Plants converts solar energy into chemical energy through the process of photosynthesis . The electron and proton from the water molecules are used to produce energy transport molecules i.e ATP and NADPH, in the light reaction phase of photosynthesis. The energy of the sun excites the chlorophyll molecule which in turn release high energy electron. The energy of ATP and NADPH is further used to fix the carbon in the Kelvin cycle.
Answer:
hey buddy I gess It will help you
Carbon dioxide is transported in the blood from the tissue to the lungs in three ways:1 (i) dissolved in solution; (ii) buffered with water as carbonic acid; (iii) bound to proteins, particularly haemoglobin. Approximately 75% of carbon dioxide is transport in the red blood cell and 25% in the plasma.
B. by the sharing of electrons
Answer choices A and C are incorrect because covalent bonds form as a result of electrons (protons are kind of irrelevant). Answer choice D is incorrect because it describes an ionic bond.
Further study topics: water polarity, hydrogen bonds, free radicals, valence electrons, and more!
Answer: <u><em>D. An observation that has a number associated with it</em></u>
Explanation: The answer is D. An observation that has a number associated with it. I would explain further, but it is pretty self explanatory.
<em>Good luck!</em>
D! The Cell membrane in found in all cells, and it is a single (mono) layer.
