Frage 3 von 25

1

In 1892, Dimitri Iwanowski did a study with diseased tobacco plants that was very important for virology. This study showed that:

Wähle eine der folgenden:

Erklärung

Frage 4 von 25

1

Viruses are cellular organisms.

Wähle eins der folgenden:

  • WAHR
  • FALSCH

Erklärung

Frage 5 von 25

Frage 9 von 25

1

Wähle von der Dropdown-Liste, um den Text zu vervollständigen.

A virus has two phases. In the first stage, ( the virus is on its own, as a virion, the virus is in its original host cell, the virus eats a hole in your skin ). In the second phase, ( the virus has entered an infected cell, the virus is mutated, the virus kills the host ).

Erklärung

Frage 11 von 25

1

There are two main types of replication cycles for viruses. , the viral genome enters the host cell. , the viral genome is replicated, viral proteins are created, and the viruses assemble inside the cell then exit. , the genome is integrated into the host DNA and transmitted to the host's daughter cells.
