The correct answer is D: I and II only.
Viruses have protein capsids, which protect their genetic material. This capsid sometimes is covered by viral envelopes which have glycoproteins on their surface. Glycoproteins help in the process of binding to the host cell and infecting it. In this example, virus III has the structure of a bacteriophage and it does not seem to have glycoproteins. Bacteriophages use their tail fibers to attach to the bacterial host and inject their genetic material. On the contrary, viruses I and II have glycoproteins sticking out of their envelopes.
Answer:
Yes, vaccination should be mandatory because without it all of us would slowly died from not having a cure. According to research people, they said; "vaccination will helps you to stay healthy. It also are important to your overall health such as diet and exercise."
Explanation:
The mutation was most likely the result of a change in the ability of the DNA replication.
<h3>How mutation occur?</h3>
Mutations result either from errors that occurs in DNA replication or caused by the mutagens, such as chemicals and radiation, which react with DNA and change the structures of individual nucleotides so we can conclude that the mutation was most likely the result of a change in the ability of the DNA replication.

Answer:
Thylakoids, stroma
Explanation:
The interconnected flattened sacs within the inner membrane of the chloroplast are called thylakoid. Many thylakoids are come together and get arranges in a stack called a granum.
Thylakoid contains chlorophyll pigment and is responsible for absorbing the sunlight and conducting light reaction. These thylakoids or grana are suspended in a liquid called the stroma.
The stroma contains the enzymes which are required in the light-dependent reaction. It contains DNA, ribosome, starch. The synthesis of organic molecules occurs in the stroma.
