Generally describe what forces ultimately shaped the earth into its modern form
Trava [24]

The force of gravity is a major force that created the earth.  As rocks and ice clumped together as they spun around the newly formed star (sun), the force of gravitational pull increased and attracted more debris (rocks and ice). The clumps of rocks, debris, and ice, therefore, grew into a planet.  

Another is electromagnetic force. The spinning currents in the outer core of the earth create a dynamo effect that forms a magnetic field around the earth. This shields the earth from the solar storms of the sun hence protects life and the atmosphere.

Weak nuclear force is responsible for maintaining the heat of the earth’s interior which is critical for maintaining the dynamo  effect of the outer core so the earth is protected by its magnetic field.

Answer:

It contains Uracil (U) instead of Thymine (T).

Reason for primer removal:

This is because of their uracil nucleotide which is absent in DNA. Instead of Uracil DNA contains Thymine nucleotide.

Explanation:

Primers:

Primers are a short sequence of RNA. These sequences attached to the 5' end are the requirement of DNA polymerase to start the process of replication.

Primer removal:

After replication, these short fragments of RNA are removed to replaced with DNA from the newly synthesized DNA strand.

Reason for primer removal:

This is because of their uracil nucleotide which is absent in DNA. Instead of Uracil DNA contains Thymine nucleotide.

Best Answer:

Because It contains Uracil (U) instead of Thymine (T).

How will you investigate a change in velocity affects the velocity of the two carts after the collision if the objects do not st
Nutka1998 [239]

P = mv

This is a momentum question:

Momentum is always conserved so the momentum before and after a collision must be equal so:

The velocity of the two objects after they collide and dont stick together if no KE is lost is dependent on the mass of each of the objects by:

m_{1} v_{1i} + m_{2} v_{2i} = m_{1} v_{1f} + m_{2} v_{2f}\\

Where i is initial and f is final meaning before and after the collision
