1. DNA is found in all cells.
2. A gene is part of the DNA code on a chromosome.
3. Gender is defined as either male or female, except for rare species that have the ability to change sex.
To answer the first question, "DNA is found in ____ cells," you can rule out options that are not related to cells or DNA. This means you can eliminate options like "sex" and "sperm." The correct answer is "all," as DNA is found in all cells of an organism.
Moving on to the second question, "A ____ is part of the DNA code on a chromosome." Here, you can use your knowledge of genetics to determine the correct answer. A gene is a segment of DNA that contains the instructions for building and maintaining an organism. Thus, the correct answer is "gene."
Lastly, for the third question, "____ is defined as either male or female except for rare species that have the ability to change sex." Again, you can eliminate options like "competition" and "phenotype" as they are not related to the definition of male and female. The correct answer is "gender," as it refers to the categorization of individuals as male or female, with some exceptions found in certain species.
