A series of events that occur during the life of a cell
What is the cell cycle?
The female gamete
What is an egg?
Each contrasting form of a gene - dominant or recessive
What is an allele?
Part of Natural Selection exemplified by a sea turtle laying over 100 eggs on a beach?
What is overproduction?
The specific role played by an organism in its ecosystem
What is a Niche?
Phase when DNA will replicate itself before cell division
What is the S phase?
The number of chromosomes in a gamete
What is haploid?
The outward appearance of a trait due to the gene combination
What is phenotype?
The change in inherited characteristics in a species over the course of generations
What is evolution?
A nonliving part of an ecosystem, for example - amount of sunlight, average yearly rainfall, or pH of the soil
What is an abiotic factor?
Structure in the cell that breaks down before cell division
What is the nuclear membrane?
Phase when the chromosome number for the organism is "cut" in half
What is Anaphase ONE?
A trait with both forms of the allele - for example Aa
What is heterozygous?
Differences among individuals of the same species?
What is variation?
A constant source of energy
Organisms that will utilize energy
Recycling nutrients between organisms
What are the three factors that make an ecosystem stable?
Proteins that are responsible for moving a cell from interphase to the M (or mitosis) phase
What are cylins?
A picture of a person's chromosomes - used to diagnose gender or Trisomy-21
What is a karyotype/karyogram?
In carnations, if a red flower (RR) combines with a white (WW) flower, a pink flower(RW) results.
What is incomplete dominance?
A structure that no longer serves a purpose in an organism but is present because it once was useful in the organisms’ evolutionary past
What is a vestigial structure?
A kingdom of organisms that are heterotrophic, multicellular and digest food by secreting enzymes on to their food source
What are FUNGI?
Asexual reproduction of single celled organisms
Repair of damaged tissue
Growth
What are the reasons for Mitosis in living things?
Cell produced after two gametes combine
What is a zygote?
Traits like skin color, weight or eye color that are controlled by more than one gene.
What is polygenetic inheritance?
Evolution can not occur without this
What is sexual reproduction?
Archaea, Eukarya and Eubacteria
What are the three domains for living things?
