1. The element responsible for the red color of blood is:

Correct answer: B

Rationale: Hemoglobin, the protein responsible for carrying oxygen in red blood cells, contains iron in its heme group, contributing to the blood's characteristic red color.

2. What is the difference between mitosis and meiosis?

Correct answer: C

Rationale: Rationale: - Mitosis is a type of cell division that results in two identical daughter cells with the same number of chromosomes as the parent cell. Therefore, mitosis results in two daughter cells. - Meiosis is a type of cell division that results in four daughter cells, each with half the number of chromosomes as the parent cell. This reduction in chromosome number is essential for sexual reproduction. - Option A is incorrect because mitosis produces diploid cells (cells with the same number of chromosomes as the parent cell), while meiosis produces haploid cells (cells with half the number of chromosomes as the parent cell). - Option B is incorrect because crossing over, the exchange of genetic material between homologous chromosomes, occurs during meiosis and not during mitosis. - Option D is incorrect because mitosis is not responsible for sexual reproduction; it is a process of asexual reproduction and

Expiration refers specifically to the process of breathing out air. Aspiration, on the other hand, refers to the act of inhaling foreign objects into the lungs, which can be harmful. Therefore, 'Respiration' is the most appropriate term related to 'Inhalation' as it encompasses the entire process of breathing and gas exchange in the body.
