Answer:

Deposition

Explanation:

Landslides occur under the effect of gravity. When a mass of rock or earth slides down from a mountain or from a cliff then this phenomenon is termed as Landslide.

Landslides are considered to be a rapid method of erosion.  Wind, waves, running water, glaciers and gravity are the five agents of erosion out of which the gravity influences the process of Landslides.

Landslides occur suddenly and are dangerous example of the movement of earth materials under the influence of gravity. When weathered material falls away from a cliff, it slides down under the effect of gravity and finally after reaching the hill, the material gets deposited there. This is called Deposition by landslides.

Which of the following statements best describes the role of adenylyl cyclase in the epinephrine signaling pathway?
Nesterboy [21]

Answer:

It accelerates the production of a second messenger.

Explanation:

Adenylyl cyclase is an enzyme capable of converting ATP molecules into cyclic adenosine monophosphate AMP (cAMP). The cAMP molecule is considered to be a second messenger that transfers the hormonal signal (i.e., epinephrine) inside the cell. Subsequently, cAMP activates molecular signaling events by binding and thus activating cAMP-dependent protein kinase A (PKA). Finally, this last protein (PKA) phosphorylates different proteins that control many diverse cellular processes.
