<span>A cell is the most basic form of
life. It is what most of the organisms are made off. For the organism to
function, the cell must also function. It has organelles too that helps
functions what the microorganisms need. A leaf cell contains chloroplasts that
animal cells and animal cells do not have.
The chloroplast is where the photosynthesis happens. It needs sunlight
for the process of photosynthesis. Notice that the leaf has a broader surface
area to enable them to be exposed to the sun.</span>
Answer:
There is a term "atmospheric circulation". It is when the air throughout the globe moves around. When the sun heats air near the equator more, and less at the poles. So the equator is warmer. The warm air near the equator moves either towards the south or the north, toward the poles. The warm air also rises up, and the cold air sinks. This is convection, but at a global scale. THis is also the cause of wind.
<span>b The growth of teeth in chickens supports the hypothesis of a common ancestor between birds and reptiles. This is a generally accepted hypothesis, and i'd go with this answer. Obviously we can't say whether chickens will have teeth with certainty, the chickens with teeth are clearly still chickens, and a baby croc isn't hatching out of a chicken egg any time soon.

Answer:
Charles Robert Darwin (1809-1882) transformed the way we understand the natural world with ideas that, in his day, were nothing short of revolutionary. He and his fellow pioneers in the field of biology gave us insight into the fantastic diversity of life on Earth and its origins, including our own as a species.
