Answer:
X shapes in the illustration can be either one or two
Step-by-step explanation:
Since a human cell has 46 chromosomes, we can determine the number of X shapes in the illustration in Figure 1.9 by understanding the structure of chromosomes in humans.
In a human cell, chromosomes exist in pairs, with each pair containing two chromosomes. One of these pairs is the sex chromosomes, which determine an individual's sex. Females have two X chromosomes (XX), while males have one X and one Y chromosome (XY).
Based on this information, if the illustration in Figure 1.9 were of a human cell, the number of X shapes would depend on the sex of the individual. If the cell belongs to a female, there would be two X shapes, representing the two X chromosomes. If the cell belongs to a male, there would be one X shape, representing the single X chromosome.
