The unit of measurement in an ecological footprint is the global hectare.
Answer:
Most fish use gills for gas exchange instead of lungs.
Explanation:
Answer:
Consider the arteriolar end of a capillary bed. During capillary exchange, the process of <u>filtration </u>is favored at the arteriolar end due to the higher <u>hydrostatic</u> pressure.
Explanation:
The <u>net filtration pressure</u> at the arteriolar end of the capillary bed is more than 10mmHg. That is why the fluid exits capillary since <u>capillary hydrostatic pressure</u> is 35mmHg that is greater than <u>blood colloidal osmotic pressure</u> which is 25mmHg.
Hence during capillary exchange, the process of <u>filtration </u>is favored at the arteriolar end due to the higher <u>hydrostatic</u> pressure.
The caloric value of food refers to the amount of energy that is produced as a result of complete combustion of that food under normal conditions.
Foods have energy which are stored in the chemical bonds that hold their molecules together. This stored energy is released when the chemical bonds are broken during metabolic processes such as respiration. The amount of energy in different foods differ and the quantity of energy in the chemical bonds that hold the food molecules together will determine the amount of energy that will be obtained from the food.
In most food molecules, the chemical bond that hold the food molecules together is C-H bond. C-H bond is a strong covalent bond which give stability to the food molecule. The higher the chemical energy that is stored in this bond, the higher the caloric value of food. Thus, the calorific value of food is depended on the quantity of energy that reside in the C-H bond.
