Answer:Through the Left ventricle
Explanation:
.
Anatomically, the left ventricle empty directly into the aorta. Therefore the probe will pass through the aortic valve to exist in left ventricle.
The left ventricle pumps oxygenated blood out of the heart through the aorta into the systemic circulation. Consequently, there must be a closed link between the chamber which stores and empty the blood (left Ventricle), and the vessel which conveys blood to the target areas (Aorta) in the systemic circulation.

Answer:
1) Refrigerate or freeze
If you freeze or refrigerate the food, the bacteria or whatever organism growth will slow down in the food by a Greta amount due to the coldness. Refrigerate might be a temporary food soteage for like a week or 2/ month max. While freezing will just freeeze the bacteria and mold on the food which can be stored up to 3- 12+ months even. But then again it will be most likely flavorless by the end or have no nutrients value. You can stores mik in the freezer for a while but its not recommended to taste, same for other thing syou usually see in the fridge, eggs/ vegetables/fruits/ milks/ yogurts/ etc.
2) No moisture, no water of any kind (drying in the sun or salted)
So every living thing we know of needs water. Including bacteria and mold. Without water, theres no place to thrive. No place to thrive means no bacteria and food is safe for a good amount of time. Dried foods can last a really long time, sure some types are really unpleasant but its edible. But you can’t techincally “dry” meat since it will be A whole nest for flies before it even reaches the halfway mark. You can slat it which will lessen he time but still really efficient. Salt absorbs water and breaks down any type of Stuff. Its like a mini acid.
3) Canned good and no air access (Pressurized/ controlled container)
This is done by putting all your favortie food in a metal container. With no air access, the bacteria or mold in the food already in can’t escape and new ones can’t get in. THe can then is boiled to a certain tempature where then the bacteria dies. Now the food can even be perishable stuff like meat (most common fishes), fruits and even a nice can of liquid soup. Nothin g can get in. Nothing can get out but nothing CAN get out becuase eveythign is dead. Canned food can last REALLY LONG, good for long term expeditions without a fire or food.
Answer:D
Explanation: The pulmonary air sacs of birds only permit a unidirectional flow of air through the lungs. Unidirectional flow means that air is inhale and exhale through one trachea alternatively. This means the bird lungs only receive largely fresh air which has a high oxygen content during inhalation and do not receive fresh during exhalation. While air flow bidirectional in mammals.
Answer:
Francesco Redi's experiment was the first experiment that disproved the theory of sponatenous generation. He explained that life cannot originate from the inorganic or non living matter.
He placed the two maggots in two different jars. The one jar is uncovered and contains meats in which maggots appear. The another jar is covered and no maggots appear on meat. This explains that maggots flies eggs are not formed in the covered jar as eggs are not available for the life. Maggots do not originate from the meat.Life originate from the pre existing life.
