The Scope of Life
This branch of biology is responsible for naming and classifying organisms into groups known as taxa.
What is Taxonomy?
This is the unique number of protons in the nucleus of an atom.
What is the atomic number?
This is the strongest type of chemical bond, formed by the sharing of a pair of valence electrons.
What is a covalent bond?
This phenomenon, caused by hydrogen bonding, holds water molecules together and allows plants to transport water against gravity.
What is cohesion?
This scale is used to describe how acidic or basic a solution is.
What is the pH scale?
These are the three formal domains of life.
What are Bacteria, Archaea, and Eukarya?
These two subatomic particles are found together in the atomic nucleus.
What are protons and neutrons?
This term describes an atom's specific attraction for the electrons in a covalent bond.
What is electronegativity?
This property allows a liquid's surface to resist being stretched or broken.
What is surface tension?
These substances minimize changes in the concentrations of H+ and OH− in a solution.
What are buffers?
These new properties arise at each level of biological organization due to the specific arrangement and interaction of parts.
What are emergent properties?
These atoms of the same element differ only in their number of neutrons.
What are isotopes?
This type of weak bond forms when a slightly positive hydrogen atom is attracted to a slightly negative atom like oxygen or nitrogen.
What is a hydrogen bond?
Because it is the "dissolving agent" of a solution, water is referred to as this.
What is a solvent?
This environmental issue occurs when CO2 dissolves in seawater and reacts to form carbonic acid.
What is ocean acidification?
While plants are autotrophs, these organisms must consume others for food.
What are heterotrophs?
This is the sum of protons plus neutrons in the nucleus of an atom.
What is the mass number?
This specific type of covalent bond occurs when electrons are shared unequally due to differences in electronegativity.
What is a polar covalent bond?
This term describes a substance that is "water-fearing" and does not have an affinity for water.
What is hydrophobic?
This is the name for a negatively charged ion.
What is an anion?
These organisms are characterized as being eukaryotic, can be unicellular or multicellular, and are divided into four diverse kingdoms.
What are organisms in the Domain Eukarya?
These four specific elements make up approximately 96% of all living matter.
What are Carbon, Hydrogen, Oxygen, and Nitrogen
These weak interactions occur only when atoms and molecules are very close together and are caused by the "ever-changing" distribution of electrons.
What are Van der Waals interactions?
Water is densest at this specific temperature in Celsius, which is why ice floats.
What is 4°C?
This type of bond is formed when one atom completely transfers an electron to another, resulting in an attraction between oppositely charged ions.
What is an ionic bond?
