Answer:
D All of the above
Explanation:
Like our bones, bones in fish can provide general protection and support to their body.
(Fun fact, jellyfish do not have bones, so when they are out of the water, they loses their bell shape structure and looks more like a flat piece of jelly. But fish tends to look the same when it is in water and out of water.)
The bone is also where the muscles will attach to, which allows for movement.
(Imagine our fingers, the muscles in our fingers are attached to our bones, which allows us to do things like typing.)
Bones can also protect the fish's brain.
(Brain can be very fragile and soft, so having a hard structure around it can protect the brain. It's kind of similar to protecting the liquid egg in an egg shell.)
Answer:
This question lacks options, options are:
a) The partial pressure of oxygen
b) Acidity
c) The partial pressure of carbon dioxide
d) Temperature
e) BPG
The correct answer is a. The most important factor that determines the percent of oxygen saturation of hemoglobin is <u>The partial pressure of oxygen
</u>.
Explanation:
Hemoglobin is an oxygen transport protein. Partial Oxygen Pressure (PaO2), measures the pressure of dissolved oxygen in the blood, that is, it shows how well oxygen passes from the lungs into the bloodstream. A high partial pressure of oxygen in the blood produces an almost complete saturation of hemoglobin, which indicates the maximum amount of oxygen that combines, but when PaO2 is reduced, so is hemoglobin saturation, when saturation is below 90% hypoxemia occurs, that is, the level below normal blood oxygen levels.
