Domains and Kingdoms
All living things on Earth fall into three domains: Bacteria, Archaea, and this.
Eukarya
This is the name of the two-name system used to classify organisms based on their relation to other, closely-similar organisms.
Binomial Nomenclature
A gene is this.
A segment of DNA that codes for a specific trait or protein.
The process that results in organisms that are more fit for their environment tending to survive and produce more offspring is known as this.
natural selection
Between cells and viruses, these are the larger ones.
cells
This kingdom of organisms is defined by their ability to photosynthesize and their cellulose-built cell walls.
K. Plantae (Plants)
A diagram that represents evolutionary relationships to show how species have changed from a common ancestor is known as this. (Either name is fine.)
Phylogenic Tree (Cladogram)
The ratio (or percentage) of an allele to the total of all other alleles of the same gene within the population is...
Traits that allow individuals within a population a better chance at survival are known as these.
adaptations
Unlike cells, which are naturally coved in a membrane of lipids, viruses are encased in a shell made of this macromolecule.
protein
prokaryotic
The two-name system used for creating the scientific names for organisms utilizes these two taxons. (Make sure they are in the correct order.)
Genus and Species
The various genes present within an interbreeding population is considered their this.
competition
This Hungarian scientist became a staunch advocate for hand washing in the medical field after seeing how it greatly reduced the mortality rate amongst his patients.
Ignaz Semmelweis
Although they are mostly unicellular, this kingdom, including amoebas and paramecia also contain nuclei.
This is the taxon after Class when going from largest to smallest.
Order
In meiosis, genetic variation is increased by these two events. We spoke about them in detail in Unit 5. (Name both of them and the phases in which they occur.)
Crossing Over (Prophase I)
Independent Assortment (Metaphase I)
When new species emerge from a singular, common ancestor and reach the point to where they no longer interbreed, it is called this.
speciation
Viruses are considered nonliving due to their non-cellular structure and inability to reproduce. This is also why we can't use these against them.
antibiotics
chitin
The organisms of the kingdom Animalia are known for their mobility, lack of cell walls, and being this, which refers to their need to consume other organisms for food.
heterotrophic
Genetic variation can be the result of mutations, sexual reproduction, and this, which involves an organism from one population moving to another and adding their own, unique traits. Immigration to the United States from other countries is an example of this.
gene flow
Francesco Redi and Louis Pasteur both did experiments to disprove this incorrect theory that claimed living organisms came from nonliving materials.
Theory of Spontaneous Generation
