Question 1 of 5

What is the scientific name for the common housefly?

Correct Answer: A

Rationale: Musca domestica is the scientific name for the common housefly. This species is known for being a common pest found in and around human habitations. Drosophila melanogaster (option B) is a species of fruit fly commonly used in genetic research. Apis mellifera (option C) is the scientific name for the western honeybee. Anopheles gambiae (option D) is a species of mosquito known for being a vector of malaria.

Question 2 of 5

Which state of matter has both a definite volume and a definite shape?

Correct Answer: A

Rationale: The correct answer is 'Solid.' Solids have both a definite volume and a definite shape because the particles are closely packed together and vibrate in fixed positions. This close arrangement of particles allows solids to maintain their shape and volume, unlike liquids and gases which do not have a definite shape. Liquids take the shape of their container but have a definite volume. Gases, on the other hand, do not have a definite shape or volume as they expand to fill the space available to them. Plasma is a high-energy state of matter where atoms are stripped of their electrons and is not characterized by definite shape or volume.

Question 3 of 5

What is the unit of measurement for density?

Correct Answer: A

Rationale: Density is defined as mass per unit volume. The most commonly used unit for density in the metric system is grams per liter (g/L). Kilograms per cubic meter (kg/m³) is also a common unit for density, but grams per liter is more frequently used in everyday measurements. Pounds per square inch (psi) is a unit of pressure, not density. Newtons per meter (N/m) is a unit of force per unit length, not density.

Question 4 of 5

Which property of matter refers to the amount of space occupied by an object and is measured in cubic units?

Correct Answer: D

Rationale: Volume is the property of matter that refers to the amount of space occupied by an object. It is measured in cubic units, such as cubic meters or cubic centimeters. Mass, on the other hand, is the amount of matter in an object, weight is the force of gravity acting on an object, and density is the mass per unit volume of a substance. In this question, the key concept is the space occupied by an object, which directly relates to volume, making it the correct answer. Choices A, B, and C are incorrect as they do not specifically pertain to the amount of space occupied by an object.

Question 5 of 5

What property of a substance refers to its ability to be drawn into thin wires?

Correct Answer: B

Rationale: Ductility is the property of a substance that allows it to be drawn into thin wires without breaking. Conductivity refers to the ability of a substance to conduct electricity or heat, not to be drawn into wires. Viscosity is the measure of a fluid's resistance to flow, not related to the ability to be drawn into wires. Malleability is the property of a substance that allows it to be hammered or rolled into thin sheets, not specifically related to being drawn into wires. Therefore, the correct property for the ability to be drawn into thin wires is ductility.
