Genetics + DNA
DNA is comprised of these building blocks that attach, joining both sides of the double helix.
What are nucleotides?
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?
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, also know as nucleic acids, 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 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?
These traits are also known as genetic and epigenetic traits.
What are heritable and non-heritable traits?
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?
