What is the greenhouse effect? How can humans reduce the level of greenhouse gases?
frozen [14]

Answer:

The greenhouse effect is the production of harmful gases that harm the atmosphere.

Humans can reduce the level of greenhouse gases by opting for alternate technologies or reducing their carbon emissions.

Explanation:

The greenhouse effect is the process of heating the earth's atmosphere by trapping the Sun's energy, thereby making the atmosphere hot. This natural process of trapping the heat is caused by numerous gases like methane, carbon dioxide, water vapor, and other gases. It's from this process that the atmosphere produces bad gases that damage the earth.

The reduction of the effect can be reduced by humans if they reduce their consumption of resources or energy. Moreover, shifting to alternate technologies that use lesser or no gasoline will also help in the reduction of greenhouse gases.

Preparing the body for the "fight-or-flight" response is the role of the ________.
den301095 [7]

How Neurons Work (1 of 3): Neuron Structure and Resting Potential (BioFlix tutorial)?
fiasKO [112]

 A neuron is nerve cells that transfer information within the body, chemically over short distances, using electrical signals over long ones.

   As it turns out, most resting neurons are permeable to Na+ and CL- as well as K+. K+ will try to drag the membrane potential toward its (positive) equilibrium potential, while NA+ try to drag the membrane potential to its negative equilibrium potential.

The real membrane potential will be between NA+ and K+ of equilibrium potential<span>. However, it will be closer to the equilibrium potential of the ion type with higher permeability.</span>
