Loss of body heat that occurs through submersion in cold water is an example of which of the following?
Evaporation
Convection
Conduction
Radiation
The Correct Answer is C
A. Evaporation is the process by which heat is lost as a liquid (like sweat) turns into a gas. This is not applicable in the case of submersion in cold water, as evaporation only occurs when moisture is on the skin and exposed to air.
B. Convection refers to the transfer of heat through the movement of air or fluids. While cold water can create a convection effect on the body, the primary heat loss in water is due to conduction rather than convection.
C. Conduction is the direct transfer of heat from one substance to another through physical contact. When the body is submerged in cold water, heat is lost to the water through conduction, as the colder water draws heat away from the body.
D. Radiation refers to heat loss through infrared radiation, typically when the body releases heat into the surrounding air. This is not the primary method of heat loss in cold water.

Correct Answer is A
Explanation
A. The medulla oblongata, located in the brainstem, is directly responsible for controlling the rate and depth of breathing. It detects changes in blood levels of CO2 and adjusts respiratory activity accordingly.
B. The hypothalamus regulates various autonomic functions, including body temperature, hunger, and thirst, but it is not directly involved in the control of respiration.
C. The midbrain is involved in functions such as vision, hearing, and motor control, but it does not directly control respiration.
D. The cerebellum is responsible for coordinating movement and balance, but it does not regulate respiratory control.
Correct Answer is D
Explanation
A. Hydrochloric acid is a strong acid produced in the stomach to aid in digestion, not a byproduct of glucose breakdown.
B. Ketotic acid is produced in conditions where fat metabolism predominates, especially during ketosis, not during anaerobic glucose breakdown.
C. Carbonic acid forms when carbon dioxide dissolves in water and is not related to glucose metabolism.
D. Lactic acid is produced during anaerobic respiration when glucose is broken down without sufficient oxygen. This occurs in muscles during intense exercise, leading to the accumulation of lactic acid, which causes the sensation of muscle fatigue. This is the correct answer.
