Typically, gametes are haploid cells. They only contain a portion of the chromosomes because as they intertwine with the meeting gamete the other half of the chromosome will ideally fit the other half of the cell and fertilization will occur. Moreover, when a sperm or egg cell has already a complete chromosome or is diploid no fertilization will happen.
Her metabolism reduces so as to reduce the amount of heat the body is producing. This reduces the risk of overheating/hyperthermia. During metabolism, approximately 60% of the energy produced is released as heat. This coupled with the high temperatures in the classroom increases her core temperatures. Due to the reduced metabolism, Anna feels sleepy since the body processes become slow in a homeostatic feedback response.
