Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When organisms are cold, they begin to shake/shiver. What process does this represent?
A
Photosynthesis
B
Homeostasis
C
Diabetes
D
Cellular Respiration
Explanation: 

Detailed explanation-1: -A Thing Called Homeostasis As part of the process of homeostasis, shivering is one way that your body tries to produce more warmth and make up for all the heat it’s losing to the cold air.

Detailed explanation-2: -When the hypothalamus senses that you’re too cold, it sends signals to your muscles that make your shiver and create warmth. This is called maintaining homeostasis. The hypothalamus also maintains homeostasis in lots of other ways, such as by controlling your blood pressure.

Detailed explanation-3: -Homeostasis is defined as the regulation of biological systems such as temperature, blood pressure, etc., in response to changing environmental conditions. Sweating is an example of homeostasis as it helps regulate our body temperature.

Detailed explanation-4: -Shivering is one of the many automatic and subconscious functions that the body performs to regulate itself. Other so-called homeostatic functions include the adjustment of breathing rates, blood pressure, heart rate and weight regulation. Shivering is essentially the body’s last-ditch effort to keep itself warm.
