Answer:
New discoveries in the treatment of cancer do not only centre on conventional medicine. In our haste to get to grips with a cure for cancer, natural products may be overlooked and dismissed in the fight against such an aggressive disease.
In December, the Academy of General Dentistry reported that a new study had found that simply swishing green tea around the mouth halts the growth of new oral cancer cells and breaks down and kills existing oral cancer cells. The antioxidants (polyphenols) in the tea work to remove the free radicals or oxidants and prevent gene mutations, and as an added bonus, the polyphenols can kill cancerous cells without harming normal cells and inhibiting their growth. Similarly, a chemical found in tomatoes may prevent or treat oral cancer and one derived from soybeans has been found to shrink abnormal growths that lead to cancer. While these are not cures, their activity may in the future lead to therapies that compliment conventional treatment modalities.
Perhaps combining ancient remedies with Western scientific advances is the way forward to finding an effective cure for cancer. Combrestatin – a cancer-fighting drug made from the bark of an African tree – is performing with dramatic effects in tests. The active ingredient extracted from the bark attacks the blood vessels that grow with tumors, while leaving normal blood vessels alone.

question 8
DNA is copied into mRNA during the process of <u>Transcription</u>
- <u> </u>Transcription is the process by which information in the strand of DNA is copied into new molecule of messenger mRNA.
- The mRNA formed is a complimentary to DNA strand whereby replace of C with G, and A with U and T with A.
Question 9
Translation occurs in the ribosome , the organelle responsible for building proteins.
- Ribosome are responsible for protein synthesis.
- They receive messenger RNA sent from the nucleus and build protein.
- translation has three steps that is
- initiation - ribosome assemble around the target mRNA.
- elongation- The tRNA transfer amino acid to tRNA corresponding to the next codon.
- Three phases of translation initiation polymerase bind to DNA strand and move along until the small ribosomal subunit binds to DNA.
The answer is D, white blood cells.
The main function of white blood cells is to defense the body from bacteria or other pathogens. There's 2 main kinds of white blood cells, lymphocytes and phagocytes. Lymphocytes mainly produce antibodies that can kill bacteria or any pathogens, and phagocytes can ingest the pathogens directly.
Therefore, since the white blood cells can protect our body, they're part of our immune system.
Hi. excuse me sorry but i cant see your question. do you think you could post it again, please?
thank you
