Check answer and explanation

Answer: see the complete question and answer in detial

Explanation NOTE: The question has 4 parts each part of the question contains 5 marks Question: (a) What is the difference between fog and smog? What are the causes of smog and its effects on human health? Write a short note on one of the latest technologies to eliminate smog and avoid atmospheric pollution. (5) Difference between Fog and Smog : Fog is a natural weather phenomenon caused by condensed water vapor, while smog is a type of air pollution formed from pollutants, mainly from vehicles and industry. Causes of Smog : Smog is caused by emissions from vehicles, factories, Effects on Human Health : Smog can cause respiratory issues, eye irritation Latest Technology to Eliminate Smog : Photocatalytic materials, such as titanium dioxide coatings * (b) What is the role of oxygen-demanding wastes in water pollution? How it can be prevented? (5) Role in Water Pollution : Oxygen-demanding wastes, like organic matter from sewage, agricultural runoff, and industrial discharge, consume oxygen in water as they decompose. Prevention : Reducing pollution sources by treating wastewater, promoting sustainable agriculture * (c) What is the biosphere? Write a note on the ‘Energy Resources’ available in the biosphere. (5) The biosphere is the global ecological system that includes all living organisms and their interactions with the Earth's atmosphere, land, and water. Energy resources in the biosphere include solar energy, wind, water, and biomass, which are vital for sustaining life and ecosystems. * (d) What are the different layers of the atmosphere? On what basis these layers are classified? In which layer ‘Auroras’ are formed and where do satellites orbit? (5) The atmosphere consists of five layers : the troposphere, stratosphere, mesosphere, thermosphere, and exosphere, classified based on temperature gradients and altitude. Auroras form in the thermosphere, while satellites typically orbit in the exosphere.

2. Why Adrenaline is given to patient?

ایڈرینالین مریض کو کیوں دی جاتی ہے؟

Check answer and explanation

Answer: See the answer

Explanation Adrenaline is given in emergencies to treat severe allergic reactions (anaphylaxis), cardiac arrest, asthma attacks, and low blood pressure. Adrenaline (also known as epinephrine) increases the following effects on the heart: Heart Rate: Adrenaline increases the heart rate (positive chronotropic effect). Contractility: It increases the force of heart muscle contractions (positive inotropic effect). Conduction Velocity: It enhances the speed of electrical conduction through the heart (positive dromotropic effect). Cardiac Output: Due to the increased heart rate and contractility, adrenaline boosts the overall cardiac output.

3. Three components of the respiratory system and their primary functions?

Check answer and explanation

Answer: SHORT NOTE OF RESPIRATORY SYSTEM

Explanation Nose and Nasal Cavity: Serves as the primary entry point for air, filtering out particles, adding moisture, and warming the air to body temperature. Trachea and Bronchi: Acting as the main conducting airways (windpipe and branches), these structures carry air from the upper respiratory tract into the lungs. Lungs (specifically Alveoli): The terminal, microscopic air sacs in the lungs, where oxygen enters the bloodstream and carbon dioxide exits Last updated question01 March 2026

4. What are antioxidants and why are they used in foods? Write a short note on natural and synthetic antioxidants.

Check answer and explanation

Answer: see the complete question and answer in detial

Explanation Question: What are antioxidants and why are they used in foods? Write a short note on natural and synthetic antioxidants. (5 amrks) Antioxidants : Antioxidants are compounds that prevent oxidative damage in cells, thus extending the shelf life and quality of foods. Natural vs. Synthetic : Natural antioxidants (e.g., vitamin C, E) are derived from plants, while synthetic ones (e.g., BHA, BHT) are lab-made; both help preserve food freshness but vary in sources and stability.

5. Role of the first arriving rescuer or EMT in a mass-casualty incident?

Check answer and explanation

Answer: SHORT NOTE:Role of the first arriving rescuer or EMT in a mass-casualty incident

Explanation Role of the first arriving rescuer or EMT in a mass-casualty incident The first responder saves lives, ensures safety, and organizes care until full help arrives. They will follow these instructions: Assesses the scene for safety. Triages patients to identify who needs urgent care. Provides basic life-saving care such as CPR and stopping bleeding. Calls for backup and assists with evacuating patients. Communicates and documents patient status for the team. Last updated question01 March 2026

6. Initial steps of high-quality CPR for an unresponsive and pulseless patient?

Check answer and explanation

Answer: SHORT NOTE

Explanation Initial Steps of High-Quality CPR Ensure Scene Safety: Check the area for dangers (traffic, electricity, fire) to protect yourself and the patient. Check for Responsiveness: Tap the patient's shoulders and shout, "Are you OK?". Activate Emergency Response (Call emergency services): If the patient does not respond, immediately call emergency services (or instruct a bystander to) and get an Automated External Defibrillator (AED) if available. Assess Breathing and Pulse: Check for breathing (look for normal chest rise/fall) and a carotid pulse simultaneously for no more than 10 seconds. If there is no pulse or breathing, or only gasping (agonal breathing), start CPR. Position the Patient: Place the person on their back on a firm, flat surface. Last updated question01 March 2026
