{c} = -k \int dt$

㏑(C) = -kt + λ

where,

λ is the integration constant.

Integrating at t = 0, concentration of blood = Co g/mL

C(0) = Co

㏑(C₀) = 0 + λ

λ = ㏑(C₀)

From ㏑(C) = -kt + λ

㏑(C) = -kt + ㏑C₀

㏑(C) - ㏑C₀ = -kt

$\dfrac{C}{C_o} = e^{-kt}$

$C(t) = C_oe^{-kt}$

∴

The concentration of drug in blood at any time t is:

$C(t) = C_oe^{-kt}$

What is the significance of a recombinant plasmid?

drek231 [11]

Answer:

recombinant DNA

A strand of DNA formed by splicing DNA from 2 different organisms is called recombinant DNA

Explanation:

Using the techniques of recombinant DNA technology, certain enzymes known as restriction enzymes capable of cleaving double stranded DNA in the plasmid of bacteria genomes (other organisms like eukaryotes can also be used) are used to obtain specific sequences of DNA bearing desirable traits in the both organisms.

Once the two DNA fragments have been obtained, another enzyme known as DNA ligase is used to seal the point of splicing, thereby constructing a single DNA from the two organisms.

This single DNA is known as Recombinant DNA

Why is laser lights so important for us? 6-7 sentences

andreev551 [17]

Lasers can be used in surgical operation such as eye surgery because they are so precise.
The laser can be used in microscopy to produce very clear visuals and study very minute substances.
Lasers can be used in navigation also due to their precision hence reducing accidents
We use lasers to scan barcodes in supermarkets
Powerful lasers can also be used or security purpose for shooting down flying objects that can cause damage to humanity, such as missile and asteroids.
A phenomenon called laser cooling has been used to trap an atom and assist in its study so scientists are able to understand the universe.

State the law of magnetism

Mrrafil [7]

Law of Magnetism. The most basic law of magnetism is that like poles repel one another and unlike poles attract each other; this can easily be seen by attempting to place like poles of two magnets together.
