Explanation

Secretin is a hormone released from the small intestine that stimulates the liver (hepatic) and pancreas to secrete bile and bicarbonate-rich fluids.

It helps neutralize stomach acid in the duodenum for proper digestion.

Explanation

Thomas Young demonstrated the wave nature of light through his famous double-slit experiment.

This experiment showed interference patterns, confirming light behaves as a wave.

Explanation

The else keyword is used to provide an alternative block of code if the if condition is false.

It works with if to handle two different choices in decision-making.

Explanation

Acetic acid is commonly produced through the fermentation of ethanol by Acetobacter bacteria.

This biological process is widely used in making vinegar, which contains acetic acid.

Explanation

According to Einstein’s equation E = mc², where c = 3 × 10⁸ m/s (speed of light),

E = 1 × (3 × 10⁸)² = 9 × 10¹⁶ joules.

This shows that 1 kg of mass can be converted into 9 × 10¹⁶ joules of energy.

Explanation

A co-enzyme is a non-protein organic molecule that is loosely bound to the enzyme and helps in its activity.

It often acts as a carrier of electrons or functional groups (e.g., NAD⁺, FAD).

Explanation

The exchange of parts of non-sister chromatids of homologous chromosomes during meiosis is called Crossing over. 

During meiosis, homologous chromosomes pair up and "cross over," exchanging genetic material between their non-sister chromatids, resulting in new combinations of alleles. 

Explanation

The force of attraction between helium atoms is the London dispersion force. 

Helium is a non-polar noble gas, so the only force of attraction between its atoms is the weak London dispersion force, which arises from temporary fluctuations in electron distribution. 

Explanation

 The direction of a vector in space is typically specified by three angles.

These angles, often referred to as azimuth, elevation, and tilt (or polar/inclination), describe the vector's orientation in 3D space relative to a chosen reference frame. 

Explanation

The rate of E1 reactions depend only on the concentration of the substrate.
