<h2>2) option is correct </h2>
Explanation:
Adipose tissue primary function is nutrient storage
- Adipose tissue is commonly known as body fat
- It is found all over the body such as under the skin (subcutaneous fat), packed around internal organs (visceral fat), between muscles, within bone marrow and in breast tissue
- Adipose tissue is composed of a variety of cell types that include mature adipocytes,endothelial cells,fibroblasts and a range of inflammatory leukocytes
- Adipose tissue is now known to be a very important and active endocrine organ
- It is well established that adipocytes (or fat cells) play a vital role in the storage and release of energy throughout the human body
- Its main role is to store energy in the form of fat, although it also cushions and insulates the body
-
Obesity in animals, including humans, is not dependent on the amount of body weight, but on the amount of body fat - specifically adipose tissue
-
In mammals, two types of adipose tissue exist: white adipose tissue (WAT) and brown adipose tissue (BAT)
- The main role of white adipose tissue is energy storage, fatty acids being released when fuel is required
- The function of brown adipose tissue is to transfer energy from food into heat; physiologically, both the heat produced and the resulting decrease in metabolic efficiency can be of significance
Sap flows when daytime temperatures rise above freezing (32 degrees Fahrenheit / 0 Celsius) and nighttime temperatures fall below freezing.
The rising temperature creates pressure in the tree generating the sap flow.
