Reactions that hydrolyze the phosphodiester bonds split the DNA molecule between the phosphate groups and the hydroxyl groups of the two sugar groups.
In DNA there is a covalent bond through a phosphate group that connects the hydroxyl group (OH) at the 5' position of the pentose sugar and the hydroxyl group at the 3' position of the pentose sugar of the next nucleotide. This covalent bond is called a phosphodiester bond because chemically the phosphate group is in the diester form.
In other words, the phosphodiester bond connects the sugar in one nucleotide to the sugar in the next nucleotide, so this bond simultaneously connects the two consecutive nucleotides to form a polynucleotide chain. If there is an enzyme that catalyzes the hydrolysis of covalent bonds that combine nucleotides, what happens is that the phosphodiester link between deoxyribose sugars will break.

Answer:
The rate of photosynthesis was more than the rate of respiration
Explanation:
Photosynthesis has to do with the synthesis of sugar molecules from inorganic products such as water and carbon dioxide. Respiration on the other hand has to do with breaking down of the sugar molecule from photosynthesis to release the energy locked up in the sugar for various metabolic processes in the plant's body.
<em>If both processes are balanced, there will be no net sugar production. Hence, if an excess of sugar produced fossil fuels, it thus means that there was net production of sugar in the past. The rate of photosynthesis was more than the rate of respiration in the past.</em>
For the first question the answer is C. We know this because Dalton considered matter to be composed of very tiny indivisible particles called atoms which means it can't be further subdivided and thus no sub-atomic particles. And for the second question the answer is the Last one: <span>Ernest Rutherford. The rest of them did not give evidence of the existence of a nucleus or gave poor evidence. Hope this helps</span>
Explanation:
A cryosphere is just a hydrosphere but it's frozen in some way. glaciers, ice caps, and icebergs are cryospheres (frozen bodies of water).
Animals that live in any snowbound region may adapt to its environment by growing bigger feet in order to be able to walk over the deep snow. Also the animals might grow thicker fur in order to keep the animal warm while in the cold weather.
