The nature and variety of living organisms
"This characteristic of living organisms involves obtaining energy and raw materials for growth and repair through food."
Nutrition
"In these three states of matter, particles have different arrangements, movements, and energy levels. What are the three states of matter?"
Solid, Liquid, and Gas
"This formula allows you to calculate the average speed of an object based on the distance moved and the time taken."
Average speed = distance ÷ time
"What force keeps planets in orbit around the Sun?"
Gravity
"When you run, your breathing rate increases. What is the main reason for this?"
A) To cool down the body
B) To get more oxygen for energy release
C) To remove water vapor from the lungs
D) To balance your body temperature
B) To get more oxygen for energy release
"These eukaryotic organisms have a body structure made of thread-like hyphae, feed through saprotrophic nutrition, and store carbohydrates as glycogen. Examples include Mucor and yeast."
Fungus
"This separation technique is used to obtain pure water from saltwater by evaporating and then condensing the liquid."
Simple distillation
"This force opposes motion and acts between two surfaces in contact, slowing down or stopping moving objects."
Friction
"What is the most abundant gas in the Earth’s atmosphere?"
Nitrogen 78%
"Why does ice float on water?"
A) Ice is colder than water
B) Ice is less dense than water
C) Ice is heavier than water
D) Ice contains air bubbles
B) Ice is less dense than water
"These microscopic organisms have a cell wall and circular DNA but lack a nucleus. An example is Lactobacillus bulgaricus, used in yogurt production."
Bacteria
"This type of substance has a fixed melting and boiling point, unlike a mixture which melts or boils over a range of temperatures."
A pure substance
"This equation is used to calculate the weight of an object based on its mass and the strength of the gravitational field acting on it."
W=mg
"Which part of the human body is responsible for pumping blood throughout the body?"
The heart
"A farmer adds lime (calcium oxide) to soil. Why does he do this?"
A) To make the soil more acidic
B) To neutralize acidic soil
C) To improve soil color
D) To increase soil temperature
B) To neutralize acidic soil
"This type of pathogen is smaller than bacteria, lacks cellular structure, and can only reproduce inside living cells. Example includes HIV
Virus
"These three sub-atomic particles are found in an atom. They differ in charge, relative mass, and location."
Electron, Proton, Neutron
"On a speed-time graph, this part of the graph represents the distance traveled by an object over a given period of time."
The area
"If you drop a feather and a hammer on the Moon, which one will hit the ground first?"
Both at the same time because there is not atmosphere
"Which method would you use to separate sand from saltwater?"
A) Filtration
B) Evaporation
C) Distillation
D) Chromatography
A) Filtration
"These single-celled organisms can resemble either animal cells, like Amoeba, or plant cells, like Chlorella. A pathogenic example is Plasmodium, which causes malaria."
Protoctists
"This group in the Periodic Table contains elements that do not readily react because they have a full outer shell of electrons."
Noble gases / Group 0
"Which of the following factors affects thinking distance?
A) Road condition
B) Reaction time
C) Car brakes
D) Tire quality
E) Speed of the car
F) Icy road
B) Reaction time
E) Speed of the car
"What common kitchen liquid has a pH of around 2 and is acidic?"
Lemon juice (or vinegar)
"You have a cold and are sneezing. What is the most likely cause of the cold?"
A) Bacteria
B) Virus
C) Fungi
D) Protoctists
B) Virus
