Structure & Function
This macromolecule contains the master genetic blueprints that dictate the exact sequence of amino acids in a protein.
What is DNA?
As energy moves up through an ecosystem's trophic levels, this is the average percentage of energy that is successfully transferred to the next level.
What is 10%?
In order to be moved around the body, molecules like glucose and oxygen will be transported by this body system.
What is the Circulatory System?
During sexual reproduction, this is where an offspring will inherit each half of their chromosomes from.
What is their mom and dad?
Preserved in sedimentary rock layers, this chronological chronicle of life provides direct physical evidence of past organisms and transitional forms.
What are fossils?
A segment of DNA that codes for distinct proteins that ultimately determine an organism's traits is a gene. This is the term used for different versions an individual can inherit for a specific gene.
What is an allele?
This term describes a non-native species introduced to an area that lacks natural predators, causing it to rapidly deplete local resources and harm native populations.
What is an invasive species?
This hormone is a protein that will lower blood glucose levels.
What is insulin?
All human cells contain 46 chromosomes except for these cells, which have half that amount.
What are sperm and egg cells?
Modern evolutionary biologists consider this type of molecular evidence—comparing specific nucleotide or amino acid sequences—to be the most accurate indicator of how closely related two species are.
What is DNA evidence?
The unique sequence of amino acids determines this physical property of a protein, which directly dictates its specific function in the body.
What is it's shape?
These organisms, such as bacteria and fungi, perform the critical ecosystem function of breaking down dead organic matter and returning nutrients to the soil.
What are decomposers?
These two systems work in immediate tandem to capture oxygen from the air and deliver it to working muscle cells.
What are the respiratory and circulatory systems?
This can change the order of bases in DNA, which could potentially change the amino acid sequence the DNA codes for.
What is a mutation?
This is the primary mechanism of evolution, where organisms with traits better suited to their environment are more likely to survive and reproduce.
What is natural selection?
These two processes will recycle carbon dioxide, oxygen, glucose, and water in order to use sunlight to provide energy for all of life on Earth.
What is cellular respiration and photosynthesis?
This ecological term represents the maximum population size of a species that a particular environment can sustainably support based on limiting factors.
What is carrying capacity?
When you accidentally touch a hot stove, these two systems interact to sense the danger and instantly pull your hand away.
What are the nervous system and musculoskeletal system?
During meiosis, this process occurs that increases genetic variation among individuals produced through sexual reproduction. (Hint: Think about the colored pencil meiosis diagrams we made when I used the camera!)
What is crossing over?
This evolutionary process occurs when a single ancestral species diverges into two or more distinct, non-interbreeding species.
What is speciation?
Mitosis is the cellular process allows a single fertilized egg to divide into trillions of genetically identical cells for growth and tissue repair. This is the process that will allow cells that contain the same genetic information to become specialized.
What is differentiation?
Following a severe disturbance like a forest fire or agricultural clearing, this process occurs when organisms start returning to the area in a specific order: first small producers, then large producers, then primary consumers, then tertiary consumers.
What is ecological succession?
Developing tumors will demand an increased supply of this from the circulatory system, robbing surrounding healthy tissues of oxygen and nutrients needed for growth.
What is blood or blood vessels?
This process is a type of gene regulation that can turn off genes by attaching to them and coiling the DNA so it is unreadable.
What is DNA methylation?
This type of pressure can change the circumstances a population of organisms needs to over come in order to survive, which is a driving mechanism of natural selection.
What is a selective (environmental) pressure?
