Do you think partial melting will occur if there is direct contact of hot molten rock in the Earth’s crust?
Answer:
As it moves toward the surface, and especially when it moves from the mantle into the lower crust, the hot magma interacts with the surrounding rock. This typically leads to partial melting of the surrounding rock because most such magmas are hotter than the melting temperature of crustal rock.

just got done with the test
Insulin lowers the blood-sugar levels in the body.
What are the functions of insulin?Insulin is a peptide hormone produced by beta cells of the pancreatic islets encoded in humans by the INS gene. It is considered to be the main anabolic hormone of the body.
After you eat, carbohydrates break down into glucose, a sugar that is the body's primary source of energy. Glucose then enters the bloodstream. The pancreas responds by producing insulin, which allows glucose to enter the body's cells to provide energy.
Insulin is a peptide hormone secreted by the β cells of the pancreatic islets of Langerhans and maintains normal blood glucose levels by facilitating cellular glucose uptake, regulating carbohydrate, lipid and protein metabolism.

They are formed by the accumulation of precipitation, such as rain or snow, in a specific area and flow in a defined channel towards an ocean, a lake, or another river. Rivers can vary greatly in size and length, with some being just a few meters wide and a few kilometers long, while others can be several kilometers wide and thousands of kilometers long.
They are an important resource for humans and other living organisms, providing water for irrigation, drinking, and industrial uses, as well as serving as habitats for a wide variety of plant and animal life. Rivers also shape the land they flow through, eroding and depositing sediment, and creating features such as valleys, deltas and canyons.
