He <span>is probably being treated for SLEEP APNEA.

Sleep apnea is a sleep disorder that occurs when a person stops breathing during sleep. To prevents this patients can use <span>nasal masks, which blows air into the nose while sleeping.

<span />This can happen a few times of even hundreds of times stopping the whole body from getting enough oxygen.
Answer:
If the active site is altered, the enzyme can no longer perform its catalytic activity
Explanation:
Changes in temperature or pH alters the structure of the enzyme. Enzymes have catalytic activity that lowers the activation energy required for a reaction to proceed.
Enzyme catalytic activity is facilitated by the active site - a specific region of the enzyme where the reactants bind.
At the active site, the conditions are optimal for the reaction to take place (the active site gets the reactants in the perfect position to make contact and react).
If the structure of the active site is compromised, it won't have catalytic activity anymore and won't be able to catalyze the reaction
Number 1 is fraternal (also known as dizygotic)
also sorry i don't know the second one
True
Explanation:
The ocean conveyor belt explains the cyclic nature of global water round the globe.
It suggests that cold denser water circulates and moves downward whereas warm water rises.
- The great ocean conveyor belt shows that the world's ocean is constantly circulating and mixing.
- At high latitude where temperature is low, warm water from around the equator where the sun is over head loses heat to warm the atmosphere.
- As they lose heat, they become colder and denser.
- They then sink and begin to flow southward where they get heated and rise.
- This conveyor belt is driven by salinity and temperature differences.
