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

The depletion of the Earth's ozone layer allows more harmful ultraviolet (UV) radiation from the sun to reach the Earth's surface, leading to:

• Increased risk of skin cancer and cataracts in humans
• Damage to crops and marine life
• Disruption of ecosystems

Explanation

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

Explanation

• The correct way of writing a scientific name of an organism is in italics, with the genus capitalized and the species in lowercase.
• Therefore, the correct example among the options should be: Houbara bustard.

Explanation

• Tables and graphs are both essential methods for organizing and visualizing data, and they complement each other.

Tables are useful for:

• Displaying precise values and data points
• Organizing large datasets
• Performing calculations and data analysis

Graphs are useful for:

• Visualizing trends and patterns
• Displaying relationships between variables
• Communicating complex data insights effectively

Explanation

• A hypothesis is a proposed explanation for a phenomenon or a problem that can be tested through scientific investigation.
• It is a educated guess that provides a possible answer to a question or problem.
• A hypothesis must be testable and falsifiable, meaning that it can be proven or disproven through experimentation or data collection.

Explanation

• A ratio is a comparison of two values or quantities, often expressed as a fraction or a decimal.
• It shows the relative size or magnitude of one value compared to another.
• For example: 2:3 or 2/3 is a ratio comparing the value 2 to the value 3.
