Cells are limited in size by their surface area and volume ratio which means that when cells get so large, there is a limit that they can no longer obtain enough oxygen and nutrients. This process is involved in cell growth.
The city of Los Angeles released 96 million "shade balls" into the Los Angeles Reservoir. These will serve to shield the water from the sun's heat in order to reduce evaporation and prevent algal and bacterial growth so no toxic substances are produced in the water. The balls reduce evaporation by 85%-90% so will save a lot of water yearly.
I wanna say D.
Sorry if I’m wrong:(
