A
Which scientist revised the taxonomic system into 5 levels of taxa?
Carl Linnaeus
Which philosopher created the first taxonomic system that was used for roughly 2000 years?
Aristotle
Describe the characteristics that algae share with plants.
They are both autotrophs that use photosynthesis to obtain energy
Why are Scientific names in latin?
Latin is a dead language so it is unchanging and it is the language of scholars.
Know the order of classification from broadest to most specific.
Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species
Describe the characteristics protozoans and animals share.
Protozoans are heterotrophs and protozoans can move place to place to obtain food
List the four important characteristics of fungi.
Eukaryotic, heterotrophs who feed in similar ways, use spores to reproduce, and need water in their environment
What changes in the environment cause saltwater blooms?
Cold, nutrient rich water at the bottom mixes with warm, nutrient poor water at the surface of the ocean. This redistributes the nutrients to the surface, allowing the algae population to rapidly increase in number
What are saltwater blooms commonly called
Red tides
What kind of organisms cause saltwater blooms?
Diatoms and dinoflagellates
What are 5 characteristics shared by all mammals?
Endothermic, vertebrates, 4-chambered hearts, skin with fur/hair, and produce milk
Describe the 3 functions of the endoskeleton.
Protects and supports the body, gives the body shape, and give muscles a place to attach
List 3 characteristics of chordates. When do most animals lose these?
Nerve cord, Notochord, and Pharyngeal arches which most lose before birth or hatching
How can birds have such a diverse range of diets among different species?
Different beak shapes allow different species to access and eat varying diets
What is the general relationship between whether an animal is an endotherm and whether it has a four chambered heart? Relate this to the animal's need for energy.
endotherms have four chambered hearts and they use energy to produce heat therefore need a lot of energy. In a four chambered heart, oxygenated blood does not mix with deoxygenated blood, which means blood reaches body tissue carries a lot of oxygen, Oxygen is needed to produce energy, enabling endothermy.
list and describe the 3 structures of a seed
embryo which the young plant develops from the zygote, cotyledon which is a seed lead that stores food, and the seed coat which acts as a plastic wrap for the seed.
Which of the following animal groups are endotherms? Which are ectotherms? Categorize amphibians, birds, fish, mammals, and reptiles.
ectotherms: fish, amphibians, and reptiles endotherms: birds, and mammals
What does amphibian mean? What is the significance of the translation?
Amphibian means "dual life". this is because amphibians begin their life as larvae in the water and as they grow and develop structures necessary for life on land, they move out of the water. They live most of their lives on land, returning to water to reproduce.
What are 2 characteristics all seed plants share?
Vascular tissue and seeds to reproduce
list and describe the 2 kinds of vascular tissue.
Xylem is where water and nutrients move through, while phloem is where food or sugar moves through
Identify and explain 2 ways mammals are adapted to live in cold climates.
endothermic so they use energy to produce heat internally, allows them to live in colder environments and a thick layer of fur or hair which prevents heat from escaping the mammal's body
How do you correctly handwrite a scientific name? How do you correctly type a scientific name?
Handwrite-underline both genus and species. Type-italicize both genus and species. For both cases the first letter of genus is capitalized while species is lowercase
How do fungi obtain their food?
Fungi grow their hyphae into the food source. Digestive enzymes ooze out from the tips of the hyphae into the food. The enzymes break the food down into nutrients they can absorb. The hyphae absorb the food.
What is the equation of photosynthesis?
6CO2 + 6H2O = C6H12O + 6O2
List and describe the ways a plant controls water loss.
Closing the stomata on hot days to avoid losing water as water vapor and producing a cuticle which is a waxy, waterproof layer to avoid evaporation of water from the leaves
