Ch.2: Chemistry
The abundance of this subatomic particle determines the elemental identity of an atom (i.e., which element it is).
What are protons?
This principle explains why two organisms occupying the same niche cannot coexist indefinitely. The superior competitor will eventually outcompete and displace the weaker species.
What is the Principle of Competitive Exclusion?
This type of symbiotic relationship is characterized by a mutual benefit to both partners participating in the relationship.
What is a mutualism (+/+)?
This is the basic unit of life.
What is a cell?
This is the type of chemical bond that results from the equal sharing of electrons between two atoms.
What is a non-polar covalent bond?
This principle explains how two organisms occupying similar niches can coexist in the same area by utilizing different parts of a resource or accessing the source at different times.
What is resource partitioning?
This type of relationship is characterized by one partner benefiting while the other is harmed.
What is a parasitism?
This refers to a collect of populations of different species that live in the same area at the same time, thus can interact with each other.
What is a biological community?
This term refers to multiple forms of the same element that differ in their number of neutrons.
What is an isotope?
This type of species is characterized by high numbers of offspring and low parental care investment.
What are r-selected species?
What is habitat loss (i.e., habitat destruction, fragmentation, and degradation)?
This refers to a collect of individuals of the same species that live in the same area at the same time, thus can mate with each other.
What is a biological population?
Besides protons, these are the other subatomic particle found in the nucleus of an atom.
What are neutrons?
This type of species is characterized by low numbers of offspring and high parental care investment.
What are K-selected species?
What is allopatric speciation?
Besides bacteria, these are the other group of Prokaryotes, which are also characterized as extremophiles.
What are Archaea?
This refers to the outermost electron shell that holds the electrons that participate in chemical bonding.
What is the valence electron shell?
What combination of size (large vs small) and proximity to mainland (far from or close to) is expected to foster the greatest degree of biodiversity?
What are large islands near mainland?
Daily Double: Explain how habitat fragmentation negatively impacts biodiversity.
Any acceptable answer.
This Domain of organisms is characterized by the presence of a nucleus that contains the DNA and contains the following groups of organisms:
-Plants
-Animals
-Fungi
What are Eukaryotes?
