Answer: C. Oxygen delivery to muscle is increased when more carbon dioxide is produced by the muscle.

Explanation:

When someone is doing an exercise, for example, his heart rate increases. This increases the rate at which oxygen is carried from the blood to the muscles and carbon dioxide is moved from the muscles to the lungs, where it will be breathed out.

I’m stage 2 of photosynthesis NADP becomes NADPH why?
nignag [31]
NADPH is a reduced form of NADP+. The latter features an extra hydrogen ion in its chemical structure. When NADP+ transforms into NADPH, the other hydrogen ion  is released as part of the reaction while the other hydrogen ion becomes a part of the NADPH structure.

A plane is traveling at 80 m/s. To prepare for landing, it decreases its speed to 50 m/s in 120 s.
emmainna [20.7K]

Answer:

The deceleration of the plane is 0.25 m/s^{2}.

Explanation:

Deceleration is the converse of acceleration.

From first law of motion, we have;

v = u + at

where: v is the final velocity, u is the initial velocity, a is the acceleration and t is the time taken.

Thus,

v = 50 m/s

u = 80 m/s

t = 120 s

50 = 80 + 120a

50 - 80 = 120a

-30 = 120a

a = \frac{-30}{120}

  = -0.25

a = -0.25 m/s^{2}

The deceleration of the plane is 0.25 m/s^{2}.
