These had no leaves or roots, instead they had green photosynthetic stems which served as both anchors in the ground and photosynthetic surface.
Answer: 6CO2 + 6H2O -> C6H1206 + 6O2
Explanation: This is a balanced chemical equation for photosynthesis. In photosynthesis, six molecules of carbon dioxide react with six molecules of water in the presence of sunlight to form one molecule of glucose and six molecules of oxygen. Photosynthesis is a process by which green plants manufacture their own food using sunlight. Plants cells have an organelle known as chloroplast which contains chlorophyll a green pigment that traps energy from the sun. The energy trapped by the chlorophyll is used by plants in the presence of carbon dioxide and water to drive the synthesis of glucose with the release of oxygen as the by-products.
Answer:
This happens because your body needs iron to make a protein called hemoglobin, which is found in red blood cells. Hemoglobin helps carry oxygen around the body. When your body doesn't have enough hemoglobin, less oxygen reaches your tissues and muscles, depriving them of energy.
