Bonds
This type of interaction is a non-covalent bond that forms between a hydrogen atom and a fluorine, oxygen, or nitrogen atom in different molecules.
What is a hydrogen bond?
This is the process by which organisms better adapted to their environment tend to survive and produce more offspring.
What is Natural Selection?
This buffer contributes to pH stability in human blood.
What is carbonic acid?
This type of solution has a pH value greater than 7.
What is a basic solution?
his is a property that arises from the arrangement and interaction of parts within a system, which cannot be observed in the individual components.
What is an emergent property?
This type of bond is formed when two atoms share a pair of electrons.
What is a covalent bond?
This condition of natural selection occurs when there is genetic variability among organisms in a population.
What is variation?
This is the pH value of a neutral solution
What is 7?
This ion is formed when a hydrogen ion binds to a water molecule.
What is a hydronium ion (H₃O⁺)
This type of bond is typically found in salts and is formed between metal and non-metal elements.
What is an ionic bond?
The ability of an atom to attract electrons in a bond is described by this property.
What is electronegativity?
This genetic disorder, caused by a mutation in the hemoglobin gene, provides a survival advantage against malaria in certain populations.
What is sickle cell anemia?
Solutions with a pH less than 7 are classified as this.
What are acidic solutions?
This term describes a substance that donates a proton (H⁺) in a chemical reaction.
What is an acid?
The concentration of hydrogen ions (H⁺) in a solution with a pH of 4 is this many times greater than in a solution with a pH of 7.
What is 1,000 times?
When a bond is described as "partially ionic," it indicates that the bond has characteristics of both ionic and covalent bonds. This term is used to describe bonds with this level of electron sharing.
What is polar covalent?
The three conditions required for natural selection to occur
Buffers help maintain pH by neutralizing added acids or bases. They do this by combining with these ions to form stable compounds.
What are hydrogen ions (H⁺) and hydroxide ions (OH⁻)?
Weak acids are reversibly and accept back what ions?
What are hydrogen ions.
Name the five unifying themes that help to organize biological information.
What are Organization, Information, Energy and Matter, Interactions, and Evolution?
