The correct answer is fight or flight.
The fight or flight response also called acute stress response, is a physiological response to a perceived attack, threat or in general any stressful event. This reaction consists the first stage of the general adaptation syndrome, which is the mechanism that regulates the response to stressful situations.

This response consists of an activation of the autonomic nervous system and a cascade of hormones, including catecholamines, cortisol, estrogen, testosterone, and dopamine. This hormonal cascade results in many physiological changes which prepare the body for action.

What happens to a cell when immersed in a beaker of distilled water?
stich3 [128]
You haven't specified if which type of cell you are referring to. There are many types of cells and each cell would have different reactions when immersed in a beaker of distilled water. So let us take for example, the red blood cell. A distilled water is hypotonic compared to the solution contained within the cells' membranes. Therefore, t<span>he distilled water will diffuse into the red blood cells and cause them to burst. Hope this answers the question.</span>

Answer:

The geosphere or geosphere is the internal and solid part of the Earth that is composed of three concentric layers called crust, mantle and nucleus. Without the geosphere, human beings cannot live on the planet, since there is no solid ground. In the Earth's geosphere are rocks, minerals, magma, sand and mountains.

This layer interacts with the other layers of the earth system, including the atmosphere, hydrosphere and biosphere, and is in a state of constant motion; Sedimentary, igneous and metamorphic rocks within the Earth's geosphere undergo continuous recycling.

It is said that the Earth formed about 4.6 billion years ago from the collision of meteoric debris that created the solar system. Due to the constant collisions during its formation, the initial temperature of the planet was extremely high; It was all molten matter.

But during the next phase of Earth's formation there was a cooling, and with it, the differentiation of the Earth's layers. Dense materials sank in the center, forming a core rich in iron and nickel. The lighter magma rose to the surface, forming the thickest layer of the Earth called the mantle.

Eventually, the outermost magma cooled to form the thin layer we call Earth's crust.

Multiply 5730 years by 2 since two half-lives have gone by for carbon.

<u>Explanation</u>:

The half-life of a radioactive isotope depicts the measure of time that it takes half of the isotope in an example decay. On account of radiocarbon dating, the half-existence of carbon 14 is 5,730 years  

The half-life of carbon-14 is 5730 years.  

In this manner, after  

1 half-life there is 50 % = 1/2 of the first amount left.  

2 half-lives there is 25 % = 1/4 of the first amount left.  

25% is two half-lives.  

Every 50% of life requires 5730 years.  

So two half-lives require 2 × 5730
