Proteins are made by ribosomes and then folded into their correct shape inside the endoplasmic reticulum. These proteins are then taken to the Golgi apparatus, or body, to be modified and then placed into little sacs called vesicles to transport the proteins. The two organelles are related in how they are both involved in the assembly and transportation of proteins.
Answer:Enrico must multiply the distance of mars from sun (meters) with the
to convert the distance in astronomical units.
Explanation:
1 astronomical unit = 

Let the distance between the sun and Mars be Y( meters)
Distance in AU= 
Enrico must multiply the distance of mars from sun (meters) with the
to convert the distance in astronomical units.
Let's use process of elimination to answer this question!
D is wrong, and we know this because of the names of DNA and RNA. The D in DNA stands for deoxyribose, and the R in RNA stands for ribose. These are the types of sugars in each nucleic acid. Therefore, they don't both contain a ribose sugar.
C is wrong, and this is because RNA does not contain thymine, but uracil instead.
B is wrong, and we know this because we know that RNA is composed of only one strand, and therefore it is not composed of multiple stands (plural).
Therefore, A must be right. We can confirm this, because we know that polymers are large molecules consisting of repeated subunits. DNA and RNA are both polymers consisting of nucleotides.<span />
