The person should be a male.
Only male carries XY chromosomes, meanwhile female carries XX chromosomes. "Heterozygous for the X and Y chromosomes" means that the person have both X and Y chromosomes in their cells, therefore only males fits the description.
This is also why the birth rate of girl or a boy is always 50%, it is because the sex of a person is only determined by the sperm from a male. Each sperm either carries a X or a Y chromosome, never the both. Therefore, the chances of a X or a Y sperm fertilising an X egg is always 50%, also explains why both female or male must have at least one X chromosome because an egg always carry an X.
Answer;
-Photosynthesis
Explanation;
-Photosynthesis is referred to as the process where plants use energy from the sun, carbon dioxide, and water to make food. Photosynthesis is largely responsible for maintaining and producing oxygen content of the atmosphere of the earth and then supplies all organic compounds and energy which is necessary for life.
- Carbon dioxide may be removed from the atmosphere when it is used by plants and algae for photosynthesis, dissolved in water, or deposited in the sediments on land or in the ocean. During photosynthesis there is photosynthetic conversion of carbon dioxide into carbohydrates by plants, releasing oxygen in the process.

Answer:
Homeostasis
Explanation:
Homeostasis is the maintenance of a steady-state/condition in the body to ensure the optimal workings of the cells. Blood sugar level is one of the variables in the body that also has to be maintained through positive and negative feedback loops to maintain the desired level. Insulin is the hormone used for negative feedback (to reduce the blood sugar level when it goes higher than the normal level) and Glucagon is the hormone for positive feedback (to raise the blood sugar level when it goes below the normal levels).
