Starvation. When the body enters starvation mode or fasting for long periods of time, the body will start to tap on the stored fatty acids to produce ketone bodies. These ketone bodies will build up in the bloodstream, and will also be available if the brain has used up the stored glucose.
Answer:
Persistent infection
Explanation:
Viruses have the ability to remain in the host cell in a dormant state or latent state for many years. This is a part of reproduction cycle of a virus called the lysogenic cycle. This causes persistent infection in the host because the virus remains in the host cell and cause infection.
This persistent infection can cause cancer in the host because the viral genome incorporates in the host cell genome and take controls on its gene machinery. For example, HPV can incorporate itself in the host genome and can alter it which can cause cancer. So the correct answer is persistent infection.
In this case, organisms in the same order are more closely related than the members of the same kingdom.
The oxygen produced by the chloroplasts passes out the cell by Cellular Respiration. So the answer would be D :)
