During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. ... Then, via respiration processes, cells use oxygen and glucose to synthesize energy-rich carrier molecules, such as ATP, and carbon dioxide is produced as a waste product.
This condensation is needed to allow the chromosomes to move along the mitotic spindle without becoming tangled or broken during their distribution to daughter cells. DNA in this highly condensed state can no longer be transcribed, so all RNA synthesis stops during mitosis.
Science literacy is essential today because a knowledge of science will help us to accurately construct the world around us. A construction of your worldview based on the scientific method, empiricism, and previous scientific inquiries is more accurate and will lead to a greater understanding of the world around you and will prevent you from falling into traps of believing in pseudoscience. Pseudoscience is an area of thought that holds certain facts or beliefs to be scientifically accurate when in fact they are scientifically unfounded.
