The cell would have to take in and use more energy in order to break the covalent bonds.
The correct option is B
Hydrogen bonds :
are the chemical mechanism that governs the complementarity of the bases of DNA. This correspondence is unique thanks to the geometry of the hydrogen donor atoms and the acceptors that form the bases.
The (hydrophobic) bases are stacked inside the double helix of DNA; their plane is perpendicular to the axis of the double helix. The outside (phosphate and sugar) is hydrophilic.
The hydrogen bonds between the bases of one strand and the bases of the other strand keep the 2 strands united.
One purine on one strand necessarily binds to a pyrimidine on the other strand. As a corollary, the number of purine residues is equal to the number of pyrimidine residues.
* A binds to T (by 2 hydrogen bonds).
* G binds to C (via 3 hydrogen bonds: more stable bond: 5.5 kcal vs 3.5 kcal).
What part of the DNA strand do hydrogen bonds hold together?
hydrogen. Covalent bonds occur within each linear strand and strongly bond the bases, sugars, and phosphate groups (both within each component and between components). Hydrogen bonds occur between the two strands and involve a base from one strand with a base from the second in complementary pairing.

I know the awnser it is c
1.
The answer is clearly "C" because an adaptive feature is a feature in which a living organism has adapted to, for example:
Millions of years ago, fish and other water creatures evolved to breathe on the surface, and not just in the water. However, this process took many years to adapt to the climate.
2.
I know that this is a gene so I assume, by the wording that this is a length of DNA from another human. Can't particularly explain this very clearly though, sorry. You can read more about it here though by searching about it, sorry I can't put the link as my answer will be removed.
I hope this helps you but if it does not, don't be mean! Message me and I will try my hardest to resolve my answer! :D
Hi There!
Question - The survival of some plants depends on their ability to have seeds transported to a favorable environment. Describe three different ways seeds can be transported from one location to another?
Answer/Why - The seeds can be catch the wind and blow to a place to grow. The seeds can be carried by the animals catching them. And seeds can be transported by the water.
Hope This Helps :)
Answer:
The correct answer is option d.
Explanation:
The production of Acetyl-CoA takes place by the dissociation of both carbohydrates and lipids in the process of glycolysis and beta-oxidation. It then moves into the TCA cycle in the mitochondria and combines with oxaloacetate to give rise to citrate.
In the given case, no labeling will be found in the acetyl-CoA. The labeled C3 and C4 carbon of glucose signify the carboxyl carbon of pyruvate. In the succeeding reactions of the transformation of pyruvate to acetyl-CoA, the carboxyl carbon gets lost in the form of carbon dioxide. Thus, acetyl-CoA does not comprise any labeled C3 and C4 of glucose.
