Answer:
volume = 0.285 L
Explanation:
Henry constant is given as

Where C is concentration
P is atmospheric pressure

when atmospheric pressure 4 atm


In 5 litere blood , moles of N_2 

At surface moles 
Moles of N_2 release = 0.014 - 0.0028 = 0.0112
Mass of 
T = 37 + 273 = 310 K


volume = 0.285 L
Vertebrata
Vertebrata is a group that contains various organisms which possess vertebrae (backbones). Animals that belong to the group are called vertebrates, and they include mammals, birds, fish, amphibians, and reptiles. The backbones in the animals extends from the head to the tail, and it encloses and protects the main nerve cord. The body of vertebrates is divided into trunk, and tail regions. They also possess a unique tube shaped brain, a distinct head, and three pairs of sense organs.
Answer:
The dotted line most likely represent C NADH and FADH2
Explanation:
NADH is a reducing agent formed during glycolysis and TCA cycle. FADH2 also act as electron donor or reducing equivalent generated only during TCA cycle.
NADH and FADH2 are reduced form of coenzyme NAD+ and FAD. NADH and FADH2 formed during glycolysis or TCA cycle, enters into the electron transport chain(ETC) to perform oxidative phosphorylation that deals with reduction of oxygen(O2) to water(H2O) along with the formation of energy in form of ATP.
