P - Artificial active immunity
Q - Natural active immunity
Question:
In your opinion, which immunity is the best? Why?
Anyone plz help this question...?
Answer:
The correct answer would be - natural active immunity.
Explanation:
Active immunity is the immunity that includes that develops antibody by the immune system after exposure to a pathogen naturally through disease or artificially by the process of immunization. This type of immunity is a long-lasting immunity.
If the active immunity is deliberately developed by exposure of antigen to the patient is called Artificial active immunity whereas natural immunity takes place through contact with a disease-causing agent.
In my opinion, natural active immunity is best as it is a fact that natural infection almost always causes better immunity than vaccines.
Meiosis only occur in what type of cells?
Answer:reproductive cells
Explanation: Meiosis only occurs in reproductive cells, as the goal is to create haploid gametes that will be used in fertilization. Meiosis is important to, but not the same as, sexual reproduction. Meiosis is necessary for sexual reproduction to occur, as it results in the formation of gametes (sperm and eggs).
How can evolutionary change in one species lead to evolutionary change in another species that it is associated with? Include an example to support your answer.
Evolutionary change in one species lead to evolutionary change in another species that it is associated with by adaptive mechanisms.
What is evolution?Evolution is a process of gradual cumulative changes which occurs in organisms over a long period of time resulting in the formation of new species.
Evolution in one species results in evolution in a closely related species. For example, the evolution of resistance by trees to insect pests results in similar evolution in insect pest for development of mouth parts that enables them to feed on the plants.
Therefore, evolutionary change in one species lead to evolutionary change in another species that it is associated with.
