Solution
Which of the following has the greatest influence on the distribution of animals in marine and fresh water habitats?
A
pH
B
Salinity
C
Water current
D
Turbidity
medium Difficulty
Verified Correct Answer: Option B
Biological Concept & Syllabus Guide
While pH is a crucial factor influencing aquatic life, it's not necessarily the greatest influence on the distribution of animals in both marine and freshwater habitats, as factors like salinity, temperature, oxygen levels, and food availability mostly play significant roles.

Solution
The mineral nutrient that is most bound to the soil is
A
phosphorus
B
calcium
C
iron
D
potassium
medium Difficulty
Verified Correct Answer: Option A
Biological Concept & Syllabus Guide
Phosphorus (P) is generally considered the mineral nutrient most strongly bound to the soil. While other nutrients like nitrogen (N) and potassium (K) are also crucial for plant growth, phosphorus tends to be retained more tightly in the soil due to its interactions with soil particles and its tendency to form insoluble compounds.

Dead plants and animals are decomposed by bacteria and fungi into
A
nitrate
B
nitrites
C

D
ammonium
medium Difficulty
Verified Correct Answer: Option D
Biological Concept & Syllabus Guide
When a plant or animal dies or an animal expels waste, the initial form of nitrogen is organic. Bacteria or fungi convert the organic nitrogen within the remains back into ammonium \(NH^{+}_{4}\), a process called ammonification.

Fractions, Decimals, Percentages & Approximations
Solution
Simplify \(\frac{x^2 - y^2}{2x^2 + xy - y^2}\)
A
\(\frac{x + y}{2x + y}\)
B
\(\frac{x + y}{2x - y}\)
C
\(\frac{x - y}{2x - y}\)
D
\(\frac{x - y}{2x + y}\)
medium Difficulty
Verified Correct Answer: Option C
Step-by-Step Mathematical Solution
\(\frac{x^{2} - y^{2}}{2x^{2} + xy - y^{2}}\)
\(2x^{2} + xy - y^{2} = 2x^{2} - xy + 2xy - y^{2}\)
= \(x(2x - y) + y(2x - y) \)
= \((x + y)(2x - y)\)
\(\frac{x^{2} - y^{2}}{2x^{2} + xy - y^{2}} = \frac{(x + y)(x - y)}{(x + y)(2x - y)}\)
= \(\frac{x - y}{2x - y}\)
