BECAUSE these bases are bound to each other through 3 hydrogen bonds. where the A is bound with T through only 2 H-bonds. for this reason the GC pairing is stronger than AT pairing.
Many things are harder than stainless steel. Stainless steel can vary in hardness depending on the alloy and any treatment(s), but lots of carbon steels can be harder. Certainly diamond is harder as it is the hardest substance known to man.
because the oceans hold lots of heat
C and G are harder to separate than A and T because 3 hydrogen bonds exist between the bases C and G while only 2 hydrogen bonds exist between A and T.
The dumbbell press can be harder than the barbell press because it requires more stabilization and coordination to lift two separate weights instead of one barbell.
because they need more codes and they are harder to guess/infringe as the person who created the password may have more than 1 word in their and may include lots of numbers :)
Some mixtures can be easily separated and some mixtures can't be easily separated.
no, teeth are harder than rocks
No. Diamond is harder than emerald.
If you are talking the NGK Iridium plug, lots of offroaders use them. Its probably because offroaders work harder and therefore run a lot hotter than road bikes and need a harder, hotter than normal plug
Harder Than the Best was created in 1979.
Tungsten is a metal that is harder than steel.
To work harder than your hardest involves you pushing yourself to the limit, working harder than you ever have before.
