What did we figure out in Africa? Flashcards
(19 cards)
Detritivore
A species that eats dead organic material.
Cecum
Between large & small intestine & helps digests plant material.
Cellulose
Complex carbs in plant wall & is what the plant cell wall is made up of.
Egest
Process of removing undigested food or waste material from and orgainsim or cell
What do organisms do w/food?
Ingest, than digest where they break things (bonds) and then release energy.
What is energy used for
perform functions & do work
biotic
living
abiotic
non-living
How does geography influence genetics?
Those who live closer together are usually more closely related because they share alleles.
What features allows herbivores & carnivores to consume their diets?
Their digestive system: cecum, stomach shape, intestine length. & dentition & skull of animal to see the tooth anatomy.
Element
simple substance that cannot be broken down by chemical reactions.
Carbohydrates
Carbon, hydrogen, & oxygen
Lipid (fat)
Carbon, hydrogen, & oxygen
Protein
Amino acids build protein. Carbon, hydrogen, & oxygen, & nitrogen.
Nucelic Acids
large molecule found in living orgainsims that store & transmits genetic info.
How can orgainsims build a new macromolecule from the foods they eat?
Orgainsims consume a macromolecule like carbs by digesting plants. Then, break down bonds & relase energy to build new macromolecule.
What are nucluic acids made up of?
carbon, hydrogen, oxygen, nitrogen; plus phosphorous (C, H, O, N, and P)
Population density
measurement of the number of orgainsims per unit of area.
Faciliation
working together & utilizing the resources orgainsims need to live in the same habitat together.
