Your roommate, who has not studied climate, says, "I thought the greenhouse effect was a bad thing. Isn't it what's causing glob
Masja [62]

Answer:

b) and c)

Explanation:

Greenhouse gases are gases found in the atmosphere that absorb infrared radiation and trap the sun’s heat, thereby producing an effect known as <em>greenhouse effect.</em> By this natural way, the earth is able to be kept warm at an optimal temperature, to make it habitable for humans and other organisms. These gases referred to as <em>greenhouse gases</em> include, carbon dioxide, methane, water vapour and other trace gases found in the atmosphere.  Greenhouse gases could be likened to the glass in a greenhouse that helps in trapping heat to keep the greenhouse warm at optimal temperature necessary for plant growth and development.

Without this natural greenhouse effect caused by greenhouse gases, life on earth would be almost impossible as the earth would almost be covered with ice below 0 degrees Fahrenheit.

The increased level of greenhouse gases we now find in the earth’s atmosphere is responsible for the additional warming of the earth’s surface, causing an enhanced greenhouse effect which results in global warming.

Statement a) cannot be used as an explanation because it is false. Greenhouse effect makes the earth habitable.

Statement d) cannot be used as an explanation because carbon dioxide is not the only greenhouse gas that matters. Water vapour, CFC and methane also have impacts.

<em>Statement b) and c) are the best statements to use in explaining the true nature of greenhouse effect. </em>

Communication between neurons occurs from contact between the two neurons. when the intensity of the action potential increases
Kitty [74]

Answer:

The correct answer is - when action potentials trigger the release of neurotransmitters.

Explanation:

Communication between neurons takes place by signaling that can be either chemical signaling or electrical signals. Communication between neurons occurs at very small gaps known as synapses.

These synapses have two specialized cells that help two neurons communicate by one to another to allow for chemical transmission. The chemical that isreleased due to the stimulation of the action potential in order to communicate the neurons are known as neurotransmitters that allow for transmission.

Lisa had 20 grams of water. She poured out 15 grams. Which of the following physical properties of the water changes? (4 points)
Black_prince [1.1K]

Answer:

Volume

Explanation:

The boiling point and density of water never changes, no matter how much you add

So the answer CAN'T be Boiling point or Density

Electrical Conductivity changes <em>only when the number of ions in a solution changes</em>

So it CAN'T be Electrical Conductivity

It has to be VOLUME because volume is the only physical property that changes when you add or take away liquid from a liquidous mixture
