Biology Basics

Cells = All organisms are made up of these, which process hereditary information Evolution = This explains the unity and diversity of life Energy Processing = This allows organisms to move, grow, and reproduce Regulation = All organisms are able to control their own internal environments

Molecular Biology = Study of life at the cellular level Anatomy and Physiology = Study of the structure and function of plants and animals Evolution of Populations = Study of how groups of organisms change over time

Molecular Biology = Research into the molecular mechanisms that regulate life Anatomy and Physiology = Research into the structure and function of organisms Evolutionary Biology = Research into how life forms have changed and diversified over time

<p>Observations = First step in the scientific method, involves gathering data Questions = Formulated based on observations, guides the research Experiments = Conducted to test hypotheses and answer questions</p> Signup and view all the answers

<p>-vore, -vory, or -vorous = From Latin vorare, meaning 'to devour' -phage, -phagy, or -phagous = From Greek φαγεῖν (phagein), meaning 'to eat' Carnivory = Feeding on other tetrapods Herbivory = Feeding on plants</p> Signup and view all the answers

<p>Feeding on fish and insects = Amphibians Feeding on other tetrapods = Reptiles (Carnivory) Feeding on plants = Reptiles (Herbivory) Feeding on highly fibrous plant materials = Requires complex set of adaptations</p> Signup and view all the answers

<p>Amphibians = Continued to feed on fish and later insects Reptiles = Began exploring two new food types, other tetrapods and plants Large amphibious piscivores = Earliest forms of terrestrial vertebrates 400 million years ago Medium and large tetrapods = Natural transition from insectivory to carnivory</p> Signup and view all the answers

<p>Feeding = Process by which organisms, typically animals, obtain food Evolutionary history = The evolution of feeding is varied with some feeding strategies evolving several times in independent lineages Terrestrial vertebrates = Earliest forms were large amphibious piscivores 400 million years ago Evolutionary adaptations = Specialization of organisms towards specific food sources</p> Signup and view all the answers

<p>Insectivory = Feeding strategy that led to carnivory in medium and large tetrapods Carnivory = Feeding strategy that required minimal adaptation from insectivory Herbivory = Feeding strategy that requires a complex set of adaptations for feeding on highly fibrous plant materials Piscivory = Feeding strategy of the earliest forms of terrestrial vertebrates</p> Signup and view all the answers
