ATP B. oxigen Chydrogen in E carbonExplanation / Answer
1. B
Chemical makes up for biomolecules and other chemical substances present in a cell. Cellular refers to cell, cells gather to make tissues, tissues make organs, organs make organ system which makes up the entire organism
2. It's called a principle.
3. Water molecules are charged and polar. As oxygen is more electronegative it pull the electrons because of which it carris a negative charge and hydrogen carries a positive charge.
4. Organic molecules contain carbon
5. B
6. Cell. It's the structural and functional unit of life
7. Bacteria, archae and eukarya- three domains
8. A membrane bound nucleus
9. Protein synthesis
10. All statements are true
11.dna
12. Metabolism
13. Proteins
14.atp is the energy currency of the cell
