The answer is B: it creates offspring from parents
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.

The answer is 50%.
The-related number of thumps every moment of the heart when working at its greatest that is generally evaluated as 220 short one's age achieved 90 percent of his most extreme heart rate when tried on a treadmill.
It is prescribed that you practice inside 55 to 85 percent of your most extreme heart rate for no less than 20 to 30 minutes to get the best outcomes from oxygen consuming activity. The MHR (generally ascertained as 220 less your age) is the maximum furthest reaches of what your cardiovascular framework can deal with amid physical movement.
Answer:
The sun provides the energy for plants which starts the whole food chain.
Explanation:
The human body has to remain a certain temperature. The sun provides that heat. I have to drink. The sun evaporates water so it can be redistributed in the form of rain. Your life is set by the movement of the sun.
