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

Glaucoma is caused by an increase in pressure within the eyeball, specifically in the fluid pressure inside the eye.

This increased pressure can damage the optic nerve and lead to vision loss if left untreated.

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.

Explanation

• A proportion is an equation that states that two ratios are equal.
• It is often written in the form: a/b = c/d
• Where a, b, c, and d are values or quantities, and the ratio a/b is equal to the ratio c/d.
• For example: 2/4 = 3/6

Explanation

• Quantitative observation involves the use of instruments, tools, or equipment to measure and collect numerical data about the world.
• This approach focuses on quantifying properties, such as length, mass, temperature, or time, to describe phenomena accurately.

Examples of equipment used in quantitative observation include:

• Thermometers
• Spectrophotometers
• Microscopes
• Telescopes
• Stopwatches
• Balances
