Answer:
D
Explanation:
The correct answer would be that the origin of all cells can be traced to previous or pre-existing cells.
According to the cell theory which is made up of three parts;
- <em>The cell represents the basic unit of all life.</em>
- <em>All living organisms are made up of cells.</em>
- <em>Cells do not arise spontaneously, but only from pre-existing cells.</em>
Hence, the discovery that the origin of all cells is traceable to previously existing cells supports the latter part of the cell theory.
The correct option is, therefore, D.
The genes that survive and flourish in a species are the strong ones. Strong genes evolve into the next generation, while weaker ones die.
Cellular respiration associates oxygen with glucose within the mitochondria to generate ATP; water and carbon dioxide are generated as well. Photosynthesis utilizes energy from sunlight to produce glucose and distinct oxygen from carbon dioxide and water.
The cellular respiration uses the outcomes of photosynthesis and photosynthesis utilizes the outcomes of cellular respiration at its initial stage.
Both the process of cellular respiration and photosynthesis exhibit an equal enthalpy. Thus, the correct answer is option A.
