Environmental Protection Agency- found itself under investigation after it was discovered that it was making mutually beneficial agreements with environmental polluters.
What is Environmental Protection Agency?
President Richard Nixon issued an executive order in December 1970 creating the Environmental Protection Agency (EPA). The goal of this federal government organisation is to safeguard both human and environmental health. The EPA, which has its main office in Washington, D.C., is in charge of developing laws and standards that advance both public and environmental health.
Cosian bargaining theorem applies to EPA. The theorem states that polluter and victim can reach a mutually beneficial bargain if the damage from pollution is higher than the polluter’s net return from the sale of the good generating the pollutants.
Hence the correct option is A; Environmental Protection Agency

blood pressure is the driving force that moves fluid out of all the capillaries in the body. why is so much more fluid moved out of the capillaries in the glomerulus of the kidneys than in other areas of the body?
The capillaries in the glomerulus of the kidneys have two times more high BP than any other capillaries in the body.
What are glomerular capillaries?Blood pressure (BP) is the driving force moving fluid out of all capillaries in the body. However, unlike normal fluid moved out of capillaries, a lot more fluid is moved out of the capillaries present in the glomerulus of the kidney than other areas of the body. This is because blood pressure in the glomerular capillaries is twice as high than any other capillaries.
GBHP (Glomerular blood hydrostatic pressure) is the blood pressure in glomerular capillaries. aids filtration in the kidneys by moving water and solutes in plasma through the glomerular filter. The average GBHP is said to be 55mm Hg.
The increase in renal blood flow and afferent arteriolar dilatation increases glomerular capillary pressure. When the diameter of glomerular capillaries increase, the the tension in their walls rise. Efferent arteriole constriction will also cause increase in wall tension.

The hippocampus is a component of the limbic system and is crucial for spatial memory, which is necessary for navigation, and for transferring information from short-term to long-term memory. In both humans and primates, the hippocampus is found in the allocortex and projects neuronal fibres into the neocortex. All vertebrates have the hippocampus, which is the medial pallium.

If you do a really tough workout, you may begin to breathe hard and think that you have run out of energy. You will sometimes experience a burning sensation in your muscles. What are you really running out of when you think that you are running out of energy? Explain the process that your body is going through when you experience the “burn”.
The burning sensation during heavy exercise is due to the formation of lactic acid in muscles
Importance of heavy workout:
Although a rigorous workout is believed to be good for the body, why do muscles hurt so much afterwards? After a vigorous workout, the burning in the muscles can last for up to 72 hours. As the body adapts to the new physical demands placed on it, it grows muscle as part of the process. For muscles to be sufficiently challenged to promote growth, the body needs to be stimulated with a certain level of difficulty. The burning you experience is a necessary component of muscle development.Heavy exercise good or bad?
When you are tuned in, you will be able to sense when something is off with your body since it has innate wisdom. Although exercise might become intense, it should never be painful. Even though you will likely feel worn out and sore after working out, you will still be able to move about without agonizing discomfort.In contrast, your range of motion and capacity to carry out typical daily tasks will be significantly altered when the body experiences pain following an injury. This suggests that there might be a problem. When this happens, it is advisable to see a specialist who can fully evaluate you.
