A star appears to be red in the night sky. Is the star traveling toward the earth or away from the earth? How do we know this? (
neonofarm [45]

<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>

Question 15 (1 point) Which of the following demonstrates positive phototropism? bean plants twisting around a bean pole 12 a ho
Pavlova-9 [17]

Given what we know, we can confirm that among the options listed, the more appropriate example of positive phototropism is the <u><em>houseplant </em></u><u><em>growing towards the </em></u><u><em>window</em></u><u><em>. </em></u>

<h3>What is positive phototropism?</h3>
  • This is a photosensitive reaction that occurs in plants.
  • Positive phototropism is described as the growth of plants towards the source of light.
  • While negative phototropism is when the plants lean away from the light.
  • Sunflowers and bananas, which lean towards the sun as they grow, are prime examples of positive phototropism.

Therefore, given the definition of positive phototropism as the growth of an organism towards a source of light, we can confirm that the option stating that the <u><em>houseplant </em></u><u><em>grows towards the window</em></u> is the best example of this concept, given that the window is the source of light for the plant.
