Which of these is the correctly balanced equation for photosynthesis?
C6H12O6 + 6O2 → 6CO2 + 6H2O
C6H12O6 + 6O2 → 6CO2 + 6H2O
C6H12O6 + 6CO2 → 6O2 + 6H2O
CO2 + H2O → CH2O + O2
6CO2 + 6H2O-->C6H12O6 + 6O2
Which useful energy transfer or conversion happens overall in photosynthesis?
Chemical → light
Light → heat
Light → chemical
Chemical → heat
In the activity for CO2 is essential for the photosynthesis process.
Role of KOH is to (a) and Vaseline is to (b).
(a)Absorbs O2 (b)Maintains constant temperature
(a)Absorbs CO2 (b)Maintains constant temperature
(a)Maintains air tight condition (b)Maintains constant temperature
(a)Absorbs CO2 (b)Maintains air tight condition
How saprophytes and parasites different from each other,even-though digestion of nutrient is not done in any of these bodies?
saprophytes absorbs food from host and parasites from dead host
saprophytes absorbs food from dead host and parasites from living host
saprophytes don't digest food but absorbs food from dead host and parasites from living host
saprophytes digest food outside the body and absorbs digested food from dead host and parasites from living host
saprophytes digest food outside the body and absorbs digested food from dead host and parasites don't have enzymes and don't do digestion ,simply absorbs digested food from living host.
