Answer:
D) The virus has entered the genome of the bacterial cell and is in the lysogenic stage.
Explanation:
Virus have two reproductive cycle lytic and lysogenic cycles. In the lytic cycle, the viral genome is expressed using the host molecular machinery and make capsid proteins. These capsid proteins surround the viral genome and make new phages which lyse the host cell and gets released.
After the release, they enter their genome in other host and that genome first incorporates in the host genome and replicates with the host genome. This cycle is called the lysogenic cycle and in this cycle lysis of cell does take place because no new phages are produced in it.
Answer:
The correct answer is - mitochondria lack ribosomes like prokaryotes.
Explanation:
The Endosymbiotic Theory says that mitochondria and chloroplast in eukaryotic cells are developed by the once aerobic bacteria that were engulfed by a large anaerobic bacteria.
This theory suggests the origin of eukaryotic cells. Various evidence exists such as mitochondria and chloroplasts contain their own circular DNA like prokaryotic cells and mitochondria and chloroplasts have 70S ribosomes like prokaryotes have.
The answer to this question would be: start doing CPR.
If the victim becomes unresponsive, probably the foreign body completely obstructs the airway and the oxygen level is already too low. Without the victim help, taking out the foreign body will be hard.
In this case, CPR will be the best option since the pressure from chest might push the foreign body away and the CPR can help circulate the blood.
