During the moon’s quarter phases, the suns pulls against the moon’s gravitational pull instead of with it. during these tides the result is the lowest high tide and the highest low tide. so basically different gravitational pull as well as depends if its a full moon or not and if the sun, earth and moon as semi aligned
Answer:
Before cell division must occur, the chromosomes must replicate themselves. Sister chromatids are the two initially identical copies.
Sickle cell sickness might've been identified with her passing since her body and cells weren't getting enough oxygen. Indications more often than not don't happen until after the age of 4 months. All individuals with sickle cell iron deficiency have excruciating scenes called emergencies. These can last from hours to days,
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!
