18. Which statement about photosynthesis is FALSE? a
Tilmy green pigment chlorophyll captures light
energy
b Oxygen is needed as a reactant to produce
glucose
The process converts light energy from the
csun into chemical energy in the bonds of
glucose.
d
Carbon dioxide is needed as a reactant to
produce glucose.

your query :

Which statement about photosynthesis is FALSE?

b. Oxygen is needed as a reactant to produce

glucose is the incorrect statement here

Explanation:

plants uses simple raw materials to prepare their food , which includes water ( H2O ) and Carbon dioxide ( CO2 ).

and traps sunlight by Green pigments known as chlorophyll and stores these energy in bonds of glucose molecules

so ,

after this reaction glucose and oxygen is formed as products

● hence we conclude that Oxygen is not needed as a reactant to produce glucose , oxygen is the bi product formed during photosynthesis.

Ans. : frostbite is when exposure to cold temperatures causes freezing to the skin or other tissues. it most commonly affects the hands, feet, and face. the longer areas are exposed to cold, typically the worse the frostbite. the water temperature used for rewarming a frostbitten part should be : (102 -105) f degrees.
