Genetics + DNA
What does the A stand for in the nucleotide bases; A, C, T, G
What is Adenine?
This term refers to an organism's ability to pass on its traits to the next generation.
What is fitness?
An example of this interaction is a tapeworm living inside an organism's intestinal tract to survive.
What is a parasitic relationship?
This level of taxonomy is the most general, where all life falls into one of three categories.
What is Domain?
This is the name of the alien species under investigation in chapter 4.
What is Astrophage?
This term is used to describe the shape of the DNA model.
What is a double helix?
Selective pressures can cause these traits, which can be either physical or behavioural.
What are adaptations?
The environmental pressure involves one organism trying to eat another organism.
What is predation?
This term refers to an organism's physical trait influenced by its genetics.
What is a phenotype?
Grace was initially chosen for the program, not as an astronaut, but as this type of professional, making him essential for communicating the crisis to the public.
What is a seventh-grade science teacher?
Nucleotide units are made up of a nucleotide base (A,C,T,G), a pentose sugar, and what other molecular group?
What is a phosphate group?
This reproduction type is what is responsible for the diversity of traits in a species
What is sexual reproduction?
This word describes an organism's specific role it fills in an ecosystem.
What is a niche?
This language is used for organism classification(Genus species).
What is Latin?
Astrophage converts stellar radiation into this type of energy, which they use for propulsion.
What is Kinetic Energy?
This term would be used to describe the following gene expression with two different alleles: Rr
What are heterozygous genes?
This biological theory describes how changes occur through mutations and/or genetic recombination over generations, developing adaptations that change a species to be better suited to their environment.
What is The Theory of Evolution?
This relationship between species has one organism benefiting while the other receives no net benefit or repercussion. E.g., mites that live at the base of your eyebrows.
What is Commensalism?
This process is when pollen from one plant comes into contact with the stigma of another plant to initiate seed production.
What is fertilization?
Ryland Grace discovers that Astrophage's reproductive cycle requires this common gas, which is abundant in Venus’s atmosphere.
What is Carbon Dioxide?
This term would refer to the following genotype: rr
What is homozygous recessive?
Charles Darwin used observational research on this group of islands to help formulate his book The Origin of Species.
What are the Galapagos Islands?
This type of interaction occurs when two different species are competing for the same ecological niche.
What is interspecies competition?
This word is used to describe changes to a species that occur from a selective pressure?
What is an adaptation?
Astrophage gets its primary energy for travel and breeding by consuming this type of energy from the Sun.
What is electromagnetic radiation/light?
