lakkis [162]
<span>C02 + H20 -> C6H12O6 + 02
theres no co2</span><span>Sugar is made through photosynthesis by a chemical reaction within the plant’s cell.  Photosynthesis takes place in the chloroplast of a cell.  Light is absorbed into the cell by chlorophyll which is located in the chloroplast (an organelle in a plant cell.).  The chemical reaction that produces sugar is powered by the sun’s energy.  Carbon Dioxide, CO2, is absorbed by the plant through the stomata (small openings on the underside of the plants leaves) and water, H20, which is absorbed through the root hairs are combined together in a chemical reaction, which produces glucose, or the sugar that plants use for energy.  The chemical formula for the process is 6CO2 + 6H2O (+ light energy) =C6H12O6 + 6O2.</span>

I have no clue how to answer this
marta [7]

I believe this question is trying to get you to realize the difference between acquired traits(one you get through doing something during life) and heritable traits(ones from Mom/Dad). For example, I really wish I was 6 foot 4... but the height trait comes genetically from your parents since it is coded in my DNA how tall I will be, therefore this trait must be passed down genetically and somewhere down the evolutionary tree the humans in the region which my family comes from was better off being short. An example that comes from acquired traits could be muscularity... my parents are both not very muscular but throughout my lifetime I enjoy working out and have become much more muscular, no matter how much your parents or grandparents lift weights YOU won't change so that change must be acquired through aging during your lifetime. Now the amount of muscle your body can put on is a heritable thing but that is beside the point. Hope this helps :)
