<span>A cell can only grow so large in size because its
ability to exchange materials is affected by a growing surface-to-volume ratio.
Nature designed cells to be small in size because of the network of membranes
passing through it. If cells grow any bigger, membranes in it will not be able
to pass through its different parts and perform their purpose.
A cell is a network composed of many organelles (e.g. mitochondria, nucleus),
that communicate and work together to provide bodily functions. The cell is
small so that communication between organelles will be faster and much easier. When
cells are small they can be easily repaired when damaged and replicated when
needed.</span>
Answer:
Number 3 is “dark”
Explanation:
After the Industrail Revolution, there was a large growth in dark peppered moth population.
1. Evaporation is the escape of water molecules from their liquid phase to gas phase that go up into the atmosphere. Evaporation can occur anywhere where open liquid water is exposed to sunlight or any other source of energy. Transpiration, on the other hand, is the loss of water (by evaporation) from plants through the stomata. Evaporation and transpiration move water from the biosphere to the atmosphere.
2. Condensation is the return of water molecules from gaseous phase (vapor) back to liquid form. Precipitation, on the other hand, is the coming down of condensed water from the atmosphere to the earth (biosphere), which is a significant part of the water cycle.
3. Exchange pool is the pool from (or approximate amount) which water or other elements are shared (back and forth) between different spheres (such as biosphere, atmosphere, and hydrosphere) in a cycle. A reservoir on the other hand is analogous to a ‘container’ that holds large masses of water or other elements such as a lake and the atmosphere.
4. The answer is No. because, today’s waters, due to increased pollution from industrialization that spews a lot of pullutans into the atmphere, ae contamiated. The water that precipitates is tainted by gases such as sulphuric dioxide tha makes it acidic. The water also gets polluted by other pollutants in the atmpshre and biosphere and hence become a health risk to animals and humans that drink it.
