<u>Answer:</u>
<em>The star is travelling away from the earth.</em>
<u>Explanation:</u>
<em>A star’s temperature largely determines its color. </em>Stars with higher temperature have a bluish color and stars with low temperature appear red in color. But the color of star that we observe from the earth is different from its actual color.
<em>This variation in color is due to Doppler effect. </em>When the movement of a star is towards the earth the frequency shifts to the higher frequency region and when the movement is away from the earth the frequency of the light emitted will shift to the lower frequency region. <em>Color of light depends on the frequency. </em>
The color corresponding to the <em>lower frequency region</em> is red and color corresponding to <em>high frequency region</em> is blue. <em>So when the star moves away from the earth it appears red in color.</em>
Answer:
i giess its ans is option b
Answer:
least, most
Explanation:
Antimicrobials are substances that function by limiting the activities of microorganisms either by killing them or by inhibiting their growths.
Antimicrobials that exhibit a wide range of cellular targets are least selective of the type of cells they kill or inhibit. They are also said to have a wide spectrum of activities.
On the other hand, antimicrobials that exhibit a narrow range of cellular targets are most selective of the type of cells they kill or inhibit. They are said to have a narrow spectrum of activities.
Answer:
b. heat energy
Explanation:
Water, which is able to exist in three different states moves from one form to another. Water can move from the ocean to the atmosphere via a process called EVAPORATION. During the process of evaporation, the sun plays a major role by supplying the HEAT ENERGY required to change water from its liquid form in the ocean to its gaseous form in the atmosphere.
Water cycle of the earth helps ensure that water is not lost in any of its forms. Liquid water stored in the ocean gets evaporated as a result of heat energy into the atmosphere as water vapour.
