Más agua salada
Al analizar la superficie del planeta, sencillamente se puede estimar que un 71 % está cubierto de agua, y el restante 29 % es masa continental. Ahora bien, la superficie no equivale a la masa, por lo tanto no podemos afirmar que la Tierra sea un 71 % de agua y el resto de tierra. Debemos ser un poco más específicos.
Answer:
75%
Explanation:
3/4 of the table have at least one capital B in it, which means it's the dominant trait. This will show up over the recessive trait (b), so this means 3/4 of the offspring will have brown eyes, or 75%. Hope this helps!
Answer:
<em> e) Ala</em>
Explanation:
Alpha helix is a secondary structure of proteins, it is made of 3.6 aminoacids residues per turn, this structure is possible thanks to local hydrogen bonding between C=O and N-h groups. The result is a cylindrical structure with a hydrogen-bonded backbone and the outside studded with side chains.
Glycin has an -H in its side chain, this makes it a too flexible molecule, therefore it's unusual to find them in alpha-helical structures because their presence could cause the helix to deform. Large R-groups can also affect this stability, phenylalanine has a bulky aromatic side group, this discards it as a stabilizer. Serine has a hydrogen bond donor or acceptor as a side chain, due to the proximity to the main chain it competes with the main chain to form NH and CO bonds. Alanine is the most common amino acid in alpha-helix structures because it has a short and no charged R group (unlike arginine that even when it's short it has a charged R-group), this makes it flexible enough to keep the structure stabilized.
Hope you find this information useful! good luck!
