Explanation

• Enzymes sometimes need a non-protein component to function properly.
• This non-protein part is called a cofactor.
• If it is loosely attached, it can easily separate from the enzyme.
• Cofactors help enzymes carry out biochemical reactions.
• They may be inorganic ions or organic molecules.

Explanation

• Light Year is the distance that light can travel in one year.
• The distance light travels in one year is known as light year.
• 1 light year is equal to 9.5 x 10¹²km.

Explanation

• Oomycetes are fungus-like organisms, often called water molds.
• Although they resemble true fungi, their cell wall composition is different.
• In oomycetes, the cell wall is mainly composed of cellulose.

Additional information:

• True fungi have chitin in their cell walls, while oomycetes have cellulose.
• A common example of oomycetes is Phytophthora, which causes plant diseases.

Explanation

Red light rays have the lowest frequency and highest wavelength value.

Blue or violet light has the shortest wavelength.

Explanation

Velocity is a vector quantity. 

A vector quantity has both magnitude and direction.

Velocity, which describes the rate of change of position in a specific direction, needs both a magnitude (speed) and a direction to be fully defined. 

Vector Quantities: Velocity, momentum, torque, acceleration.

Scalar Quantities: Work, distance, speed, mass.

Explanation

Most proteins are made up of 20 different amino acids.

These 20 amino acids are commonly referred to as the standard or proteinogenic amino acids.

While other amino acids exist, they are not typically found in the primary structure of proteins that make up most living organisms.

Explanation

According to Coulomb’s Law, force is inversely proportional to the square of distance: F∝ 1/r².

So, if distance is doubled, force becomes 1/(2)² = 1/2.

Explanation

Real gases show deviation from ideal behavior at low temperature and high pressure.

Due to increased intermolecular forces and reduced volume available for gas molecules, which contradicts the assumptions of ideal gas behavior.

Explanation

Electric flux (Φ) is maximum when E and A are parallel, i.e., angle = 0°.

Formula: Φ = E·A·cosθ → cos(0°) = 1 gives maximum flux.

Explanation

According to the periodic trends, Nitrogen (N) has the largest ionization energy among the given atoms: N, P, As, and Sb. 

 Ionization energy generally increases from left to right across a period on the periodic table.

Since Nitrogen is to the left of Phosphorus, Arsenic, and Antimony, it will have the highest ionization energy.

Additionally, within a group, ionization energy decreases down the column.
