The Earth's atmosphere would have little or no oxygen. A by-product of photosynthesis is oxygen. Photosynthesis is the process by which green plants use energy from the sun to make their own food in the leaves. The process uses sun light, water and carbon dioxide to yield oxygen and simple sugars. The simple sugars are stored in form of starch for future use by the plants, while oxygen is either used for cellular respiration or released to the atmosphere. The process of photosynthesis adds oxygen to the atmosphere and uses carbon dioxide from the atmosphere.
Photosynthesis: 6H2O + 6CO2 ----> (yields, in the presence of sunlight) C6H12O6 + 6O2
Light Dependent:
Plants break up the water (H20) into a Hydrogen and an Oxygen (O2). The Oxygen is released through the plant's stoma. The electron from the H is energized by the sun and used in the Electron Transport Chain to make ATP.
Light Independent:
Used CO2, ATP and NADPH in the Calvin Cycle (Basically moving a bunch of Carbon and rearranging it) to eventually make a Glucose molecule (C6H1206).
<span>The 4 categories of macromolecules include carbohydrates, proteins, lipids, and nucleic acids. Carbohydrates (grains and vegetables) are the largest group at the base of the pyramid, proteins (milk, poultry, eggs, nuts) follow up the pyramid while lipids (fats and oils) are the least amount at the summit of the pyramid. </span>

</span><span>The aim of the pyramid is to recommend ideal rations for a healthy diet. Carbohydrates provide most of the energy needs for the days’ activities hence taking the largest portion. Proteins are used in building muscles, f0r nutrition, and body’s immunity hence required in lesser amounts compared to carbohydrates. Lipids help the body store energy since they have thrice as much energy as carbohydrates.They also a constituent of cell membranes and also help deliver vitamins. They are required in the least amount to avoid obesity and related illnesses such as cardiovascular <span>diseases</span></span>
To begin, you have to know what meiosis is. Meiosis is when a cell breaks into four daughter cells (like mitosis but with two extra daughter cells). Those four cells are still part of the parent cell, so they retain the genetics of the parent cell but split-up. So those cells are part of the foundations of the genetic build-up of the offspring.
