Answer:
100 000
Explanation:
The average length of a base pair (bp) is 340 pm [340 × 10^(-12) m]
Length of DNA = No. of bp × length of bp
34 × 10^-6 m = n × 340 × 10^-12 m
n = (34 × 10^-6)/(340 × 10^-12) = 100 000
The DNA molecule contains 100 000 base pairs.
If a plant loses too much water through osmosis then it becomes less rigid and the cell membrane soon will separate from the cell wall.
