Explanation:

• For Question 6: Residual air in the lungs maintains lung volume and allows for continuous gas - exchange between breaths, preventing collapse.
• For Question 7: In the follicle stage of the menstrual cycle, follicles develop in the ovary, and the endometrium thickens in preparation for potential implantation. Ovulation (release of an ovum) occurs during the ovulatory phase, and endometrium shedding occurs during menstruation.
