Homeostasis is the ability of an open system to regulate its internal environment to maintain stable conditions by means of multiple dynamic equilibrium adjustments controlled by interrelated regulation mechanisms. All living organisms, whether unicellular or multicellular exhibit homeostasis. Therefore, the correct answer is option D.

Normal body temperature is 37 degree Celsius. To convert from Celsius to Kelvin add 273. So 37 + 273 = 310 degrees Kelvin.

• In humans, the average internal temperature is 37.0 °C (98.6 °F).
• Hypothermia is a medical emergency that occurs when your body loses heat faster than it can produce heat, causing a dangerously low body temperature.
  
• Hypothermia occurs as your body temperature falls below 35.0 °C.
  
• Hence Human temperature is set at 37.0 °C.
• So, the correct answer is '37.0 °C'.

Tactile sensations are produced by the pressure receptors in the skin. The tactual sensation is related to touch.

The average human body temperature is approximately 98.6 degrees Fahrenheit, which is equivalent to 37 degrees Celsius. Option C is the standard accepted value.

Kelvin is the unit of measurement of temperature on an absolute scale. Kelvin temperature scale has an absolute zero below which temperatures do not exist. Absolute zero, is the temperature corresponds to a temperature of - 273.15° on the Celsius scale.The normal temperature of human body is 36.85$^0 $C.   

• Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different.
  
• When the body becomes hotter than the normal temperature the sweat glands releases sweat which in turns cools the skin as it evaporates. This helps the lower internal temperature of the body.
  
• So, the correct answer is 'Sweat-Thermoregulation'.

Homeothermy (the maintenance of a constant internal body temperature) is regulated by negative feedback loops, where the body detects deviations from the set point and initiates physiological responses to return to that set point.

• Core temperature is regulated by the hypothalamus (in the brain), which is often called the body’s thermostat. 
• The hypothalamus responds to various temperature receptors located throughout the body and makes physiological adjustments to maintain constant core temperature. 
• The human body regulates temperature by keeping a tight balance between heat gain(conduction) and heat loss(convention). And in humans, perspiration (sweating) is primarily a means of thermoregulation. Hence, Temperature of the human body is maintained by Perspiration, Conduction and convection and Radiation. So, the correct answer is 'All of the above'.
