12. Which of the following types of pathogens can only reproduce itself if it takes over host cells?
A. fungi
B. bacteria
C. virus
D. protozoa****
The answer is C.
Reason- It will take over host cells, and lay copies of itself inside the host.
The copy viruses grow and become stronger, not being able to be seen by the white blood cells that protect our immune system.
Then those copies break out of the host and repeat the process.
disagree
i think it is either C OR D
C. Virus
I think it is c too-virus
yeah maybe c
The correct answer is C. virus. To determine the correct answer, we need to understand the characteristics of each pathogen type mentioned.
A. Fungi are multicellular organisms that can reproduce themselves without taking over host cells. They have their own cellular machinery and do not need to infect host cells to reproduce.
B. Bacteria are single-celled organisms that can independently reproduce through binary fission. They have their own cellular machinery and do not need to take over host cells for reproduction.
C. Viruses, on the other hand, are not considered living organisms and are dependent on host cells for reproduction. Viruses invade host cells, hijack the cellular machinery, and rely on it to replicate their genetic material and produce new virus particles.
D. Protozoa are single-celled organisms that can reproduce independently through various methods such as binary fission, budding, or sexual reproduction. They have their own cellular machinery and do not need to take over host cells for reproduction.
Therefore, the correct answer is C. virus, as viruses can only reproduce themselves if they take over host cells.
