Answer:
The reason why stars are so important is because they have helped humans navigate through Earth . When it was dark these stars would light up the sky giving people light . ... the most important is the Sun, because without that it wouldn't be life on Earth . Earth would just be a rock with ice.

<em>DNA </em><em>can </em><em>be </em><em>used</em><em> </em><em>to </em><em>tell </em><em>people</em><em> </em><em>apart </em><em>because</em><em> </em><em>humans </em><em>differ </em><em>from </em><em>each</em><em> </em><em>other</em><em> </em><em>based </em><em>on </em><em>either</em><em> </em><em>their</em><em> </em><em>DNA </em><em>sequences</em><em> </em><em>or </em><em>the </em><em>lengths </em><em>of </em><em>repeated</em><em> </em><em>regions </em><em>of </em><em>DNA.</em><em> </em><em>Length</em><em> </em><em>difference</em><em> </em><em>are </em><em>typically</em><em> </em><em>used </em><em>in </em><em>forensics </em><em>and </em><em>paternity </em><em>testing</em><em>.</em>
A mutation which occurs when a base is introduced into the DNA sequence before transcription begins will lead to frame-shift of a single base on the DNA sequence resulting in nonfunctional protein from the transcribed mRNA.
Explanation:
This change either through addition or deletion of a single base in the codon sequences of the DNA will modify the amino acid codes and will result in nonfunctional proteins after transcription.
This mutation will just result in change of a single base, i.e., it would be added either to the enhancer region or the silencer region of the sequence before the promoter which initiates transcription.
The mRNA produced due to mutated DNA sequence after the deletion or insertion point will be read as out of frame thus resulting in nonsense protein.
Answer:
No atoms are created or destroyed in chemical reactions.
Explanation:
Matter cannot be created or destroyed. When two reactants contact each other, a chemical reaction occurs which breaks the bonds between atoms and rearranges them, forming new bonds which transform them into the product. The same amount of atoms exists before and after the reaction.
