These two organisms are the most recently evolved organisms on this cladogram.
What are the lion and the squirrel?
100
This body system includes the lungs.
What is the respiratory system?
100
This is a group of similar cells that all perform the same function.
What is a tissue?
100
This plant organ is for reproduction.
What is the flower?
100
This is the smallest level of organization. It is the basic unit of structure and function.
What is a cell?
200
This characteristic developed after the rattlesnake, but before the bird.
What are legs?
200
This system is like the postal service of the body, delivering items the cells needs, and picking up what they need to send away.
What is the circulatory system?
200
Several organ systems combine to form this level of organization.
What is an organism?
200
Xylem and phloem are examples of this kind of tissue that transports materials throughout a plant.
What is vascular tissue?
200
An example of homologous structures.
A homologous structure is a similar structure with a different function. A human arm and cats front leg are examples of homologous structures.
300
This is what the red circles indicate.
What is a common ancestor species?
300
This system makes sure that food is broken down small enough to enter each cell for cellular respiration.
What is the digestive system?
300
Connective, muscular, epithelial, and nervous are all examples of these.
What are tissues?
*Note: these 4 tissues are in every body system
300
An adaptation a frog has for living in the water.
What are nictitating membrane (3rd eyelid), webbed feet, eyes on top of head, camouflage for water.
300
Three requirements of a claim.
Complete sentence, present tense, answers the investigative question, can be backed up with evidence.
400
According to this cladogram, this is how many characteristics the squirrel shares with the bird.
What is three?
400
This system includes the trachea, and is responsible for bringing oxygen into the body and getting carbon dioxide out of the body.
What is the respiratory system?
400
This type of human tissue is found throughout the body, holds tissues and organs in place, and includes bones and cartilage.
What is connective tissue?
400
Flowers, stems, and leaves make up this organ system of a plant.
What is the Shoot system?
400
Even though a species is extinct, a scientist can study its evolution using these, if they are available.
What are fossils?
500
These are the most closely related organisms on this cladogram, and this is how you can tell.
What is the squirrel and the lion because they have the most recent common ancestor on the cladogram, AND because they have the most (four) common characteristics of any two organisms.
500
These are the tiniest type of blood vessel, where gases exchange with a cell.
What is a capillary?
500
This type of tissue lines organs for protection.
What is epithelial?
500
An adaptation a frog has for living on the land.
What are lungs, a tongue for eating flying insects, legs for jumping.
500
This can be inferred if two organisms have homologous structures.
The organisms share a common ancestor.
