The double-stranded dna molecule of the newly discovered elradicus libanii has a length of 34 micrometers. how many base pairs are present in this molecule?

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 the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
