Explanation

A multimeter is mainly used to measure the three basic electrical characteristics of:

voltage,

current,

and resistance. 

A multimeter can be used as an ammeter to measure current, as a voltmeter to measure potential difference

Explanation

The cockroach does not have lungs.

The respiratory system of Cockroaches consists of Tubes, called Tracheae.

The trachea is a dense network of an air tube

Explanation

 Nucleic acids are composed of nucleotides.

NTPs (Nucleoside Triphosphates) are a type of nucleotide.

They consist of a nitrogenous base, a pentose sugar (ribose in RNA or deoxyribose in DNA), and three phosphate groups

Nucleic acids like DNA and RNA are built from chains of these nucleotides. 

Explanation

A centripetal force always acts perpendicular to the direction of an object's motion,

Meaning it doesn't contribute to the object's speed or change in kinetic energy, which is the definition of work. 

Explanation

 The most precious falcons used in falconery are the Saker and the Peregrine falcons.

Explanation

The Born-Haber cycle is used to calculate the lattice energy of an ionic compound,

which is the energy required to form the ionic lattice from its gaseous ions.

Explanation

Longitudinal waves cannot be polarised.

This is because the transverse wave can vibrate in all directions and is perpendicular to the direction of propagation.

Explanation

• the variety of people from one another in terms of color race religion language and region is called diversity
• ***
• Diversity means having a range of people with various racial, ethnic, socioeconomic, and cultural backgrounds and various lifestyles, experiences, and interests.
  
  

Explanation

 Crystals in which lattice points are occupied by metal ions are a) Ionic crystals. 

Ionic crystals are formed by the electrostatic attraction between positively charged metal cations and negatively charged anions.

These ions are arranged in a regular lattice structure. 

Explanation

The enzyme is primarily responsible for unwinding the DNA double helix

During cell division and DNA replication is DNA helicase.

It "unzips" the DNA strands, allowing the strands to be separated and copied.

This unwinding process is crucial for initiating DNA replication.
