Is hot cocoa a homogeneous or heterogeneous mixture?

Hot cocoa is a homogeneous mixture. Homogeneous mixtures have uniform composition and properties throughout and are known as solutions. For e.g, when sugar/salt is dissolved in water it forms a solution in which the sugar/salt and water are uniformly mixed (the sugar is dissolved uniformly in water). e.g.air Heterogenous mixtures are those which aren't uniform in composition and properties throughout e.g. granite which consists of quartz, feldspar and mica and you can identify each of the substances separately in the mixture.

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.

answer: cellular respiration takes in food and uses it to create atp, a chemical which the cell uses for energy. usually, this process uses oxygen, and is called aerobic respiration. it has four stages known as glycolysis, link reaction, the krebs cycle, and the electron transport chain.
