Explanation

nsulin is produced by the pancreas, which is an organ located behind the stomach.

The pancreas contains clusters of cells called the Islets of Langerhans, specifically the beta cells within these islets, which are responsible for producing insulin.

Insulin plays a crucial role in regulating blood sugar levels by facilitating the uptake of glucose into cells for energy production or storage.

When blood sugar levels rise after a meal, the pancreas releases insulin to help lower blood sugar levels by promoting the uptake of glucose into cells.

Explanation

Abscisic acid is a plant hormone that regulates processes like dormancy and stomatal closure.

It helps plants respond to stress conditions like drought.

Explanation

Adrenaline (also known as epinephrine) increases the following effects on the heart:

Heart Rate:

Adrenaline increases the heart rate (positive chronotropic effect).

Contractility:

It increases the force of heart muscle contractions (positive inotropic effect).

Conduction Velocity:

It enhances the speed of electrical conduction through the heart (positive dromotropic effect).

Cardiac Output: 

Due to the increased heart rate and contractility, adrenaline boosts the overall cardiac output.

Explanation

Auxin is an unusual plant hormone and the only one to exist as a hydrocarbon gas.

It plays a key role in regulating plant growth and development.
