a) Why do we use the word vector for a mosquito? A mosquito is called a vector because it transmits disease-causing pathogens (e.g., Plasmodium) from one host to another. b) What is the name of the organism that transmits malaria disease in humans and birds? Plasmodium (a protozoan parasite). c) What was the main purpose … Read more
Complete eradication is difficult because: The Plasmodium parasite has a complex life cycle. Mosquito vectors (Anopheles) are widespread. Drug resistance in Plasmodium is increasing. Insecticide resistance in mosquitoes is growing. Some malaria-endemic areas lack proper healthcare and preventive measures. Related Questions: Define the following branches of biology and give at least one significance of studying … Read more
Yes, a hypothesis, even if proposed by a Nobel Prize winner, can be wrong. In science, hypotheses are tested through experiments and observations. If evidence contradicts the hypothesis, it is modified or rejected. Deduction: If the hypothesis is correct, then vaccinated individuals should experience fewer severe complications compared to unvaccinated individuals when infected with COVID-19. … Read more
