Biology

Iteru [2.4K]2 years ago

 First off, the jaw itself, is capable of projecting an impressive 30% of the total head length, which is over 10% more than the jaw protrusion of a lemon shark.  Also note the teeth of <span>Squalus acanthias </span>actually interlock to form an almost uniform cutting surface. Finally on either side of the jaw you have what is referred to as labial cartilage. These structures fold out as the dogfish projects its jaw, essentially causing the jaw to take on a tubular shape, which increases suction pressure as the shark opens its mouth.  As the jaws close these cartilages snap back into place in folds along the side of the jaw, which is why spiny dogfish, smooth dogs, nurse sharks, and other sharks that make use of this mechanism have such distinctive “cheeks.” The disadvantage it has is that it cannot open its mouth too much.

<span>I think the pKa for acetic acid is about 4.74. Therefore Acetic acid/acetate buffer will work best at 4.74 +/- 1 pH unit and so the pH 8 is far removed from that. Hence it would not buffer at that pH at all.</span>

The best way to measure an exact volume is with a(n) _____________.
xxTIMURxx [149]
The answer is E, graduated cylinder.

Meanwhile beaker and test tubes may have markings, but they're not as accurate. Especially in beakers, their wide diameter only makes an approximate volume, as it is very likely to have a reading mistake on that. Their main function is not to measure volumes, thus there marking may already have an mistake.

And in watch glass and evaporating dish, they're both very shallow and wide in diameter too, so they're not for measuring volumes. Plus, not all of them have markings.

And in graduated cylinder, the thin shape makes the reading a lot more accurate and the main purpose for that is to measure volumes. They also come in transparent tubes that can make the reading clear and easy to read.
