Diversity of Living Things
The system used to name organisms using two names (genus and species)
What is binomial nomenclature?
What is DNA?
He is known as the "father" of evolution
Who is Charles Darwin?
The main function of the digestive system is..
What is breaking down nutrients?
What is photosynthesis?
The three domains used to classify all living things are
What are Bacteria, Archaea, and Eukarya?
The process where individuals with advantageous traits survive and reproduce more successfully
What is natural selection?
This organ is responsible for pumping blood throughout the body
What is the heart?
This plant tissue is responsible for transporting water and minerals from the roots to the leaves
This kingdom contains multicellular, autotrophic organisms with cell walls made of cellulose
What is Plantae?
During meiosis, this process increases genetic diversity by exchanging DNA between homologous chromosomes
What is crossing over?
Name one piece of evidence that supports the theory of evolution
What are fossils, homologous structures, or DNA similarities?
What is homeostasis?
The function of the stomata on leaves is..
What is gas exchange?
or
What is controlling water loss?
A tool scientists use to determine the classification of an unknown organism based on its traits
What is a dichotomous key?
The different versions of a gene that determine traits are..
What are alleles?
This type of evolution occurs when two unrelated species develop similar traits because they live in similar environments
These structures in the lungs allow for gas exchange
What are alveoli?
This hormone controls plant growth in response to light direction
What is auxin?
Why do scientists prefer using scientific names rather than common names?
Because scientific names are universal and avoid confusion across languages and regions.
In a monohybrid cross between two heterozygous parents (Tt X Tt) , the expected genotype ratio is..
What is 1:2:1 ?(1 TT 2 Tt 1 tt)
The difference between microevolution and macroevolution
Micro = small genetic changes
Macro = new species over long periods
