Answer:
I believe I have had this question this before. The correct answer should be rr, BB.
<span><span>Large nameplate capacity per plant, typically around 1 GW.
</span><span>Typically 90% capacity factor, maximizing output from the nameplate capacity.
</span><span>Small fuel transportation volumes as the fissionable material just isn't that big or heavy compared to equivalent fossil fuel BTU sources.
</span><span>Low CO2 per MWH on a full life cycle basis. ~12 grams which is only slightly more than wind / solar.
This is a reason nuclear is a much better source for one of the major pressing problems of today than fossil fuels: global warming.</span>No particulate matter pollution.No sulfur dioxide or other chemical pollution.<span>Low fatalities per TWH.
Nuclear is higher than renewables according to current statistics, but much, much lower than fossil fuel generation.</span></span>
Nuclear power generates lots of clean, stable energy.
If the temp.rises then it will lead to excessive evaporation in hydrosphere, on lithosphere it willl cause extreme hot conditions and with the scarcity of water the animals, birds will die and also plants will be affected.Hydrosphere and lithosphere are included in biosphere so it willl altogether effect biosphere...
the first one is renewable and the second is it will destroy ecosystems
Answer:
Option 4 - Calcium
Explanation:
The <em>divalent cation </em>called <em>calcium</em> is needed to provide additional support to the bone matrix.
Calcium is considered one of the most <em>important components</em> in bone development. It helps in the formation as well as maintenance of bone. During the modeling and remodeling process of bones, calcium facilitates the formation of <em>semi-hard new tissues</em> which leads to the formation of new bone which is very hard.
Due to this reason, calcium is needed to create extra bone matrix support.
