Explanation / Answer

61). Answer

The ventral tegmental area (VTA) and its widespread projections to cortical and limbic regions form the foundation of the motivational circuitry. Therefore, VTA is very essential during sex. If VTA destroyed, making bond is more difficult.

Hence, the final answer is option C It would make forming a bond more difficult

62.) Answer

Vaginal fluids are keeps the tissue moist and provide lubrication during sex. These fluids are mucous, oils and sweet glands. During sexual arousal, vaginal secretions increase due to outflow of fluid through the vaginal wall due to increased blood flow into the genital tissue.

A pair of skene glands secretes the mucus. The opening of these glands resides in close proximity to the entrance near the urethra. The Skene glands normally secrete a small amount of mucus that lubricates the urethral opening.

Hence, the final answer is option C(secretion from skene glands)
