Question

the diagram below shows a concept map. which label correctly identifies what x represents in the concept map? 1. nucleus 2. chromosome 3. autotrophic cell 4. heterotrophic cell

Explanation:

Genes are segments of DNA. Both genes and DNA are found on chromosomes. Chromosomes also contain proteins and other materials. The nucleus contains chromosomes, but the concept - map structure indicates that X is more specific than the nucleus. Autotrophic and heterotrophic cells are types of cells and not the direct entity that contains genes, DNA, proteins and other materials as described in the map. Chromosomes fit the description of X as they contain genes, DNA, proteins and other substances.

Answer:

1. chromosome
