Survival & Habitat
distinctive characteristics that make an organism different from others of it's type
What are variations?
examples of this are budding, binary fission, spores, cloning, suckers, cuttings, and budding.
What is asexual reproduction?
this type of molecule carries out the functions of genetic material, and is also called deoxyribonucleic acid.
What is DNA?
This is the name for the extinction of a species, but only in a certain area.
What is extirpation?
DNA is made of coiled sugars and phosphates linked by "rungs" of pairs of these 4 types of nitrogen bases.
What are adenine, thymine, guanine, and cytosine?
one type of species evolving into a variety of similar yet separate species
What is speciation?
An adjective to describe a trait that can be inherited?
What is heritable?
This is a type of relationship between two organisms where one benefits, and the other is harmed but not killed.
What is parasitism.
This is a species that, through its ability to survive or not, shows the overall health of the ecosystem in an area.
What is a bioindicator species?
This is the process of cell division that creates two gametes (half the normal number of chromosomes each).
What is meiosis?
a type of adaptation that is related to how an organism acts and what it does
What is a behavioral adaptation?
A type of reproduction where two identical organisms are created through an equal splitting of the first organism?
What is binary fission
This is the type of biome most likely to have the highest biodiversity and the most narrow niches of specialized organisms?
What is a tropical rainforest?
This is a group of species that has the most biodiversity on earth.
What are insects (and other small insect like organisms)?
this is the process of cell division that creates somatic cells with a complete amount of chromosomes.
What is mitosis?
The type of niche associated with few species and a high number within each species, species that can withstand a wide range of different conditions
What is a broad niche?
In a flowering plant, the female sexual reproductive organ, called the pistil, includes these 3 parts.
What are an ovary, style, and stigma.
What are environmental factors. (For example, FASD & Thalidomide)
The current best guess as to the reason the dinosaurs went extinct.
What is an asteroid impact on the Yucatan peninsula?
This is the dominant allele of eye color, written in genotypic form.
What is B.
A relationship where two organisms live in direct contact and benefit each other. Starts with an s.
What is symbiosis, or a symbiotic relationship?
A single celled fertilized egg (plant or animal) is called this.
What is a zygote?
Summarize Darwin's theory of natural selection.
What are: 1. all organisms produce more offspring than can survive. 2. There's incredible variation within species. 3. some variations increase chances of survival. 4. variations get passed on and, over time, lead to genetic change.
These are three factors that contribute to the decline in biological diversity
What are extinction of species, degradation of ecosystems, and decline of populations.
This is a form of inheritance where one form of the allele is not completely shown over the other form of the allele.
What is incomplete dominance.
