Answer:
<em>The correct option is D) It does nothing to protect the atmosphere over Antarctica.</em>
Explanation:
On December 1, 1959, the Antarctic Treaty was signed in Washington. According to this treaty, Antarctica was to be used for peaceful purposes. This treaty regulates international relations with the Antarctica region. Freedom to different scientists for research in this area was given through this treaty.
However, the treaty did not discuss anything related to the protection of the atmosphere around Antarctica. Hence, option D can be considered to be a limitation of the Antarctic Treaty System.
It all depends on the trait. If the dominant is more common that the recessive trait then it is more likely to a dominant trait in the gene pool. But if the recessive trait is more common in the gene pool then you will have a recessive trait. Does this make sense? Let me know if I'm right!
Answer:
This movement is called plate motion, or tectonic shift
Explanation:
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>
