TEKS 7A & 7B
If a snake has vestigial bones that have similar characteristics to bones of a turtle, than that would mean that the two organisms……
have a common ancestor
What happens to an organism that inherits a camouflage trait?
they will blend in with the environment to survive and reproduce
What branch of science deals with classifying, identifying, and naming organisms?
Taxonomy
Two organisms within the same genus can be organized into several related….
Species
What is the type of rock that fossils are found in?
Sedimentary
A rabbit population exhibits variation in fur thickness in a temperate habitat. A gradual and lasting cooling in the habitat’s climate decreases the diversity of the rabbits’ fur coat thickness. What is the reason for this decrease? Will the thinner coated survive or will the thicker coated survive?
The rabbits with the thicker coat will survive.
What was the result from Redi’s experiment?
proved that spontaneous generation does not occur
Look at the diagram on question 19. All the animals to the right of the Salamander would have common characteristics of…..
claws or nails
similar in structure; common ancestor
True or false: The traits that survive and continue in the future generations are introduced by immigrating species. If true, just write true. If false, rewrite the statement to make it true.
False: The traits that survive and continue in the future generations are already present in the population.
True or false: Natural selection is a cause of a genetic change.
False: Natural selection does not cause genetic change.
What do the Kingdoms Protista, Plantae, Fungi and Animalia have in common?
They are all Eukaryotes
What is natural selection?
survival of the fittest. Best equipped for an environment will survive and reproduce.
What is mimicry in organisms?
Imitating another species in order to protect itself from predators
How is a cladogram useful to taxonomists?
It shows how groups, over time and as a result of evolution, are related.
What Kingdoms or Domains would organisms not have a cell wall?
Animalia
When looking at the position and shape of the bones of four organisms and two organisms seem more closely related to each other than the other vertebrates. This relationship is evidence by using…….
comparative anatomy
True or false: Natural selection relates to adaptations by granting a species any trait it might need for survival.
False: Natural selection does not grant a species any trait it might need for survival.
The purpose of using scientific names allows biologists to….
communicate about organisms, regardless of the language they speak.
Why do taxonomists sometimes change the system of classification?
New information regarding the structure, metabolism, and DNA of organisms are found.
