Answer:
83) B wire
84) mixture of different hydrocarbon
85) to remove chlorophyll
86)halving of chromosome after gamete formation
87)accumulation of variation over several generation.
Answer:
83.)
A) A WIRE
REASON : THE RESISTANCE OF AN OBJECT IS THE VOLTAGE × CURRENT.
IF THE CURRENT IS DECREASING THAT MEANS THAT ITS RESISTANCE WILL BE HIGHER .
84.)
A) MIXTURE OF DIFFERENT HYDROCARBONS .

85.)
C) TO REMOVE CHLOROPHYLL
REASON :
THE WLCOHOL REMOVES THE CHLOROPHYLL MAKING IT READY FOR THE STARCH TEST .
86.)
C) DOUBLING OF THE CHROMOSOMES AFTER GAMETE FORMATION.
REASON :
THE CHOROMOSOMES MAKE AN EXACT COPY OF ITSELF AND JOIN THE ANOTHER OF THE CHROMOSOMES DURING GAMETE FORMATION .
87.)
B) ACCUMULATION OF VARIATIONS OVER SEVERAL GENERATIONS .
REASON :
NOT EVERY BIOLOGICAL PROCESS IS RELIABLE . THEREFORE DURING THE DNA COPYING THERE IS A SLIGHT VARIATION .
WHEN THIS VARIATIONS ACCUMULATE THEY MAKE A WHOLE NEW SPECIES.
