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.

Answer:
Explanation:
ATP can be described as the unit for energy. Cellular processes that can involve ATP/energy are
1) Respiration: This involves the cells obtaining ATP by means of combining oxygen and glucose.
2) Metabolism: This is the building up (anabolism) and breakdown down (catabolism) process. Generally, anabolism requires ATP while catabolism releases ATP.
3) Active transport: This requires ATP to move substances or molecules across the cell membrane from a region of lower concentration to a region of higher concentration.
4) DNA replication: ATP is required to sustain replication of DNA at the replication fork during.
5) processes in the cell cycle: ATP is required for the S phase and the mitotic phase of the cell cycle.
6) Ion transport: Ion transport also requires the use of ATP to transport ions across the membrane of cells
Oceanic crust has been forming on Earth for over 4 billion years, all of the sea floor older than <span>about 200 million years. </span>
True
because ur hart pumps faster and then blood flow increases and the you have more blood delivery to your body
Explanation:
Proteins and nucleic acids play important biological functions : they catalyze and regulate reactions, transport substrates, code and transcribe genetic information. It is widely appreciated that water molecules play an invaluable role in governing the structure, stability, dynamic, and function of these biomolecules
Water, without any doubt, must be considered an integral part of biological macromolecules. The living world should be thought of as an equal partnership between proteins, nucleic acids and water
