Question

1. chemotherapy is a treatment of cancer that involves a) using a beam of radiation directly on the tumour b) using a beam of light directly on the tumour c) physically removing the tumour through surgery d) drugs taken orally or injected to target all dividing cells e) changing the dna of the affected cell so it stops dividing 15. the following is the correct order of mitosis a) prophase, metaphase, anaphase, telophase b) telophase, metaphase, anaphase, prophase c) metaphase, anaphase, prophase, telophase d) anaphase, metaphase, telophase, prophase

Explanation:

1. Chemotherapy involves using drugs taken orally or injected to target all dividing cells to stop cancer - cell division. Option d is correct as it describes the use of drugs for this purpose.
2. The correct order of mitosis is prophase (chromosomes condense), metaphase (chromosomes line - up at the equator), anaphase (sister chromatids separate), and telophase (nuclear envelopes reform). So the order is prophase, metaphase, anaphase, telophase, which is option a.

Answer:

1. d. Drugs taken orally or injected to target all dividing cells so it stops dividing
2. a. Prophase, metaphase, anaphase, telophase
