Answer:

Muscarine binding to a G protein-coupled receptor results in the activation of the amplifier enzyme adenylate cyclase, and formation of cAMP.

Explanation:

Because I thought the mechanism by which the muscarinic receptor inhibits adenylyl cyclase is through activation of an inhibitory GTP-binding protein, Gi. The α subunit of Gi competes with the α subunit of the G protein activated by stimulatory agonists (GS) for regulation of adenylyl cyclase.

How does altitude affect climate patterns in a region? Areas at high elevations have cooler temperatures. Air continues to warm
Vaselesa [24]

Answer:

A. Areas at high elevations have cooler temperatures.

Explanation:

Areas with high altitude or elevations have cooler temperatures because <u>air molecules are less in the air at high elevation that decreases the gas pressure leading to low temperature.</u>

Earth's surface absorbs heat and diffuses it into the atmosphere that warms up the earth's surface. Layers of the atmosphere in higher-altitude areas diffuses less heat and maintain the low temperature.

Hence, the correct option is "A. Areas at high elevations have cooler temperatures."
