A) An organism with favorable genetic variation will tend to survive and breed successfully.
Explanation:
In an ecosystem, organisms that don't have the best genetic variation will die off, leaving the more genetic favored ones to survive and become better as a whole.
I’m pretty sure it’s kinetic energy
The difference between them is in regard to what spins and what is fixed. In an alternator<span>, electricity is produced when a magnetic field spins inside the stator (windings of wired) </span>
Answer:
3 kg
Explanation:
Momentum before = momentum after
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
After jumping on the skateboard, the student and the skateboard have the same velocity, so v₁ = v₂.
m₁u₁ + m₂u₂ = (m₁ + m₂) v
(47.4 kg) (4.2 m/s) + m (0 m/s) = (47.4 kg + m) (3.95 m/s)
m = 3 kg
<span>The correct answer is: Oxygen
Explanation:
In order to function properly (movement etc.) during exercise, muscles require oxygen. During exercise, the depth as well as the rate of breathing increase, which in turn increases the amount of oxygen inhaled. In order to expand and contract lungs and for other bodily movements, muscles require oxygen, and for that, more oxygen is carried in the blood to muscles. Hence, the correct answer is Oxygen.</span>
