Explanation

 The cytoskeleton is a network of protein fibers that runs throughout the cytoplasm of a cell.

It provides structural support, maintains cell shape, and is involved in various cellular processes like movement and organelle positioning. 

Explanation

A basic buffer is made by combining a weak base with its salt formed with a strong acid (e.g., NH₄OH + NH₄Cl).

This mixture resists pH change upon addition of small amounts of acid or base.

Explanation

The peptidoglycan cell wall is a unique and defining feature of bacteria.

It provides structural support and protection, helping bacteria maintain their shape.

Peptidoglycan is not found in amoeba, protozoa, or viruses, as these organisms have different structural components.

Explanation

The rare site of infection in the urinary tract is the Ureter. 

While UTIs most commonly affect the bladder and urethra (lower urinary tract), the ureters (tubes carrying urine from kidneys to bladder) can also be infected, though it's less common.

The kidneys are the least common site of infection in the urinary tract, and are considered a serious complication. 

Explanation

 The hormone that is not secreted by the anterior pituitary gland is Oxytocin. 

Oxytocin is secreted by the posterior pituitary gland, while the anterior pituitary secretes hormones

Like growth hormone, follicle-stimulating hormone, and adrenocorticotropic hormone

Explanation

In a transistor, the emitter-base junction is forward-biased. 

For a transistor to function properly as an amplifier, the emitter-base junction needs to be forward-biased, allowing current to flow from the emitter to the base. 

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 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

• Communication satellites are used for telecommunication.
• Including telephone communication, internet connectivity, and television broadcasting, enabling global communication networks.
