The amount of carbondioxide in the atmosphere would greatly increase if there were fewer plants.
(Plants) is the answer.
Most likely a silent mutation. Silent mutations are mutations in DNA that do not have an observable effect on the organism's phenotype because the same amino acid is produced regardless of the change in the nucleotide sequence by the mutation.
I believe the answer is The spindle fibers
Microtubule will form the spindle fibers that will grab the chromosome. The formation of microtubule will be start from prophase and it will have role in moving the chromosome through the metaphase and anaphase. If the substance disrupting the formation of microtubules, then spindle fibers will not be formed.
Because electrons are “pulled” towards the oxygen.
