Answer: Anesthesia

Explanation:

Anesthesia was used in 95% of Civil War surgeries. Sulfuric ether had been discovered in Europe in the 1830's and was first used as an anesthetic by William Morton in 1846. After a successful public demonstration it became widely used in surgery.

Sergio [31]

Answer:

If an inhibitory synapse fires at the same time and at the same distance from the initial segment as an excitatory synapse of the same intensity there will be no changes in the potential in the firing zone.

Explanation:

Under normal conditions, the transmembrane potential depends on the ionic charges present in the intracellular and extracellular spaces. The extracellular space load is usually positive and in the cytoplasm is negative.

  • <u>Depolarization</u> occurs by opening ion channels that allow sodium to enter the cell, making the intracellular space more positive.
  • An opening of potassium channels releases this ion to the extracellular space, leading to <u>hyperpolarization</u>.

An excitatory synapse is one capable of depolarizing a cell and boosting the production of action potential, provided it is capable of reaching the threshold of said potential.

On the other hand, an inhibitory synapse is able to hyperpolarize the cell membrane and prevent an action potential from originating, so that they can inhibit the action of an excitatory synapse.

The interaction between two synapses, one excitatory and one inhibitory, -called synapse summation- will depend on the strength that each of them possesses. In this case, the intensity of both synapses being the same, there will be no changes in the membrane potential in the firing zone.

A) planets with long orbits

*all planets in groups 1 and 2 revolve around the sun!
*planets in groups 1 and 2 have moons
*group 2 have the fastest rotations

Our solar system is divided into two sections, the first section being the inner planets consisting of Mercury, Venus, Earth, and Mars.
The second section consists of Jupiter, Saturn, Uranus, Neptune, and Pluto.

The main differences between the two sections are distance from the sun. With the exception of Pluto, All outer planets are massive in comparison to the inner planets.

If two parents have an autosomal dominant trait, what can you say about their children?
balu736 [363]

Answer:

If a child has an autosomal dominant trait, then at least one parent has the autosomal dominant trait. If both parents have an autosomal dominant trait, then all of their children will have that trait. If both parents have an autosomal recessive trait, then all of their children will have that trait.

What does cell specialization in multicellular organisms allow cells to do?
Anna71 [15]

Answer:

Allows to give rise to different organs.

Explanation:

Since all the cells in our body have developed from a single cell, "the egg or ovum fertilized by a sperm", all of them are identical, that is, they have exactly the same instructions, but depending on the organ they form part, they will use only part of the information or another. This is known as cell specialization.

Thus, the nerve cells possess the information necessary to form hair and the cells that form hair possess the information necessary to form nerves. However, once specialized, nerve cells will form nerve tissue and hair cells will form hair.

In this way, being different recipes, the cells give rise to different organs.
