Cancer cells act differently to regular cells in the body. These differences are related to cell divisional behavior. For example, cancer cell(s) can multiply and grow outside the body. Regular cells can only grow inside the body. Cancer cells can trick neighboring cells into making growth factors that sustain their life. I hope this answers your question, If not, here's a link:

Answer:
B
Explanation:
Carbon atoms usually have a Lewis electron configuration of 2.4. To gain a stable electron configuration of 2.8, they usually form covalent bonds with other atoms such as another carbon and hydrogen. Carbon does not form ionic bonds because it would require much more energy for the atom to gain 4 electrons or lose the 4 electrons to achieve electron configuration. This is why carbon is a significant atom of life due to its versatility in how it bonds with other atoms including other carbon atoms. It can also form single double and triple bonds giving rise to many compounds, with the same elements, but with different properties.
I think the answer to this would be A
Answer:
atp
Explanation:
ATP is composed of ribose, a five-carbon sugar, three phosphate groups, and adenine , a nitrogen-containing compound (also known as a nitrogenous base). What class of organic macromolecules is composed of monomers similar to ATP? ATP directly or indirectly delivers energy to almost all metabolic pathways.
Answer:
(B) calmodulin
Explanation:
Calcium in cells acts as second messenger molecule which regulates the very important physiological and cellular process of cell-like neurotransmission, cell migration, secretion, fertilization and many others.
Calcium acts as a messenger by binding to a calcium-binding protein called calmodulin. Calmodulin forms complex with 4 calcium ions through the side amino acids present in the structure of calmodulin.
Thus, calmodulin is the correct answer.
