Which coefficients balance this equation? _CH4 + _O2 -> _CO2 + _H2O A. 1, 1, 1, 1 B. 1, 1, 2, 1 C. 1, 2, 1, 2 D. 2, 1, 2, 1
ICE Princess25 [194]
C. 1,2,1,2
1 CH4+ 2 O2= 1 CO2+ 2 H20.
when balancing, you need to make sure that each side has the same number of each atom. The reason for this is to abide by the law of conservation of mass; essentially you can't have more or less than you put in the equation.
When you put the coefficients of C. into the equation you have a total of 2 carbon atoms on each side, 4 hydrogen atoms, and 4 oxygen atoms.
When a plant is using transpiration to cool off during the day, its stomates are __*open*__ and its water potential is __*higher*__ that of the soil. At night, the plant's water potential will be __*lower*__ that of the soil.
*__* are the answers
Hope it helped!
1) Colonial organisms require large areas with resources to sustain the entire colony, just as colonial people do. They are unable to grow in places that are sufficient to sustain a small number of organisms and if their population becomes to large, the colony collapses on itself. This is all visible in people as well.
2) Colonial organisms have greater safety due to their large numbers; however, unlike individual organisms, they are unable to sustain themselves with a smaller number of resources and migrating from one area to another is also more difficult for them.
3) A multicellular organism is more mobile and able to perform more functions in a better manner; however, this also leads to greater energy requirements than that of a single celled organism.<span />
