Explanation:

1. Estrogen is involved in sexual maturation and regulating the menstrual cycle in pre - menopausal individuals. Testosterone is mainly male - related, thyroxin is for metabolism regulation, and cortisol is a stress hormone.
2. The brain requires glucose for energy. Low glucose levels can affect cognitive function, making it harder to think. Reproduction is not directly affected by short - term low glucose, dopamine use is not the main issue, and sleep is not the most immediate problem.
3. Tingling in the leg is often related to the peripheral nervous system which extends from the central nervous system to the rest of the body. The central nervous system is the brain and spinal cord, the autonomic nervous system controls involuntary functions, and the parasympathetic nervous system is part of the autonomic nervous system.
4. Since brown is dominant and Malek has blue eyes (a recessive trait), his parents must both have passed on a recessive blue gene to him. They both have brown eyes but carry the recessive blue gene.

Answer:

1. estrogen
2. think
3. peripheral nervous system
4. a recessive blue gene
