Explanation:
The high energy radiation causes damage to the cancer cell’s genetic material by inducing double-stranded breaks in their DNA. This acts as a signal for the cells to begin the process of apoptosis – induced cell death. The cancer cells then are unable to reproduce and die.
However the radiation my reach neighboring healthy cells and also destroy their DNA. If these genes for apoptosis are also damaged in the process then the cells may begin dividing with damaged genetic material resulting in more cancer.
Answer:
A. 1:1
Explanation:
The ratio of metal cationic (+) atom to nonmetal anionic (-) atom in the sodium and bromine compound is 1:1 because sodium needs to lose one electron and bromine needs one electron to become stable and complete its outermost shell. When sodium lose electron, it become cation and gain +1 charge while on the other hand, the bromine accept one electron and become anion and gain -1 charge so that's why we can say that there is 1:1 of metal cationic (+) atom to nonmetal anionic (-) atom in the sodium and bromine compound.
Answer:
Explanation:
An oxidizing accepts an electron and becomes reduced while a reducing agent loses an electron and become oxidized.
Chemical equation:
1) 2 N₂H₄ + N₂O₄ → 3 N₂ + 4 H₂O
2) Hydrazine ( N₂H₄) is being oxidized
Dinitrogen tetroxide N₂O₄ is being reduced
3) The reducing agent is Hydrazine ( N₂H₄) and the oxidizing agent is dinitrogen tetroxide (N₂O₄)
Answer:
A substance that is dissolved in a solution is called a solute
Explanation:
Solute is the substance which is dissolved
Solvent is where you dissolve the solute (usually liquids)
Solution = Solute + solvent
Answer:
velocity
Explanation:
velocity has both speed AND direction.
