The most basic definition of cellular respiration is that it is cells breaking down food to make energy. True or false?

fredd [130]

Answer:

True

Explanation:

In cells, energy is obtained from food through the process of cellular respiration. In mitochondria, this occurs through aerobic respiration- here, cells breakdown sugars like glucose into carbon dioxide and water and energy in the form of ATP or adenosine triphosphate.

In cellular aerobic respiration:

C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP

1. Natural selection is the best of the organisms to live past hardships and survive, leaving the weakest to die. Survival of the fittest.

2. Adaptation is an organism changing to better themselves in a certain environment.

3. These moths were adapted to blend into their surroundings, so as to not be seen by predators.

4. Because of the pollution from the city, the tree’s bark turned from a lighter shade brown to a darker shade brown.

5. A majority of the moths were a lighter gray. With the changing color bark they were seen more by predators.

6. Adaption caused the first darker moths to appear because they learned they needed to blend into the new tree bark color.

7. The change from light to dark gray was very needed for moths. It explains natural selection for those moths who did not adapt to different color gray. Adapting the new tree bark color helped moths been less seen by predators therefor keeping their species more alive.
