Answer:
aspartate, lysine, arginine and asparagine residues
Explanation:
The activity of adenylyl cyclase (adenylate cyclase) is regulated by the conformation changes on the protein sub-units of the quartenary structure of the enzyme. These consist the amino acid groups that make the structure. For instance, the amino acid aspartate, lysine, arginine and asparagine all experience change of some sort. The residues stabilize the transition state of the enzyme. The proteins, while the enzyme carries the catalytic activity, mat become slightly mutated.
<h3>I believe the answer is B but don't hold that on me</h3>
A
Sea floor spreading occurs in divergent boundaries where new crust is being formed
Explanation:
The earth's magnetic field is NOT static. There have been about 4 -5 flips in the last 10 million years. Earth's magnetic field affects the orientation of highly ferromagnetic ions on earth such as iron. These ions align with the earth's magnetic fields. Magma has significant iron content and when it gets to the surface, these ions align with the earth's magnetic fields before the magma cools to solid rock forming bands on the rocks. At divergent boundaries, these bands are evident on the newly formed crust when magma rises to replace the void from the diverging tectonic plates. Some of these bands align in the opposite orientation and provide evidence of when the earth’s magnetic field flipped. Even during magma flow in a volcanic eruption, when the magma, with high iron content, cools, bands on the rocks are evident due to this phenomenon.

Answer:
<h2>A shadow is an area where direct light from a relatively small source is blocked by some opaque object. If the source is genuinely the only light around, the shadow will be absolutely black, and will have no colour.</h2>
