Multicellularity - Study guides, Class notes & Summaries

what did multicellularity lead to? - need for a highly coordinated system to regulate and integrate the physiological functioning of different cells within one organism mode of hormonal communication? - chemical signalling examples of types on triggers? - location, visual, language, sound, gesture visual trigger - circadian rhythms location trigger - sender to receiver language trigger - chemical signalling gesture trigger - social, stress, sex sound trigger - lactation what is the unit...

the purpose of the development of a vacuole is correct answers digest food, regulate excess water and regulate internal environment if a virus that normally infects cells in the lining of an elephant's lungs enters a rhinoceros correct answers it cannot infect the rhinoceros because a virus is specific to a cell type and a species photoheterotrophs get their energy from blank and their carbon source is correct answers light carbon source chloroplast arose twice on a phylogentic tree ma...

Multicellularity might have evolved from coloniality. correct answers true Some of Pasteur's sterile water flasks are still on display today. correct answers True Both mitochondria and chloroplasts have two membranes. correct answers true Protenoid spheres could have evolved via correct answers self assembly Conifers evolved in the correct answers Permian The ___ is the period of the first vascular plants. correct answers silurian Most scientists think the earth is ___ years o...

Endosymbiosis a mutually beneficial relationship in which one organism lives within another advantages of multicellularity 1. Organization of many cells into a single mass reduces SA to V ratio 2. Permits subdivision of labor amongst different tissues (specialization) origins of multicellularity 1. Intercellular connections (loss of cell wall in animal cells creates vulnerability) 2. cellular specialization 3. Communication (division of labor of cells means they must work together) 4. Evolutio...

what animals must do? - - Mechanism for excreting waste - Mechanism for development and growth - Energy input Disadvantage of multicellularity - Need special cell/cell connections Need for cell/cell communication Need system for distribution of nutrients What traits to animals share? - Eukaryotic, heterotrophic, able to move Why is the fossil record incomplete? - Needs to die near water, fossilization process needs to be in a situation where there's no oxygen present, rapidly covered in...

WIS2552 Exam 1 (Topics 1-8, Global Patterns in Biodiversity) Questions With Verified Answers The endosymbiosis theory argues that a ____ relationship was established between two cells. - answermutualistic The endosymbiosis theory argues that small prokaryotic cells were engulfed by ____. - answerlarger prokaryotic cells The first hominids appeared at the end of the ____. - answerTertiary The first fungi evolved in the ____. - answerOrdovician Francisco Redi did an experiment to show tha...

What is the goal of bioremediation? - To clean up areas polluted with toxic compounds using bacteria Broad-spectrum antibiotics inhibit the growth of most intestinal bacteria. Consequently, assuming that nothing is done to counter the reduction of intestinal bacteria, a hospital patient who is receiving broadspectrum antibiotics is most likely to become - deficient in certain vitamins and nutrients If prokaryotes did not exist, what would change in the nitrogen cycle? - The rate of movement ...
