!!!!HELP!!!! BEST ANSWER GETS BRAINLIEST!!!!!The phases of the moon are caused by
A) the moon revolving around the sun and Earth.
B) Earth revolving around the sun and the sun's light being reflect off the moon.
C) the moon revolving around Earth and the moon reflecting sunlight towards Earth.
D) the moon revolving around Earth with sunlight reflecting off of Earth towards the moon.
B) Earth revolving around the sun and the sun's light being reflected off the moon because the moon orbits earth and earth orbits the sun so the sun lights the moon

If a star is 300 light-years from Earth, how long does it take light from that star to reach Earth? 300 light-years 300 years 300 hours 300 days
If a star is 300 light-years from Earth, it will take 300 light years from that star to reach Earth. So, the correct option is A.
What is Light year?
A light year is defined as the larger unit of length used to express astronomical distances which is approximately equal to 9.46 trillion kilometers or 5.88 trillion miles.
A light year is explained as a measure of distance and not as time where light travels at a speed of 300,000 km/s where the distance that light will travel in one year is considered as a light year which is 9.4611012 is equal to km. When a star is 300 light-years from Earth, it will take 300 light years from that star to reach Earth.
Your question is incomplete, most probably the complete question is:
If a star is 300 light years away from Earth, how long does it take light from that star to reach Earth?
A. 300 light-years
B. 300 years
C. 300 hours
D. 300 days
It would take 300 light years to reach Earth.

The Polymerase Chain Reaction (PCR) primers are short nucleotide sequences (composed of approximately 20 nucleotides in size) flanking a target sequence that is amplified during PCR reaction. These primers bind to the DNA template by means of complementary base pairing in order to make billions of copies of a target DNA region, which is then visualized as a band by electrophoresis. In this case, PCR primers from the item a- (i.e., AGCTAAGGCCTTTCGA and CCACGGGTACCTATAA) will bind to the DNA template of lines 1 and 2 in order to amplify a continuous region:
The Foward primer AGCTAAGGCCTTTCGA binds by complementary base pairing:
