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.

The top layers are the youngest and the farther you go down, the older they get. I’ll put it in exact order in a minute.
The answer is Vacuoles. After water enters this cell through the osmosis, it expands to absorb water and contract to release it.
It gets polluted from fertilizers or any spilled chemicals. And those chemicals get obsorbed into the ground. And the gravity pushes them deeper in the soil, till it reaches the underground water (or aquifer)
