Answer:Beginning with energy sources obtained from their environment in the form of sunlight and organic food molecules, eukaryotic cells make energy-rich molecules like ATP and NADH via energy pathways including photosynthesis, glycolysis, the citric acid cycle, and oxidative phosphorylation.
Explanation:
Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar. Breaking down sugar produces the energy your body needs.
I think d<span>uring sleep, a person's weight and the number of hours he or she sleeps determines how many calories do you burn sleeping. Normally, a person burns about 0.42 calories for every pound in one hour of sleep. For instance, a 150 lb. person burns about 63 calories in one hour.</span>
<span>The location in which a person is more likely to receive an echo of the soud being sent is at least 16.6. meters in front of the reflecting surface. Therefore, the answer is to this item is letter A. The speed of sound without any interference is only about 340 m/s traveling through the vibration of the media in which it passes through. </span>
Trees help maintain air quality by removing particles from the air. Trees remove a significant amount of carbon dioxide from the air. They also remove ozone and particulates that accumulate in the air. In addition to removing these particles, trees release oxygen back into the air. By removing carbon dioxide and returning oxygen, trees help maintain the balance between these gases in the atmosphere, replenishing the oxygen removed by organisms and removing the carbon dioxide released by organisms.
Answer:
Diffusion expends no energy, however concentration gradients are a form of potential energy, dissipated as the gradient is eliminated. In case you didn't know to dissipate means to disssappear, so diffusion will pretty much just edventually dissappear. It's like when you take a pack of gum out of your bookbag and everyone can magically smell it some time after you've put it away as if they're waiting till you get back to work to ask for a piece, instead it's diffusion. You slowly stop smelling it.
