Correct answer: C). Cells are the basic building blocks of life but do not constitute life itself
Cell theory in a biology is a scientific theory, which is universally accepted and it states that all living organism are made up of one or more cells, cell is the building block of living thing, it also states that all cell arise from ore existing cells.
The cell theory is collection of ideas and conclusion, which were given after many years of continuous research and experiment of many scientist, which tells about the cell and how it operates.
Answer: pH = 9.4
Explanation: in water, -log(molar concentration OH-) + -log(molar concentration H+) = 14
-log(H+) is pH
so pH = 14 - -log(OH-)
= 14 - -log(2.4*10^-5)
= 14 - 4.6
= 9.4
Cellular respiration. Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell.
The levels of cell organization go
1. cells
2. tissues
3. organs
4. organ systems
5. organisms
so the answer is D, organ level
