 Edwin Hubble's observation of galaxies revealed that the light received from them were red-shifted, indicating that they are moving away from us. And the seemingly farther away a galaxy was, the greater its red-shift. This can only be explained if a all the galaxies were expanding outward. Determining the exact distances to the other galaxies was a problem, however, until the Hubble space telescope. It had high enough resolution to identify Cepheid variable stars in other galaxies, and accurately determine their distance, and therefore the expansion rate of the universe.eelfins <span>·

What are the three examples to justify Newton first law of motion .​
Sergeu [11.5K]

Explanation:

1.Law of Inertia

<em>Inertia</em><em> </em>: is the ability to resist change in motion.

<em>Example</em><em>;</em><em> </em><em>if you roll a ball it will keep running unless you</em><em> change </em><em>it's</em><em> </em><em>direction with the help of </em><em>friction.</em><em>.</em>

2. second law of motion states that an object will accelerate when an unbalanced force is applied on a mass..

<em>unbalanced force is a type of force</em><em> where total force</em><em>≠</em><em>zero</em><em>,</em><em> </em><em>means the object will move</em><em>.</em><em>.</em>

<em>Example</em><em>;</em><em> if you will try to push a truck</em><em> will be less but if you push a car the acceleration will be more</em><em>.</em><em>.</em><em> because </em><em>c</em><em>ar has less </em><em>mass.</em><em>.</em>

<em>3</em><em>.</em><em> the third law of motion state that foreign every</em><em> action there is a opposite reaction</em><em>.</em><em>.</em>

<em>Example</em><em>;</em><em> can you throw a ball on the floor </em><em>.</em><em>.</em><em>.</em><em>the floor </em><em>pushes</em><em> </em><em>back</em><em> that the ball</em><em>.</em><em>.</em>

The process of DNA replication
Molodets [167]

Answer: Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin. Several enzymes and proteins then work together to prepare, or prime, the strands for duplication. Finally, a special enzyme called DNA polymerase organizes the assembly of the new DNA strands. The following description of this three-stage process applies generally to all cells, but specific variations within the process may occur depending on organism and cell type.
