It requires carbon dioxide, water, and sunlight to yield oxygen and glucose(sugar). Cellular respiration occurs in mitochondria that are in both plants cells and animal cells. It requires oxygen and glucose to yield carbon dioxide, ATP(energy), and water. They creates a cycle in our environment since the reactants of photosynthesis are the products of cellular respiration and the reactants of cellular respiration are the products of photosynthesis. Sunlight is the only thing that is not produced by either and can only come from the sun. That is why plants must grow outside in the sunlight so that light can reach them. These two prices cause an increase in global warming because as humans deforest and remove plants from the environment an imbalance in the cycle is created. There is more cellular respiration occurring than there is photosynthesis causing more CO2 to be created than plants can use to make oxygen. So overtime more and more carbon dioxide will build up in the atmosphere is humans continue to deforest and remove plants.
Part 2:
1: Cancer cells are made from mutated cells that divide uncontrollably and this is caused because cancer is mutations in specific gene sequences. Those genes makeup proteins which control the cell cycle. So if the genes are mutated then the cycle will the changed and disrupted. When these mutated cells continue to divide they create are large buildup of cells in certain areas that are called
