a. What is a star's spectrum?

A star's spectrum refers to the <em>"amount of light"</em> that stars they give off according to varying wavelengths. Since we cannot tell the amount of light a star gives off quantitatively from Earth, we can differentiate them according to how bright they appear.

b. Which spectrum is most common in stars?

Stars are classified according to their spectra <em>(elements in the star)</em>. They are classified into 7 types <em>(O, B, A, F, G, K and O). </em>The most common type is M, however, it gives off a dim light.

c. How can it differ from start to star?

Although stars follow a continuous spectrum, the spectra of a star differs from each other because <u>they do not give off the same amount of energy at the different wavelengths. </u>

d. What does the spectrum tell us about the star?

The spectrum can tell the<em> surface temperature</em> of the star. This means that a blue star (we often see it as a white-colored star from Earth) is hotter than that of a yellow star. A red star is considered the coolest star among all.

The spectrum of stars also allows the astronomers to study composition of the stars according to their <em>wavelengths.</em>

Why must cells be able to both transcribe and replicate their DNA? (2 points)
Artemon [7]

Answer: The correct answer is D) Replication creates new DNA while transcription creates mRNA.

Transcription is a process, which includes copying of the genetic formation from DNA into mRNA ( messenger RNA). This provides instructions for the synthesis of specific proteins.

Thus, the correct option is D)
