It takes the Earth (approximately) 364.25 days to revolve around the sun. That's why we have leap days.
Hope that helps!
Answer:
Diffusion.
Explanation:
According to the information given before the example in the question and considering the fact that the bag was secured on both ends before being placed in the solution, provided that there were no holes on the surface of the bag, the iodine solution could have diffused through the bag into the starch solution hence the color change to black after 30 minutes.
I hope this answer helps.

Answer:
It is (x+y)t miles from the school to Bob's home
Explanation:
Assuming the distance from Bob's home to school is d miles and the time taken is t hours
Distance covered when he had flat tire = d/2, time taken = t/2, rate = x miles/hour
Rate = d/t
x = (d/2)/(t/2)
d = xt miles from Bob's home to halfway the school
distance from halfway the school to the school = d/2, time taken = t/2, rate = y miles/hour
rate = d/t
y = (d/2)/(t/2)
d = yt miles
Total distance from school to Bob's home = xt + yt = (x + y)t miles
You did not include the diagram, but the answer is very easy to figure out. The mRNA base that will go in location 1 depends on the DNA base in location 1:
If the DNA base is Adenine (A), the mRNA base will be Uracil (U)
If the DNA base is Thymine (T), the mRNA base will be Adenine (A)
If the DNA base is Cytosine (C), the mRNA base will be Guanine (G)
If the DNA base is Guanine in (G), the mRNA base will be Cytosine (C)
