Mutagens increase the likelihood of mutations in DNA.
A mutagen is a chemical or bodily agent able to induce adjustments in DNA referred to as mutations.
Mutations end result both from mistakes in DNA replication or from the dangerous outcomes of mutagens, along with chemical compounds and radiation, which react with DNA and trade the systems of person nucleotides. All cells possess DNA-restore enzymes that try and limit the range of mutations that arise
Examples of mutagens encompass tobacco merchandise, radioactive substances, x-rays, ultraviolet radiation, and an extensive sort of chemicals.

Complete question:
The movement of auxin from the apical to basal sides of immature leaf cells and toward the xylem and phloem of the stem is an example of _____ transport.
polar
trophic
paraxial
bidirectional
Answer:
Polar
Explanation:
Auxin is one of several plant hormones. It is a group of several natural and synthesized plant hormones. Auxin is mainly produced in the apical meristem of the shoot. The synthesized auxin in shoot meristem moves downwards along the axis of shoot and root. Since this movement occurs in one direction only, it is also called unidirectional or polar movement. It is always transported downwards. Auxins are also produced in young leaves and seeds.
