That only the best traits would go through. The weaker trait in the animals would eventually die off.
Answer:

Explanation:
The speed increased from 2.0 * 10^7 m/s to 4.0 * 10^7 m/s over a 1.2 cm distance.
Let us find the acceleration:


Electric force is given as the product of charge and electric field strength:
F = qE
where q = electric charge
E = Electric field strength
Force is generally given as:
F = ma
where m = mass
a = acceleration
Equating both:
ma = qE
E = ma / q
For an electron:
m = 9.11 × 10^{-31} kg
q = 1.602 × 10^{-19} C
Therefore, the electric field strength of the electron is:

The thin layer of water that covers most earths surface is called the hydrosphere.
Answer:
They increase the time it takes to slow you down, which decreases the force applied to you.
Explanation:
Hope it helps :)))
The answer is (C)= zero but that it is swirling rapidly in all directions.
