_________ structures served a purpose in ancestral forms, but no longer are of use in modern species. For example, a pelvis in whales:
Vestigial
What is taxonomy?
the branch of science concerned with classification, especially of organisms
If a cell has a nucleus, can it be part of a bacteria kingdom?
no, archaebacteria and eubacteria are prokaryotes
The producers have 4000 kcal (energy units), how many kcal would the snake receive in this chain?
double points: label the kcal every organism would inherit in the chain
producer - 4000
rabbit - 400
snake - 40
eagle - 4
Correctly order the levels of organization from SMALLEST to LARGEST
- community
- biome
- population
- ecosystem
- species
species, population, community, ecosystem, biome
Dad 3
What type of structures are shown?
Homologous Structures - similar structure, different functions, have a common ancestor
Which number represents the earliest ancestor?
**DOUBLE JEOPARDY: what number represents the most recent common ancestry of aves & mammalia?
1
*DOUBLE JEOPARDY: 5
Which kingdom only has multicellular heterotrophs?
animalia
__________ is the term for the recovery process of an environment.
**DOUBLE JEOPARDY: what are the 2 types & what is a difference between them?
Succession
*DOUBLE JEOPARDY: primary succession (starts from bare rock & requires a pioneer species) and secondary succession (starts from soil)
All of the offspring of an organism have the same genetic material as the parent. We can conclude that this is ________ reproduction.
asexual reproduction
GMO Crops are also called t________ crops.
Transgenic
What type of structures are shown?
Analogous Structures: different structures, same function, no common ancestor
Which 2 options show a clade?
B & D
What kingdom is only autotrophs?
plantae
What trophic level is the algae?
Double points: correctly label every item in the food chain
algae - producer
zooplankton - primary consumer
small fishes - secondary consumer
squid - tertiary consumer
shark - apex predator
Correctly label each organism with the type of producer/consumer they are.
sun is only an energy source, not a producer/consumer
plant - producer
grasshopper - primary consumer
mouse - secondary consumer
snake - tertiary consumer
List 2 advantages and 2 disadvantages of GMO crops.
Advantage Examples:
- more crops per plant
- better quality crops
- frost/weather resistant crops
Disadvantage Examples:
- possible resistance
- financially unfair access to GMO technology
Correctly place the following traits in the venn diagram:
- creates genetic diversity
- occurs in somatic cells
- requires a mate
- occurs quickly
asexual: occurs in somatic cells, occurs quickly
sexual: requires a mate, creates genetic diversity
Which classification tool is shown below?
**DOUBLE JEOPARDY: Using this tool, which teacher: has hair, no doctorate degree, & no cat
1. a - has hair............................................go to 2
b - doesn't have hair........................Coach Cook
2. a - has a doctorate degree....................Dr. Lewis
b - does not have a doctorate..................go to 3
3. a - has a cat..................................Ms. Jacobson
b - does not have a cat............................Mr. Liu
Dichotomous Key
Double Jeopardy: Mr. Liu
Which kingdom prefers harsh conditions?
archaebacteria
What type of population growth is shown?
For double points: why doesn't this type of growth happen in the natural world?
Exponential
Double jeopardy: because exponential growth requires unlimited resources which does not happen in the natural world
Define natural selection.
Answers vary.
The organisms that are best adapted to their environment will survive over organisms that are not as well adapted.
Cystic fibrosis is treated using ____ _______. This process replaces defective genes with healthy genes and inserts them into a person using a virus or other vector. The virus cannot be a harmful virus.
Gene therapy
Penguins in region CHAMPA originally had short beaks. Their primary food, clams, evolved to have thicker shells. The penguins with the shortest beaks could not reach their food in the clams. Over time, the penguins evolved to have longer beaks as that allow them to reach food. What is this process called?
coevolution

Family
Genus
Species
What are the names of the 6 kingdoms?
Eubacteria, archaebacteria, protists, fungi, plantae, animalia
What type of population growth is shown?
For double points: what is the term for the dotted red line where the graph's curve levels off?
Logistical growth
Double jeopardy: Carrying capacity, this is the maximum number of organism an ecosystem can stably support
Explain endosymbiotic theory.
Answers vary.
Prokaryotic cells engulfed one another, mitochondria & chloroplast are important examples, leading to eukaryotic cells.
