Answer: Option D

Explanation:

During the daytime when the sun is shinning bright in the sky and the sun rays reaches the earth.

The ground becomes warm by the effect of sunlight. This is because the sun radiates huge amount of heat from its surface.

This heat reaches the earth in the form of light energy. This heat is absorbed by the earth's surface and makes it warm.

Explain why evolution is a unifying theme
Setler [38]
Unify means to make or become united uniform, or whole.

(I personally don't agree that evolution is true; but here is my answer)

Evolution is a way Scientists like to theorize the world was made/ created. They try to explain why everything can about in a uniform way. Everything has a reason or theory. Even though scientists haven't been able to prove that Evolution actually exists, many people like the idea of it- just for the reason that it gives a more believable whole approach to how the Earth and Universe came about. For some people, it is more uniform than a religion.

I hope this helped you!

posledela

Answer:

The correct answer will be option-E

Explanation:

Hershey and Chase's experiment was performed to test whether DNA serves as the genetic material or protein.

To perform experiment they grew bacteriophage into radiolabeled phosphorus and sulfur compounds. The phosphorus is an integral part of the structure of DNA whereas proteins contain sulfur in their structure.  

In the given condition if radiolabeled nitrogen is utilized then the experiment will fail as the structure of proteins also contains an amino group( NH₂) in their structure as well as DNA. The scientist will not be able to identify whether the DNA is the genetic material or protein.

Thus, option-E is the correct answer.

Complete the statements about the law of conservation of momentum.
vitfil [10]

Answer:

The law of conservation of momentum states that the total momentum of interacting objects does not change.

This means the total momentum before a collision or explosion is equal to the total momentum after a collision or explosion.

Explanation:

The law of conservation of momentum is derived from Newton's third law of motion which states that action and reaction are equal and opposite.

The law of conservation of momentum can be stated as follows.

For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.
