The major food molecule in living organisms is a sugar called glucose. Most carbohydrates (sugars and starches) are converted into glucose before they are broken down in the cytosol to release energy. The series of steps where glucose is broken down to release energy begins with a metabolic pathway called glycolysis. Glycolysis is the "lysing" or cutting of glucose to release energy. The six carbon sugar, glucose, is cut in half and converted into two three carbon sugars called pyruvate. What happens next depends on the presence or absence of oxygen.
If oxygen is present, then glucose can be broken all the way down into carbon dioxide and water. This process is called aerobic respiration because it requires air (oxygen). In the absence of oxygen, the cell uses a process called anaerobic fermentation. or simply fermentation. Fermentation doesn't break the sugar down any further, it simply helps reset the system so that more sugar can be broken down.
Because aerobic respiration breaks the sugar all the way down, it releases much more energy than fermentation.
Answer:
DNA unzips between base pairs.
Explanation:
This is the first step of protein synthesis.
The process which involves informal investigations by native peoples to meet their needs is the native science discovery
Native science incorporates traditional knowledge and Indigenous perspectives, while today, non-Indigenous scientific approaches are commonly recognized as Western science. These two together is now embraced to meet people's needs
It has helped provide new ideas and dimensions on climate change, specific animal population declines, and sustainable harvesting practices.

They are our bodies preferred source of energy for everything we do and before using carbohydrates for fuel, our bodies have to break these compounds down into simple sugars.
The correct answer is A.
Animal cells do not have a cell wall.
A cell wall is the rigid, outermost covering of plant cells and is made up of cellulose. It is absent in animal cells. The cell wall is visible under a light microscope.
Animal cells are instead covered by a cell membrane. It is made up of lipids, proteins, and small amounts carbohydrates. It is a thin and delicate structure that can only be seen using an electron microscope.
