Answer:
One of the most commonly repeated criticisms of wind power is that it kills birds. The giant spinning turbines are basically bird death traps—and often they cut through prime flying space, making the carnage even worse. At least that's the story. But how many birds really do die?
If you look around for statistics about bird deaths from wind turbines get you wildly different numbers. Some say just 10,000 birds a year
Explanation:
Ecological pyramids are graphical representations of the trophic structure of an ecosystem. Regarding these pyramids, check the incorrect alternative.
A) A pyramid is called a number pyramid when it tells you how many individuals there are at each tropic level.
B) The biomass pyramid can be inverted.
C) An energy pyramid can never be reversed.
D) The base of a pyramid is not always represented by the producer. E) A biomass pyramid represents the amount of organic matter found at each tropic level
C. is the wrong option. This is because it represented the energy fixed in each tropic level . it is never inverted because it flow upwards in the ecosystem. This energy reduces upwards the pyramid, it is largest at the base of the producers, and decreases in amount as it flow upwards from one organism at each trophic level to another. This is because each organism uses the energy for biological work
Answer:
Explanation:
Autoregulatory neural and endocrine mechanisms activate after blood loss to compensate for the loss and restore homeostasis.
Neural mechanisms involve blood pressure and blood chemistry. Cardiac centers and vasomotor centers may increase the blood flow and cardiac output (sympathetic) or decrease the blood flow and cardiac output (parasympathetic). Peripheral vessels are also constricted and nor epinephrine decreases flow in the arteries and decreases the flow in the veins.
Endocrine control acts in the renal and adrenal organs, the brain and heart. RBCs, renin/angiotensiogen/aldosterone, catecholamines, antidiretic hormone, atrial natriuretic hormone regulate blood volume and blood pressure by keeping the fluids in the cardiovascular system. It also initiates vasoconstrictors or vasodilators.
