Explanation:
<em>A</em><em> </em><em>cell</em><em> </em><em>that </em><em>contains </em><em>organelles</em><em> </em><em>called</em><em> </em><em>Chloroplasts</em><em> </em><em>could</em><em> </em><em>be</em><em> </em><em>found</em><em> </em><em>in </em><em>plants</em><em>.</em><em> </em>
<em>Chloroplasts </em><em>are</em><em> organelles that conduct photosynthesis, where the</em><em> </em><em>chlorop</em><em>h</em><em>y</em><em>l</em><em>l</em><em>(</em><em>green</em><em> </em><em>pigments</em><em> </em><em>found</em><em> </em><em>in </em><em>plant)</em><em> </em><em>captures</em><em> the energy from sunlight, converts it, and stores it</em><em>.</em><em>A chloroplast is a type of organelle known as a plastid</em><em>.</em><em> </em><em> </em>
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.

If the Earths polar Ice melts the ocean levels will increase because of the increased amount of water. Some peninsulas and islands would decrease because they would sink from the risen water.
Answer:
True
Explanation:
<em>Aristotle initially thought that life arose spontaneously and he backed this up by showing that a lump of meat left uncovered in a glass jar spontaneously produced maggots.</em>
The spontaneous generation theory was later disproved by another scientist, Francesco Redi. He showed that a covered jar containing a lump of meat will not spontaneously produce maggots unless flies are allowed to perch and lay their eggs on the meat. The eggs of the flies give rise to the maggots and not the meat.
<u>It thus showed that new life does not arise spontaneously but rather through development and reproduction.</u>
