Answer:
d. a single variable.
Explanation:
<em>A controlled experiment is one in which the researcher can can keep all other factors/variables uniform and see the effects of a particular factor/variable on certain subjects. </em>
For example, in order to determine the effects of different light intensities on the growth of a plant species. All the growth conditions will be uniform for all the subjects (the plant species) except the light intensity. Any discrepancy in growth can thus be attributed to the different light intensities.
The light intensity is varied while other factors are kept uniform.

The varieties of chrysanthemums containing all multiples of nine chromosomes are autopolyploids. Their karyotypes share the feature of an even number of basic haploid chromosome sets.
Autopolyploids are described as the chromosome sets of an individual when more than two sets of chromosomes are present. They are specifically from the same specie. They can occur when pair of homologous chromosomes have not separated into different nuclei during meiosis. Since, during meiosis, the chromosome sets are separated equally thus karyotypes have an equal number of haploid chromosomes.
Organisms with 27 chromosomes are Triploids(3n) that are sterile because Trivalents at meiosis 1 would form a high number of unbalanced gametes to be formed.
