a.) Asp and Lys
Asp will elute first from the column because it has less positively charged functional groups than Lys.
b.) Arg and Met
Met will elute first from the column because it has less positively charged functional groups than Lys.
c.) Glu and Val
Glu will elute first from the column because it has more negativity functional groups than Lys and will be not be much retained by the -SO₃⁻ groups from the ion-exchange coloumn.
d.) Gly and Val
Gly will elute first from the column because Lys have a longer alkyl chain which will be attracted by the strongly hydrophobic backbone for the resin.
e.) Ser and Ala
Ser will be eluted first from the column because Ala alkyl chain will be more attracted by the strongly hydrophobic backbone for the resin. Ser have an -OH group which will decrease the hydrophobicity of the alkyl chain and will not be so much retained on the column.
A. False. If it is high tide in one place on Earth, the place exactly opposite to it will also have a <em>high</em> tide.
The gravitational attraction of the Moon and the inertia of the oceans cause <em>two tidal bulges </em>on opposite sides of the Earth.
B. True. Cassini used flybys of Venus, Earth and Jupiter as slingshots to reach Saturn.
C. True. The whole solar system moves around the galaxy.
D. True. If a planet’s gravity is not strong enough, the molecules in its atmosphere will have enough kinetic energy to escape into space.
E. False. The <em>mass of an object is constant</em>, but its <em>weight changes</em> according to the gravity of the planet.
F. False. To find the mass of an object, <em>divide</em> its weight by gravity.
or weight = mass × gravity
∴ <em>Mass = weight/gravity
</em>
Answer:
Dissolving ice tea mix in water is a chemical change
Explanation:
It is a chemical change because you can not bring back the ice tea mix back if you mix it in water.
Hope it helps
Physical because you can see it evaporate have a great día
