Answer:
Reasoning and understanding is performed by the Pre-frontal cortex which is the part of the frontal lobe where is the other major part that deals with the implementing and planning approaches performed by the dIPFC.
Prefrontal cortex which is the part of the frontal lobe is not present in lizards and frogs, as they have limbic system which is phylogenitcaly very primitive.
The right answer is: Leptin
.
Leptin is a hormone closely linked to the regulation of energy consumption and expenditure: appetite, metabolism, and hunger.
A hormone is a protein with a messenger function. This means that once released into the bloodstream, she goes to another part of the body to transmit a message to specific receptors.
Leptin is manufactured in white adipocytes (adipose tissue) where triglycerides (fats) are stored and acts on the hypothalamus.
Answer:
Option 4
Explanation:
Folate is vitamin B and occurs naturally in various food items such as green leafy vegetable, lentils, peas, beans, in fruits such as banana, melon, and enriched products such as bread, juices etc. Folate is essential for making up genetic material or DNA. Out of all given options, option 4 has both lentil and spinach (green leaves) which are rich source of folate. Option 1 has bread as a source of folate. Hence, the correct answer is option 4.
Answer:
The number of liters, or amount of blood that circulates through all the systems of the human body is always a constant one. However, how much of the total amount of blood in the human body passes through the two major circuits (systemic and pulmonary) depends not just on the volume of blood, but also on other factors such as the size of the vessels through which the blood flows and the amount of muscular layers, or any form of tissue, that will offer resistance to that flow. Because pulmonary vessels are smaller in size, and because the need for speed in flow in that circuit is not paramount, as its purpose is to load oxygen and unload CO2 to the lungs, the mean pressure is smaller thain in the systemic flow.
Using, however, the equation on the question, to prove that mean pulmonary blood pressure is 5 times less than that of systemic blood pressure, we would have the following:
1. F= pressure/ systemic resistance
2. Flow= pulmonary flow.
3. Systemic resistance = 5x pulmonary resistance
4. Systemic pressure/ systemic resistance = pulmonary pressure/ pulmonary resistance.
5. Systemic presure x pulmonary resistance/ (5x pulmonary resistance) = Pulmonary pressure.
6. Pulmonary pressure= systemic pressure/5
