Explanation

The pancreas is a unique organ that functions as both an exocrine and endocrine gland.

The exocrine portion produces digestive enzymes that are released into the duodenum through ducts.

The endocrine portion, called the islets of Langerhans, produces hormones like insulin and glucagon, which are released directly into the bloodstream to regulate blood sugar levels. 

Explanation

Stoichiometry calculations can only be carried out when all of the above are true:

Irreversible reactions:

Stoichiometry calculations are based on the assumption that the reaction proceeds to completion, meaning all reactants are used up to form products. 

No side reactions:

Side reactions would introduce additional products and complicate the calculations. 

At least one reactant consumed completely:

Stoichiometry calculations determine the amount of products formed based on the amount of a limiting reactant. 

Explanation

 The magnetic effect of electric current is the principle behind the operation of devices like motors.

When a current flows through a wire, it creates a magnetic field around it. In a motor, this magnetic field interacts with permanent magnets to cause a coil to rotate

This rotation then drives the motor. Electric fans utilize this principle to spin their blades. 

Explanation

 When a stem is cut, water and nutrients may ooze out due to root pressure, a positive pressure in the xylem generated by water absorption in roots.

Explanation

The enzyme responsible for breaking down starch into maltose in the human digestive system is amylase. 

Amylase is an enzyme produced in the saliva and pancreas that specifically breaks down starch into smaller sugar molecules like maltose

Explanation

The ball will fall behind him.

When the man throws the ball vertically upward, it maintains the horizontal velocity of the train due to inertia.

However, the train continues to move forward while the ball is in the air.

As the ball falls back down, it will have traveled a shorter horizontal distance compared to the train,

Resulting in it landing behind the man where he originally threw it. 

Explanation

Conidia are asexual spores produced by fungi.

They are formed on specialized structures called conidiophores

They are often found at the tip of hyphae (the filamentous structures that make up the fungal body). 

Explanation

Newton formulated the laws of motion 

In 1686, he presented his three laws of motion in the “Principia Mathematica Philosophiae Naturalis

Newton's three laws of motion are:

• the Law of Inertia,
• the Law of Mass and Acceleration,
• the Third Law of Motion
