Cellular
Carried out by autotrophs.
Creates a copy of a DNA molecule before cell division.
DNA Replication
Combining of gametes.
Fertilization
When one community gradually replaces another until a climax community is reached.
Ecological Succession
This type of mechanism helps to maintain homeostasis in the body.
Feedback mechanism.
Converts glucose into ATP.
Respiration
Chromosomes overlap and exchange segments during meiosis.
Crossing over
Type of asexual reproduction that produces a small outgrowth from the parent cell. Ex: Yeast
Budding
When a population reaches its maximum size in a particular area.
Carrying Capacity
Technique used to compare fragments of DNA.
Molecules move from high to low concentration without the need for ATP.
Diffusion/Passive Transport
A random change in a DNA sequence.
Mutation
Type of reproduction that produces offspring with more variation.
Sexual Reproduction
The specific role an organism has in its ecosystem.
The concept that species that are best adapted to the environment will survive and reproduce.
Natural Selection
Breaks down molecules into smaller subunits.
Digestion/Hydrolysis
Cell division that forms body cells.
Mitosis / Mitotic Division
When the developing embryonic cells attaches to the uterus lining.
Implantation
This occurs when organisms have the same role and require the same resources.
Competition
Technique used to cut and insert genes from one organism's DNA into another.
Genetic Engineering / Gene Splicing
Removes wastes from a cell.
Excretion
Process that creates egg cells.
Process that creates sperm cells.
Oogenesis
Spermatogenesis
Specialization of cells during embryo development.
Differentiation
Making a decision based on weighing the advantages vs. the disadvantages.
Trade-off
Technique used to compare plant pigments.
