Answer:
Photosynthesis replace CO2 with O2 in the atmosphere. Plants prepare their food by this process.
The burning of hydrocarbon in the presence of O2 is called combustion.
CH4. + O2-----------> CO2. + H2O + Heat
Hydrocarbons undergo combustion.
Geology is yhe branch of science which deals with the study of earth. The person that studies geology is geologist.
Explanation:
Adding the inhibitor to the yeast cells in the petri dish would likely cause an increase oxygen usage by the cell.
HOW DO YEAST RESPIRE?
- Yeast are unicellular organisms that belong to the kingdom Fungi. Yeasts are capable of respiring anaerobically i.e. can respire without oxygen.
- Yeast can, however, respire both aerobically and anaerobically. Yeast undergoes an anaerobic respiration called FERMENTATION, which is used to produce ethanol (alcohol) from pyruvate (product of glycolysis).
- If a substance that inhibits the conversion of pyruvate to ethanol is added to yeast cells growing in a petri dish, the process of fermentation will be inhibited. Hence, the yeast cells will have to switch to aerobic respiration and make use of oxygen.
Therefore, adding the inhibitor to the yeast cells in the petri dish would likely cause an increase oxygen usage by the cell.
