Answer:
Option C, epiglottis
Explanation:
Epiglottis is a flap structure located at the larynx opening which is a separator between the upper and lower respiratory tract.
The upper part of the respiratory tract consists of Nostrils, Nasal Cavities, Pharynx, Epiglottis, and the Larynx.
After the Larynx, the upper respiratory tracts connects the trachea from where the lower respiratory tract starts. The lower respiratory tract consists of Trachea, Bronchi, Bronchioles, and the Lungs.
Hence, option C is the correct.
Answer:
High specific heat capacity.
Explanation:
The specific heat capacity of water is the quantity of heat energy needed to raise 1 kg of water by one degree.
The high specific heat capacity of water is due to high hydrogen bonds which holds water molecules together, preventing their free movements.Therefore, large amount of energy is needed to raise water temperature. The hydrogen bonds also enabled water to store energy.
This features of water makes, plasma resistant to fluctuations in body and environmental temperature, and allows biochemical reactions to occurs at relatively constant rate.

Answer:
<h2>
A</h2>
Explanation:
Testosterone is only found in males and absent in female.
Testosterone is a sex hormone in males which helps in development in primary s organs, sex accessory organs and many other organs.
Testosterone causing growth of the larynx in males only because in females this hormone is absent so sexual dimorphism was developing over time in these species.
Due to increase in growth of the larynx in males, result as adult male humans generally have large larynx and deeper voices than do adult female humans.
