Answer:
velocity = 3 m/s
Explanation:
kinetic energy = 1/2 * mass(kg) * velocity²
Using the formula:
18 = 1/2 * 4 * velocity²
9 = velocity²
velocity = 3 m/s
If you want to prevent yourself from being bias you must not base anything off of your opinion, or what you think is the right answer.
Everything must be strictly facts with no intention of trying to persuade the reader. If you truly believe that you need something in your paper, make sure you can support your claim with actual facts (it is very important that you back up all of your claims with actual facts)
Refrain from using things like:
•In my opinion
•I think
•I believe
•I know
•Everyone knows that
Undergo differentiation

turn on all of the genes found in the nucleus

Answer:
Option-C
Explanation:
Scientists found a fossil of a fish with four limbs or legs. The fossil was estimated to be around 375 million years old.
The fossil showed the fins and scales of a fish but they also possess the bones of proto-wrist, shoulders and the elbow.
The presence of these bones can be a clue that the fish evolved the limbs to walk on the land and will later evolve into animals belonging to amphibians, reptiles and mammals. Therefore, the Tiktaalik is considered the missing link of how life evolved from water to land.
Thus, Option-C is correct.
Answer:
the tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes.
