Answer:
The inhibition of the formation of the mitotic spindle leads to the arrest of cells in metaphase, stopping cancer cells from dividing. Moreover, the inhibition of the DNA synthesis may also lead to cell cycle arrest, thereby also stopping cancer cells from proliferating.
Explanation:
Vinblastine Sulfate is a natural alkaloid that binds to the microtubules of the spindle apparatus in the S phase of the cell cycle, thereby arresting tumor cells in metaphase. Moreover, vinblastine sulfate is another alkaloid drug that alters the formation of microtubules in the cell cycle (mitosis). Mitomycin C is a chemotherapeutic agent that produces interstrand DNA cross-links, thereby inhibiting DNA synthesis in tumor cells. Finally, cis-platinum is another chemotherapy agent that produces cross-links between DNA and proteins and thus arrests the cell cycle of tumor cells in the G1 phase.
<span>The correct answer is D. a viral infection. Viruses are immune to antibiotics and and can't be killed easily, so you treat the symptoms and the body establishes immunity and defeats the weakened virus. That's why once you get things like the measles once, you can never get them again after in your life.</span>
To help individuals and families compensate for high medical costs.
Answer:
Proactive interference.
Explanation:
Interference may be defined as the explanation to forget the things in the long term memory. Two main types of interference are retroactive interference and proactive interference.
The proactive interference occurs when the individual is not able to the learn the new memory because of the old task has been learnt. The memories that need to be learnt and that forgets are quite similar with each other. Students might feel the proactive interference when they learn the similar subjects.
Thus, the correct answer is option (E).
