Biology Class Quiz

Photosynthesis

• Plants convert sunlight into chemical energy through photosynthesis.

Cell Membrane

• The cell membrane controls what enters and leaves the cell.

Liver Functions

• The liver does not produce insulin.

Decomposers

• Organisms that break down dead organic matter are called decomposers.

Red Blood Cells

• Red blood cells are responsible for transporting oxygen throughout the body.

Cerebellum Function

• The cerebellum is the part of the brain responsible for balance and coordination.

Covalent Bonds

• When two atoms share electrons, they form a covalent bond.

Endocrine System Function

• The endocrine system primarily regulates hormone production and release.

Basic Unit of Life

• The basic unit of life is a cell.

Genotype

• The genetic makeup of an organism is called its genotype.

Kinetic Energy Formula

• The formula for calculating kinetic energy is KE = 1/2 * mv^2, where KE is kinetic energy, m is mass, and v is velocity.

Resistance Unit

• The unit used to measure electrical resistance is the ohm.

Mechanical Waves

• Mechanical waves require a medium to propagate.

Refraction

• Refraction is the bending of light when it transitions between mediums.

Plate Tectonics Theory

• The theory that explains the movement of tectonic plates is called plate tectonics.

Potential Energy

• A stretched rubber band exemplifies potential energy.

Earth's Atmosphere Composition

• Nitrogen constitutes the majority of Earth's atmosphere.

Geological Time Scale

• The geological time scale is primarily used for organizing Earth's history.

Igneous Rocks

• Igneous rocks are formed by the cooling and solidification of magma.

Evaporation

• Evaporation describes the transformation of liquid water into vapor.

Transform Fault

• A transform fault is characterized by tectonic plates sliding horizontally past each other.

Inner Core Composition

• Earth's inner core is primarily composed of iron.

Minerals

• A naturally occurring solid material made up of one or more minerals is called a mineral.

Mohorovičić Discontinuity

• The boundary or discontinuity between the mantle and the core is called the Mohorovičić Discontinuity.

Charles's Law

• Charles's Law states that the volume of a gas is directly proportional to its temperature in kelvins, given constant pressure and number of particles.

Osmosis

• Osmosis represents the natural movement of water across a semipermeable membrane.

Isomers

• Compounds that have the same molecular formulas but different structural formulas are called isomers.

Ribosomes

• Ribosomes are primarily responsible for the assembly of proteins within a cell.

Sexual Reproduction

• Sexual reproduction involves the fusion of male and female gametes to produce offspring.

Combustion Reactions

• In a combustion reaction, oxygen combines with a hydrocarbon, releasing energy and producing carbon dioxide and water.

Immune System Function

• The primary function of the immune system is to protect the organism from disease-causing agents.

Genes

• A segment of DNA or RNA that codes for a protein or RNA is called a gene.

Concave Lenses

• Concave lenses form virtual, upright, and smaller images.

Sodium Chloride Formula

• The chemical formula for sodium chloride is NaCl.

Noble Gases

• Helium is classified as a noble gas.

Hypothalamus

• The hypothalamus is a gland found in the brain that links the nervous system to the endocrine system.

Endothermic Reactions

• Endothermic reactions absorb heat from their surroundings.

Acid-Base Indicator

• A strong acid introduced to blue litmus paper will turn it red.

Supersaturated Solutions

• A supersaturated solution contains more solute than can typically be dissolved at a specified temperature.

Unit of Force

• The unit of measure for force in the International System of Units (SI) is the Newton (N).
