Answer:
From food
Explanation:
Food energy is a chemical energy used by humans through the process of cellular respiration. Food contain macromolecules such as lipids, proteins, carbohydrates, water, vitamins, and minerals that are necessary for the human metabolism and they are broken down and used by the series of metabolic steps (glycolysis, Krebs cycle, electront transport chain and oxidative phosphorilation). Digested macromolecules should be used either as a source of energy or as building blocks for the cell.
At the end of catabolic processes within an organism food energy is transformed into energy usable by the cell-ATP.
Theory relates to a model in science because it presents the possible paradigms and patterns of the said concept and fact. It explains and elaborates the phenomenon of why it happened, how it happened and the factors that are involved in the process. A theory is a possible explanation of certain occurrence.
In addition, any time a scientific theory is challenged, it means it's not a good theory. And this statement is not valid. In theoretical models, they are revisited when there are further studies and discoveries found in a certain area where they can be remodeled and reintegrated instead of disregarding its credibility. Models, theories, and paradigms are not challenged but rather encouraged, they are supported in many studies since these theories and models were created in order for us to understand a certain phenomenon but it would likely help the scientific society to be updated in the new forms or spheres of improvement rather than discouragement. <span> </span>
Answer:
Cell types I and III are animal and fungal cells, which are most closely related since they are eukaryotic cells that are heterotrophic. Eukaryotic cells include plants, animals, fungi, and protists.
