QUESTION 5 SOLUTIONS

Q5 a i ) A brooder house is a specialized enclosure for young chickens, turkeys, or other poultry, providing a warm, safe, and healthy environment during their early stages of growth (usually 0-4 weeks). It's equipped with heat sources, feeders, waterers, and ventilation systems.


Q5a ii ) _Three Causes of Cannibalism in Poultry_

1. Overcrowding: Insufficient space leads to stress, aggression, and cannibalism.
2. Nutritional deficiencies: Lack of essential nutrients, like protein or calcium, can trigger cannibalistic behavior.
3. Boredom and stress: Prolonged confinement, loud noises, or changes in environment can cause stress, leading to cannibalism.


Q5b I ) _Rainbow_
A rainbow is a colorful, arc-shaped optical phenomenon appearing in the sky when sunlight passes through water droplets in the air.


Q5b I I ) _Formation of a Rainbow_
Briefly, a rainbow forms when:
1. Sunlight enters the Earth's atmosphere.
2. Water droplets in the air refract (bend) the sunlight.
3. The refracted light is separated into its color components (dispersion).
4. The colors are reflected off the back of the water droplet and exit at a specific angle, creating the rainbow arc.

Q5 C I ) Two Types of Interactions in an Ecosystem_

1. Predation: One organism (predator) feeds on another (prey).
2. Symbiosis: Two or more organisms live in close association, often benefiting each other (mutualism) or one benefiting while the other is unaffected (commensalism).


Q5 c I I ) _Three Ways Energy is Lost in a Food Chain_

1. Heat loss: Energy is dissipated as heat during metabolic processes.
2. Waste and excretion: Undigested food and waste products remove energy from the system.
3. Death and decomposition: Energy is lost when organisms die and decompose, rather than being transferred to the next trophic level.

1. (a) i. Chromosomes are thread-like structures made of DNA and proteins found in the nucleus of most cells. They carry genetic information in the form of genes, which determine an organism’s traits and control its development and functioning



1. (a) ii 1. DNA testing helps diagnose genetic diseases and find out if someone is at risk for certain conditions.

2. It is used to match DNA from crime scenes with suspects or victims.

3.DNA testing can confirm if someone is the biological parent of a child.


1. b.i 1.Neon
2. Argon
3. Xenon


1 b11) Noble gases (He, Ne, Ar, Kr, Xe, Rn) are unreactive under normal conditions due to the fact that their atomic structure has a complete outer shell,making it difficult for other atoms to bond and also no tendency to gain or lose electrons


Ic I ) *Post-Harvest Loss*

Post-harvest loss refers to the reduction in quality or quantity of crops after harvesting, during handling, storage, and transportation.


1 c ii) Precautions to Minimize Post-Harvest Losses in Ghana*

1. Proper drying: Reducing moisture content to prevent mold growth.
2. Secure storage: Using rodent-proof stores and protecting against pests.
3. Handling care: Minimizing mechanical damage during transportation.


*Inductor (Electronics)*

1d i ) An inductor is a component that stores energy in a magnetic field when an electric current flows through it. It opposes changes in current.


1d ii ) Applications of Solar Energy*

1. Electricity generation: Photovoltaic (PV) systems convert sunlight into electricity.
2. Water heating: Solar water heaters provide hot water for domestic and industrial use.
3. Lighting: Solar-powered lighting systems illuminate homes, streets, and public spaces.
