Explanation: I suggest: A freeze occurs when the temperature drops below 32 degrees, and frost can happen when the air temperature (which is measured about six feet above the ground) is up to about 36 degrees. If part of your yard is lower than the rest, it’ll probably be coldest there since cold air is heavier and sinks down.
Light from the galaxies is shifted to longer (and thus redder) wavelengths - it is 'red-shifted.' As the objects in space that are moving away from Earth exhibit redshift, and objects in space that are moving toward Earth exhibit blueshift, most galaxies in the universe exhibit redshift, i.e., option D.
<h3>What are redshift galaxies?</h3>
Most other galaxies are moving away from others since 1929, when Edwin Hubble discovered that the Universe is expanding. Light from these galaxies is shifted to longer (and thus redder) wavelengths - it is 'red-shifted.'
Redshift is the displacement of an astronomical object's spectrum toward longer (red) wavelengths. It is attributed to the Doppler effect, which is a change in wavelength caused by the motion of a given source of waves and an observer with respect to each other.
As objects in space that are moving away from Earth exhibit redshift, and objects in space that are moving toward Earth exhibit blueshift. It shows that most galaxies in the universe exhibit redshift.
Thus the correct option is D.

1. Jesi is on vacation and visited a seafood restaurant to eat a shrimp dinner. About thirty minutes after eating, she begins to feel ill and her stomach is rumbling. Shortly after, she begins to vomit. Jesi's body is experiencing a reaction to an ________ stimulus.
internal response
2. During a stressful or threatening situation, which of the following is the best description of how the nervous systems in your body would respond?
The parasympathetic nervous system senses the danger and the sympathetic nervous system responds by releasing adrenaline.
3. Which of the following scenarios is the best example of positive feedback?
As blood pressure decreases, your heart rate increases.
B. Mitochondria
The mitochondria is where ATP is made, hence why it is often called the "powerhouse" of the cell.
