Answer:
Viruses use their own catabolic enzymes.
Explanation:
Viruses are the infective particles present in the environment which encloses their genetic material which could be wither RNA or DNA enclosed in the protein coat.
The protein coat is made of the capsomers which are arranged in the tubular structure forming capsid. The viruses do not contain the metabolic machinery of their own that is the reason that they do not have replication or transcription or translation machinery. For this they are dependent on the host organisms as they use their machinery.
Thus, the selected option is correct.
Answer:
I believe the answer to this question is b observable physical evidence.
Explanation:
The reason for this is because scientists make predictions and use evidence to back up their hypothesis. If the evidence doesn't support their claim, they make up a new one, until they have gathered enough evidence to support their claim. This can be done through past knowledge, like failures and successes and lab experiments, so it is not only each of them, so the answer cannot be c or d. Out of the two options, a and b, I just thought about it and picked b as the reasonable answer. Please give me feedback on the answer, if it is right or not. Thanks! Hope I helped!

The best answer to fill in the blank would be the third option C) Antibodies which in the name anti means against, so since the word anti is the same as against, its a battle between antibodies and invaders, so that's why its C).
