Here are the solutions to the questions from the paper:

1. (a) Importance of materials in poultry:

(i) Perches: Provide a place for birds to roost and rest, which helps reduce stress and improve leg health.
(ii) Litter: Absorbs moisture from droppings, keeps the coop dry and clean, and provides insulation.
(iii) Hover: Provides a source of warmth for young chicks, essential for their survival and proper development.
(iv) Footbath: Used for disinfection of footwear before entering the poultry house, preventing the spread of diseases.
(v) Glowing bulb: Provides light for extended feeding periods, which can stimulate growth and egg production, and also offers warmth to chicks.

1. (b) Respiration:

(i) Differentiate between tissue respiration and gaseous respiration:
- Tissue respiration (or cellular respiration) is the biochemical process occurring within cells where organic molecules are broken down to release energy (ATP).
- Gaseous respiration (or external respiration/breathing) is the physical process of exchanging gases (oxygen and carbon dioxide) between an organism and its external environment.
(ii) Three ways in which tissue respiration is important to organisms:
- It provides energy (ATP) for all metabolic activities, such as muscle contraction, nerve impulse transmission, and active transport.
- It generates heat to maintain a constant body temperature in warm-blooded animals.
- It produces intermediate compounds that can be used as building blocks for synthesizing other essential molecules.

1. (c) Pressure:

(i) Define the term pressure: Pressure is defined as the force applied perpendicular to a surface per unit area over which that force is distributed.
(ii) Calculate the pressure exerted by the water on the diver:

State the formula for hydrostatic pressure.

$$
P = \rho gh
$$
where $P$ is pressure, $\rho$ is density, $g$ is acceleration due to gravity, and $h$ is depth.

Substitute the given values into the formula.

Given: $\rho = 1000 \text{ kg m}^{-3}$, $g = 10 \text{ m s}^{-2}$, $h = 15 \text{ m}$.
$$
P = 1000 \text{ kg m}^{-3} \times 10 \text{ m s}^{-2} \times 15 \text{ m}
$$

Calculate the pressure.
$$ P = 150000 \text{ Pa} $$ $$ P = 1.5 \times 10^5 \text{ Pa} $$ The pressure exerted by the water on the diver is $\boxed{\text{1.5 \times 10^5 Pa}}$.
1. (d) Atmospheric pollutant:
- (i) What is atmospheric pollutant? An atmospheric pollutant is any substance present in the atmosphere that has harmful or undesirable effects on human health, animal life, vegetation, or materials.
- *(ii) Three
