It is known as the Boulder dam and it is a concrete arch-gravity dam
<span>Chemical weathering occurs more rapidly in a hot and wet climate. Chemical processes like chemical weathering happens rapidly during high temperature, specifically during warm but damp climates. So, on the first question, the answer is letter A. On the second question, the statement that best describes rill erosion is letter D. Rill erosion is the removal of soil by a running water that cuts and forms small channels into a slope or streamlets.</span>
In the light dependent reactions light energy is absorbed by the photosytem II and an electron is released. This electron causes a process called photolysis to occur(H20-->2H++2e-+1/2O2). This is how O2 is released in the atmosphere. The electrons resulted from photolyisis enter the electron transport chain. In the electron transport chain using the energy in the elecrtons, hydrogen protons are pumped inside the thylakoid. Those protons accumulate to form an electrochemical gradient. That means the protons need to flow out, and they do through an enzyme called ATP-synthase which turns ADP and inorganic phosphate into ATP and water. In the electron transport chain, the electrons reach Photosystem I where NADP+ is reduced and becomes NADPH.
ATP and NADPH store the energy absorbed in the light dependent reactions. Those two molecules are needed when CO2 is fixated in Calvin's cycle to synthesize glucose.
Answer:
PROMOTER is a DNA sequence where RNA polymerase binds and begins the process of transcription. ENHANCER is a D N A sequence that binds regulatory proteins that interact with promoter-bound proteins to activate transcription.
