<span>The situation shown consists of a picture with the sun emitting light energy; and a plant both absorbing carbon dioxide and emitting oxygen. The missing reactant in order for photosynthesis occur is water. Plants absorb water from the soil (through roots) and absorbs ligth energy from the sun (through leaves). The energy absorbed is used to split water molecules into H2 and O2. Then H2 combines with CO2 to form glucose. The answer is the option A) water.</span>
Answer:
{Dear:friends name}
I'm writing this letter to tell you congrats on getting admitted into your dreams school!!
I know how nervous you were when the letter came.
i'm going to miss seing you around but i know that you are going to have so much fun when school starts up again .

9. I'm sorry I don't understand this question.
10. Tissue
11. Cell specialisation
12. 46, 23
13. ATP, idk the other blank sorry
14. A
15. The main function of the Krebs Cycle is to produce electron carriers that can be used in the last step of cellular respiration.
16. The light-independent reactions, or dark reactions, of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose. These reactions occur in the stroma, the fluid-filled area of a chloroplast outside the thylakoid membranes.
Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.
17. Aerobic respiration takes place in the presence of oxygen, produces a large amount of energy. Carbon dioxide and water are produced as the waste products. Anaerobic respiration takes place without the use of oxygen, produces small amounts of energy.
<span>The organelle responsible for the synthesis of fatty acids and steroid hormones is called smooth endoplasmic Reticulum. The smooth endoplasmic reticulum, or smooth ER, is an organelle found in both animal cells and plant cells. It's main function is to produce lipids (fatty acids) and steroid hormones.Smooth ER also makes or distributes products according to its location. In muscle cells, it releases calcium ions because they are required for muscle contraction. In cells of the endocrine system, which is responsible for regulating hormones, smooth ER makes steroid hormones.</span>
