Answer:

High-dose chemicals can damage DNA causing genotoxicity, which is defined as damage to DNA or genes. And this can be aggravated since many chemicals have had little toxicological evaluation.

Explanation:

The cancers are caused by mutations in the DNA throughout the life of a person, in such a way that obeying the causative factors, in this case the chemicals, they leave a mutational pattern in the genome of each tumor. There is an interesting biomarker called TGx-DDI, which is based on some genes that are expressed in a cell subjected to the stress produced by the chemical compound. These genes reflect the way in which different pathways can provide information on how cells respond to the chemical.

Alexus [3.1K]

The vascular bundle in the shape of a single central cylinder in a root is called the Stele.

  • Vascular bundles provide the following purposes: 1. Xylem: It is essential for delivering water-related elements to various areas of the plant. 2. Phloem: This tissue is in charge of delivering nutrients and food to the plant. 3. Cambium: By producing new xylem and phloem, it contributes to secondary growth in plants.
  • A group of fundamental tissues found in the stem of a plant that includes cambium, xylem, and phloem. The procambium of the developing stem is where the vascular bundles grow. In the monocotyledons, vascular bundles are scattered throughout the stem in intricate configurations.
  • The major vascular system of the plant axis and its accompanying ground tissues make up the plant stele.
