DNA (LS1-1)
The name of each letter of DNA in a gene/genome
What is a nucleotide?
What the earliest cells without a membrane-bound nucleus were called.
What are prokaryotes?
The age of the Earth.
~4.5 Billion Years
The benefit of having eyes on the top of your head (example: beavers, alligators, etc)
To see prey/predators above the water.
A segment of DNA which usually codes for some specific feature in an organism.
What is a gene?
These are the command centers of the cell which direct cellular activity.
What is the nucleus?
Unicellular eukaryotes which gave rise to fungi, plants, and animal kingdoms.
What are protists?
The two things required for evolution
Reproduction and Mutation/Diversity
The type of fossil that occurs when an organism dies, water moves in causing the organism to decay, leaving behind an impression.
What is a mold fossil?
Long strands of DNA containing genes that are wrapped up into compact structures that look like X's.
What are chromosomes?
If a cell is lacking in ATP (cellular energy), which organelle could be faulty in a eukaryotic cell?
What is the mitochondria?
The 8 levels of Taxonomy from most general to most specific.
What are Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species.
The term for an organisms that survives long enough to reproduce the most.
What is fitness/the most "fit" individual?
The type of fossil that occurs when the impression of an animal is filled with another material, hardens and becomes a dirt copy of the original organism.
What is a cast fossil?
The name for every strand of DNA, gene, and chromosome in an organism
What is a genome?
The ways in which plant cells differ from animal cells.
What are cell walls vs cell membranes? What are chloroplasts?
The superpowers of the following plant phyla:
Bryophytes (Mosses):
Pteridophytes (Ferns):
Gymnosperms (Pines & friends):
Angiosperms (Flowering plants):
Bryophytes (Mosses): Live on land
Pteridophytes (Ferns): Develop vascular tissue
Gymnosperms (Pines & friends): Seeds!
Angiosperms (Flowering plants): Seeds + Flowers attracting pollinators
The term for two organisms that do not share a common ancestor but share similar traits/characteristics.
What is convergent evolution?
Which fossil can we extract DNA from and why can't we extract DNA from the others?
Ice preservation. DNA degrades with all other forms of fossilization.
The three different types of organelles where DNA can be found.
What are the Nucleus, Mitochondria, and Chloroplasts?
Certain types of breast cancer cells can degrade breast tissue's structural integrity (collagen, elastin, etc) by taking advantage of the each cell's garbage disposal machinery and weaponizing it. These "garbage disposal" organelles are known as...
What are lysosomes?
The name of the biological tool which can be used to use physical traits to identify species. Created like 20 questions/choose your own adventure.
What is a dichotomous key?
What is the benefit of colony behavior when talking about early multicellular organisms and how could it have led to more complex multicellularity?
Colony behavior makes you bigger (less prone to predation) AND might allow for specialized cells to evolve.
How can fossils give scientists an idea of past ecosystems?
Looking at the physical traits of organisms, scientist are able to guess the function of various anatomical features/adaptations. This could indicate what type of environment these organisms lived in.
