Explanation

The Line Transect Method is a survey technique where an observer follows a fixed pathway (transect) and records bird sightings along the way.

This method is useful for estimating bird populations, species distribution, and habitat preferences.

Explanation

 Yellow fever → Spread by Aedes mosquitoes.

Dengue fever → Spread by Aedes aegypti mosquitoes.

Malaria → Spread by Anopheles mosquitoes.

Viral fever → Caused by different viruses but is not vector-borne; it spreads through direct contact, droplets, or contaminated surfaces

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

most protists qualify as microbes.

The protists are a diverse group of eukaryotes that cannot be classified as animals, plants, or fungi

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

Topology is a branch of mathematics that studies the properties of space that are preserved under continuous transformations like stretching and bending, without tearing or gluing.

It focuses on concepts such as continuity, compactness, and connectedness.

Explanation

 The major effect of habitat fragmentation is Inbreeding & loss of genetic diversity,

As it leads to reduced gene flow and increased isolation of populations

Ultimately decreasing the genetic diversity and increasing the risk of inbreeding

Explanation

Aluminum (Al) reacts with oxygen to form a thin protective oxide layer (Al₂O₃) that prevents further oxidation.

This is why it doesn’t react aggressively with oxygen after this initial reaction.
