Natural Selection
This person is the founder of modern evolution theory
Who is Charles Darwin?
The interior of the phospholipid bilayer has this relationship with water.
What is nonpolar (or hydrophilic)?
A process of cell division that produces two identical daughter cells.
What is mitosis?
These four nitrogenous bases make up DNA.
The four nitrogenous bases in DNA are adenine (A), guanine (G), cytosine (C), and thymine (T).
This word means factors concerning the non-living.
What is abiotic?
The random change in the frequency of alleles of a population over time.
What is genetic drift?
This is the concept where cells are separated into distinct compartments that allow simultaneous reactions to occur.
What is compartmentalization?
Four unique haploid cells is the process of this.
What are the results of meiosis?
DNA is synthesized in this direction.
What is 5' to 3'?
This type of organism captures energy from physical or chemical sources.
What is an autotroph?
Body parts with similar function but do not have similar ancestry.
What are analogous structures?
This allows for a more efficient exchange of materials with the environment.
What is a high surface to volume ratio?
Prophase, metaphase, anaphase, and telophase are the stages of this.
What are the stages of mitosis?
Adenine and guanine are this type of double ring structure.
What are purines?
A species whose absence leads to the collapse of an entire ecosystem.
What is a keystone species?
The wing of a bird and the arm of a human are examples of this.
What are homologous structures?
The model where cell membranes consist of phospholipids molecules with proteins, steroids, glycoproteins, and glycolipids that can flow around the cell.
What is the fluid mosaic model?
This is the phase of mitosis when the nuclear envelope and nucleolus disappear.
What is prophase?
This is the number of hydrogen bonds between cytosine and guanine.
What is three?
These factors are factors that intensify as population increases.
What are density dependent factors?
These membrane bound organelles indicate common ancestry of eukaryotes.
What are mitochondria (and chloroplasts)?
This structure is the site of oxidative phosphorylation and the Krebs Cycle.
What is the mitochondria?
This is the primary difference between anaphase I and anaphase II of meiosis.
What is in anaphase I, homologous chromosomes separate, while in anaphase II, sister chromatids separate?
This enzyme helps unwind the DNA strands.
This type of symbiotic relationship is one where both species benefit.
What is mutualism?
