An organism whose genome has been altered by techniques of genetic engineering so that it's DNA contains one or more genes not normally found there
What is a GMO (genetically modified organism)
100
A core principal of this evolutionary mechanism is when individuals within a species having different traits that affect survival and reproduction in varying amounts.
What is Natural Selection
100
A natural or artificial reservoir that absorbs more carbon than it releases
What is a carbon sink
100
1. The main physical barrier animals use to keep out pathogens
Breeding plants and animals to produce desirable traits
What is Artificial Selection
200
This evolutionary effect is an example of genetic drift that prevents a majority of genotypes from participating in the production of the next generation tux to events such as near extinctions.
What is the Bottleneck Effect
200
This effect allows for sunlight to come through the atmosphere but is trapped as heat.
What is Greenhouse effect
200
3. These cells produce antibodies that are specific to the pathogen that has been recognized
What are B cells
300
We know for a fact that a mutation has occurred when an organism has a malfunctioning one of these, that then leads to a genetic disorder.
What is a Protein
300
This type of speciation could result within a population when individuals begin breeding at different times of the day and do not interbreed even though they are in close proximity to each other.
What is Sympatric Speciation
300
The process in which carbon moves from CO2 within the atmosphere to glucose within a plant.
What is photosynthesis
300
This is where chemical digestion of food begins
What is the mouth
400
The acquisition of DNA by genetic material from parents to offspring during reproduction
What is Vertical Gene Transfer
400
This term refers to the movement of alleles into a population from migrating individuals.
What is Gene flow
400
The process of plants absorbing water through their roots and releasing water through leaves into the atmosphere
What is transpiration
400
“Essential” ones of these must be eaten because they cannot be produced by our bodies.
What are amino acids
500
This step in gene expression leads to protein synthesis and also requires several enzymes and many types of RNA.
What is Translation
500
Genetic drift refers to changes in allele frequencies of a gene pool due to this.
What is Random Chance
500
When elk overgraze their winter food source and population growth levels, they have reached this.
