The word tracheostomy refers to an opening through the neck into the trachea through which an indwelling tube may be inserted. true or false?

This is true. A tracheostomy is a procedure where an opening is created in the neck into the trachea, otherwise known as the windpipe, and a tube is inserted into the trachea and it allows air to enter into the lungs. This is done on a short term basis or long term, When someone is choking and no other means of alleviating the blockage has been achieved a tracheostomy can be done to allow the person to breathe, the tube is then removed once the blockage has been removed. In addition in the long term when people have diseases that have impaired the ability to breathe effectively on their own a tube is inserted directly into the lungs through the trachea to bring oxygen into the lungs, such diseases include throat cancer.

explanation:

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
