Explanation

• The high resolution of the electron microscope is primarily due to the short wavelength of the electron beam.
• This shorter wavelength allows for higher resolution and the ability to visualize smaller structures.

Explanation

Biodiversity is impacted by various human activities, including:

• Pollution: Chemical pollutants can alter ecosystems, affecting species development, growth, and survival.
• Deforestation: Habitat destruction and fragmentation lead to population decline, isolation, and extinction.
• Overhunting: Overexploitation of species for food, trophies, or other purposes can deplete populations and drive extinctions.

Explanation

• Fungi have cell walls made of chitin and are all heterotrophic, obtaining nutrients by decomposing organic matter or forming symbiotic relationships.
• This distinguishes them from other kingdoms, making Fungi unique in their combination of cell walls and heterotrophy.

Explanation

• Felis catus is the scientific name for the domestic cat.
• It belongs to the family Felidae and is a member of the order Carnivora.

Explanation

In the five-kingdom system, viruses are not placed in any of the five kingdoms:

1. Monera (bacteria)
2. Protista (eukaryotic organisms)
3. Plantae (plants)
4. Animalia (animals)
5. Fungi (fungi)

Viruses are considered non-living entities.

So, in the five-kingdom system, viruses are not classified in any of the five kingdoms.

Explanation

In the four-kingdom classification, Kingdom Metaphyta (also known as Plantae) includes:

• Angiosperm (flowering plants)
• Gymnosperm (conifers and related plants)
• Bryophyta (mosses)

Algae are classified under Kingdom Protista.

Explanation

In the taxonomic hierarchy, Class is the most inclusive and encompasses all the other terms:

• Class includes multiple Orders
• Order includes multiple Families
• Family includes multiple Genera (plural of Genus)
• Genus includes multiple Species

Explanation

Analogous structures are features that have a similar function but different origins and structures, and are not considered in classification.

Explanation

• The correct sequence of classifying an organism is: Kingdom → Phylum → Class → Order → Family → Genus → Species
• This sequence is known as the taxonomic hierarchy or Linnaean system, developed by Carl Linnaeus.
• It categorizes living things from most general (Kingdom) to most specific (Species).

Explanation

• Amoeba is a protist, not an animal.
• It belongs to the kingdom Protista, not Animalia.
