Answer:
Land use goes up as human population goes up. This is because the more people there are alive, the more land that people will be using. Hope this helps :)
Answer:
i think they are secondary Consumers. The majority of articles says secondary so yeah
Complex organic food molecules such as sugars, fats, and proteins are rich sources of energy for cells because much of the energy used to form these molecules is literally stored within the chemical bonds that hold them together. Scientists can measure the amount of energy stored in foods using a device called a bomb calorimeter. With this technique, food is placed inside the calorimeter and heated until it burns. The excess heat released by the reaction is directly proportional to the amount of energy contained in the food.
1. Carbohydrates
(There are 3 sources of calories (or energy), which are also known as macronutrients: carbohydrates, protein, and fat.
Of these three, carbohydrates are the body’s preferred source of energy. Carbohydrates break down into glucose, which is an immediate source of energy.)
2.
A. Bone is not a type of human body tissue.
(The human body does has 4 types of tissue: Epithelial, muscle, connective and nervous tissue).
Neural control of GFR is mediated by Sympathetic neurons that innervate alpha receptors on vascular smooth muscle causing Vasoconstriction.
<h3>How is GFR regulated?</h3>
- The sympathetic division of the nervous system regulates the GFR or Glomerular Filtration Rate.
- GFR is the sum total of filtration rates of all the working nephrons in the kidney.
- Sympathetic division comes into action when the mean arterial pressure is very low (below 80mmHg).
- In response to low blood pressure, the medulla releases norepinephrine through sympathetic nerves.
- Norepinephrine leads to activation of alpha receptors on arteries which cause vasoconstriction.
- Alpha receptors are more abundant on afferent arterioles.
- This leads to vasoconstriction (narrowing) of arteries supplying to the glomerulus.
- This decreases blood flow to glomerulus, leading to decrease in GFR.
