Answer:
A. Dissecting
Explanation:
-dissecting microscope is an optical microscope variant designed for low magnification observation of a sample, typically using light reflected from the surface of an object rather than transmitted through it.
As for the pimples that are generated in the hair follicles. <span>The overproduction of sebum resulting from the hormonal changes that Scott is experiencing is the initial event responsible for his acne. P. acnes is able to utilize the glycerol in sebum for fuel; in the process of doing so, it produces free fatty acids. These fatty acids lead to the production of inflammatory cytokines, which lead to vasodilation and increased vessel permeability. These changes allow for immune cells to move into the follicle. As the immune cells work to eliminate P. acnes, dead cells, bacterial waste, and pressure (from the massive influx of cells) will build. This ultimately distends the follicle. If great enough, this buildup will be visible on the skin as a pus-containing papule.</span>
ATP hydrolysis is the catabolic reaction process by which chemical energy that has been stored in the high-energy phosphoanhydride bonds in adenosine triphosphate (ATP) is released by splitting these bonds, for example in muscles, by producing work in the form of mechanical energy. The product is adenosine diphosphate(ADP) and an inorganic phosphate, orthophosphate (Pi). ADP can be further hydrolyzed to give energy, adenosine monophosphate (AMP), and another orthophosphate (Pi).[1] ATP hydrolysis is the final link between the energy derived from food or sunlight and useful work such as muscle contraction, the establishment of electrochemical gradients across membranes, and biosynthetic processes necessary to maintain life.
The description and typical textbook labeling anhydridic bonds as "high energy . . bonds" can be very misleading to students. These bonds are in fact relatively weak. They do involve high energy electrons but the bonds themselves are quite easy to break. As noted below, energy is released by the hydrolysis of ATP when these weak bonds are broken – requiring a small input of energy, followed by the formation of new bonds and the release of a larger amount of energy as the total energy of the system is lowered and becomes more stable.
Answer:
c) They describe the movement of water and other materials through the biosphere.
Explanation:
A biogeochemical cycle refers to the cyclic series of events. Through this process, nutrients move between the living and nonliving environment. It explains substances such as carbon, nitrogen, and water are cycled between the biotic and abiotic components of the ecosystem. The matter is cycled among the atmosphere, soil and water bodies of the biosphere. For example, the carbon cycle explains the movement of carbon between the atmosphere, living beings, soil, and the hydrosphere.
