Autonomic nervous system reactivity in humans appears to be inherited.

<h2>Answer:</h2>

The correct option is inherited. Autonomic nervous system reactivity in humans appears to be _<u>Inherited</u>___.

<h3>Explanation:</h3>

There are two types of nervous systems:

  • Sympathetic nervous system
  • Autonomic nervous system.

Sympathetic nervous system prepares the body for the emergency conditions an somehow it is under the conscious control while autonomic nervous system controls the body unconscious like breathing and heart beat rates.

So the autonomic nervous system is inherited not learned.

If a paper clip floats on water, what would happen to it if you if you drop soap near it?
Mars2501 [29]

Nothing really big... It floats because of density not surface tension.

But You can try and discover what will happen.  :)

(   P.S if you'll drop soapstone it will probably create nice waves...  )

____________ is the process by which inhibitory transmitters cause the inside of the neuron to become more negative.
lidiya [134]

Answer:

Hyperpolarization

Explanation:

At the synapse, neurotransmitters bind to neurotransmitter receptors in the postsynaptic neuron’s plasma membrane. This results in the opening of the ions channels and the flow of specific ions to change the voltage across the membrane. An inhibitory neurotransmitter inhibits the firing of the action potential by making the inside of the membrane more negative. It is called hyperpolarization (inhibition).

It may occur when the neurotransmitter opens the Cl– or K+ channels to allow the movement of chloride ions into the cell while permitting the outward movement of potassium ions to make the inside of the cell more negative.

Genes A and B are 10 map units apart and genes B and C are 20 map units apart, with gene B located between genes A and C. What w
Marizza181 [45]

Answer:

2% of the progeny will be double crossovers for the trihybrid test cross

Explanation:  

By knowing the positions of genes, we can estimate the distances in MU between them per region.

  • Genes A and B are 10 map units apart (Region I)
  • Genes B and C are 20 map units apart (Region II)
  • Genes A and C are 30 map units apart

----A-------10MU--------B-------------20MU-------------C---

             Region I                      Region II  

We can estimate the recombination frequencies by dividing each distance by 100.

• recombination frequency of A-B region = 10MU / 100 = 0.10

• recombination frequency of B-C region = 20MU / 100 = 0.20

Now that we know the recombination frequencies in each region, we can calculate the expected double recombinant frequency, EDRF, like this:

EDRF = recombination frequency in region I x recombination frequency in region II.

EDRF = 0.10 x 0.20 = 0.02        

2% of the progeny will be double crossovers for the trihybrid test cross
