Biology and Physics Quiz

Human Food Sources

• Humans obtain food from plants and animals.
• Food can be derived from both plants and animals, hence, both options a and b are correct.

Distance Traveled per Unit of Time

• The distance traveled per unit of time is called speed.

• Aluminum has 13 electrons.

Laws of Motion

• There are five laws of motion.

Pairs of Nerves in the Human Body

• There are 31 pairs of nerves in the human body.

Examples of Light Waves

• Light waves, radio waves, and X-rays are examples of transverse waves.

Body Systems (Blood Movement)

• The circulatory system moves blood throughout the body.

Cellular Respiration

• Cellular respiration needs glucose and oxygen to produce energy, releasing carbon dioxide and water as byproducts.

Light Travel in Air

• Light travels in a straight line in air.

Vascular Bundles in Plants

• Vascular bundles in plants are composed of xylem and phloem.
• Xylem and phloem are present with root hair cells.

Tube Arising from Kidneys

• The tube arising from each kidney and entering the urinary bladder is called the ureter.

Reading, Writing, etc

• Actions such as reading, writing, driving, and speaking are voluntary.

Calculating Speed

• Speed is calculated by dividing distance by time.

Gravity Discovery

• Isaac Newton discovered gravity.

Material That Traps Air

• Materials such as fur, wool, and sawdust trap air, and are good insulators.

Anemia

• Anemia is a condition where the body cells are deficient in oxygen.
• Anemia leads to tiredness and pale complexion.

Body Part Filtering Waste

• The kidneys filter nitrogenous waste from the blood.

Removal of Nitrogenous Waste

• The process of removing nitrogenous waste from the body is called excretion.

Right Atrium's Function

• The right atrium receives deoxygenated blood.

Brain Weight

• The average human brain weighs between 1500 and 1600 grams.

Oxygen Atoms

• Oxygen atoms contain 8 protons, 8 neutrons, and 8 electrons.

Toothache Cause

• A toothache is caused by a cavity in the tooth, where bacteria cause acid production that damages the enamel and nerves.

Use of Hand Sanitizer

• Hand sanitizer kills harmful germs, keeping the skin safe.

Genetic Modification Objectives

• Genetic modifications can improve plant qualities, such as making them disease-resistant, herbicide-resistant or increasing nutrient levels.

Dissolving Solids in Liquids

• When a solid dissolves in a liquid, the liquid is called a solvent.

Heat Transfer in Fluids

• Heat transfer caused by differences in density in fluids is called convection.

Atom Components

• The nucleus of an atom contains protons and neutrons.

Nephron Function

• The nephron is responsible for forming urine.

Substances Changing on Heating

• Substances that change shape or form when heated but recover their original state on cooling are undergoing physical changes.

Parts of Trachea

• The trachea consists of bronchi, bronchioles and alveoli(air sacs), where gas exchange occurs.

Best Way to Prevent Rusting

• Preventing metal rusting can be done effectively via galvanization.

Classifications of Humans

• Humans are categorized as heterotrophs.

Substance Exchange in the Body

• Exchanges of substances between blood and body cells take place in the capillaries.

Speed Calculation

• Speed is calculated by dividing the distance traveled by the time taken to travel that distance.

Direction of Motion in Forces

• Every action has an equal and opposite reaction that's acting in a parallel direction.

State Change Process

• Processes like evaporation, sublimation and condensation involve changes in the state of matter (solid, liquid, gas).

Sensory Neuron Direction

• Sensory neurons carry messages from sensory organs towards the brain.

Types of Immunity

• Innate, adaptive, and passive are three main types of immunity.

Blood Component

• Plasma is the liquid component of blood.

Cell Structure Controlling Cell Activity

• The nucleus is the part of the cell that controls the activities within the cell.

Parasite Food Source

• Parasites obtain food from a variety of sources, including plants, insects, animals, and other sources.

Important Constituent in Living Organisms

• Proteins are essential for all living organisms.

Organisms Making Their Own Food

• Organisms that can make their own food are called autotrophs.

Antibody Function

• Antibodies are proteins in blood that help fight against foreign viruses and bacteria.

Controlling Heartbeat and Blood Pressure

• The medulla oblongata controls involuntary functions such as heart rate and blood pressure.

Changes in Milk

• The transformation of milk into yogurt involves irreversible changes and is a chemical process.
