The answer is c because many things are losing their habitat and food sources
Answer:
No.. I think they are made up of nucleotides
Explanation:
It will stay the same.
The mass isn't <em>going anywhere</em> (You did mention the jar was hypothetically and therefore hermetically sealed)
The only thing changing here is the density of the water in the jar (whether it be vapor, liquid or otherwise)
as the temperature drops and the vapour becomes liquid, the water will be more dense.
that's not saying that the weight won't increase as that is controlled by the force gravity exerts on the mass. (Hint: water is much more affected by gravity than air is)
The heart,lungs and brain begin to form during the embryonic period of prenatal development.
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.
