<h2>Answer:</h2>
Correct order from least greatest mass to greatest mass:
- Terrestrial
- ice giants
- Ice dwarfs
- Gas giants
<h3>Explanation:</h3>
The above given list contains the names of different planets depending upon their compositional characteristics. According to this list gas giants are heavier and then ice dwarfs and then ice giants.
Terrestrial which means planet earth is top on the list, which is lighter in weight than other planets.

Answer:
XbY
Explanation:
The gene responsible for colorblindness is written as Xb since it is present on the X chromosome. In humans, sons get their X chromosomes from the mother while inheriting the Y chromosome from the father. In the given cross, the genotype of the colorblind mother would be XbXb (the X-linked recessive traits such as colorblindness are expressed in homozygous conditions in females).
She would transmit one copy of "Xb" to her son. The genotype of the father would be "XY" and he will give "Y chromosome" to the son. Therefore, the genotype of the son would be "XbY".
The correct answer is: In DNA and RNA, a phosphodiester linkage connects the 3' carbon of one nucleotide and the 5' carbon of another.
The phosphate of one nucleotide is covalently bound to the sugar of the next nucleotide in DNA molecule (or hydroxyl groups in phosphoric acid react with hydroxyl groups on 3' carbon atom of one sugar molecule (deoxyribose) and the 5' carbon atom of another sugar molecule (deoxyribose) to form two ester bonds). In RNA molecule linkage is between the 3' carbon atom of one sugar molecule (ribose) and the 5' carbon atom of another, (ribose).
Hydrolysis of phosphodiester bonds is catalyzed by the action of enzymes phosphodiesterases.
