a. True.
There are 3 main types of blood vessels.
Arteries that take blood away from the heart. Veins that carry blood from capillaries back to the heart. Capillaries which are responsible for the exchange of materials between blood and other tissues.

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.
