Answer:
The difference between both infections is that viral infections where the virus is latent, this virus once infected is protected in the nerves of the animal organism, as for example in humans the herpes family viruses (HSV1) are housed in ganglionic terminals such as the trigeminal ganglion or the V cranial nerve, so that in a situation of immunodepression, reinfect the individual again, causing him to be unable to remove the virus from his body.
On the other hand, persistent infections diseases are the threats that persist because the microorganism cannot be eliminated, either because it is very complex, or the cure does not exist, or the correct treatment is not carried out. Furthermore, it is necessary to consider that some microorganisms mutate becoming resistant to these drugs and thus persist longer in the body until they are eliminated.
Explanation:
In short, latency refers to the fact that the individual lives with the virus for life, and persistence is that it is possible to eliminate it over a long period of time since the infectious microorganism is considered very difficult.
The source of the oxygen released into the air as a product of photosynthesis is C) Water only.
Answer:
The main function of stomach is to serve as a temporary storage chamber and primarily breaks down food by mechanical means.
Explanation:
The stomach is a muscular organ located on the left side of the upper abdomen.It secretes acid and enzymes that digest food.The stomach muscles contract periodically, churning food to enhance digestion (breaking down of food by mechanical means). The stomach is made up of several layers of tissues
The mucosa (mucous membrane) is the inner lining of the stomach.
Next is the sub mucosa.
The muscularis propria (or muscularis externa) is the next layer that covers the submucosa. It is the main muscle of the stomach and is made up of 3 layers of muscle.
The serosa is the fibrous membrane that covers the outside of the stomach.
The stomach has 3 main functions:
1.temporary storage for food, which passes from the esophagus to the stomach where it is held for 2 hours or longer
2.mixing and breakdown of food by contraction and relaxation of the muscle layers in the stomach
3.digestion of food
The stomach secretes various secretions containing enzymes which breaks down food chemically and the muscles mechanically break down the food.Food is broken down into a thick, acidic, soupy mixture called chyme, which enters the intestine.
