Entropy and disorder - Study guides, Class notes & Summaries

competitive exclusionIf there are 2 species that share the same niche in an environment then they will compete until one is eradicated Resource partitioningIf there is a tiny bit of environmental variation between the 2 species then they will share resources Fundamental nicheWhat a species could physiologically occupy Realised nichewhat the species actually occupies organisms as causal mechanismsfunctions can be understood by the applications of the laws of physics and chemistry 1st l...

BIO 100 Exam 1 Latest Version Already Graded A 1st law of thermodynamics the total amount of energy in the universe is constant and conserved 2nd law of thermodynamics all energy transfers and transformations are never competely efficient autotrophs an organism that can produce its own food binary fission asexual reproduction of bacteria bright field vs. dark field vs. phase contrast bright field shows dark specimens on a bright field, dark field shows light specimens on a dark field, a...

GCU BIO-181 Exam 2Catabolism - correct answer Metabolic pathways that break down molecules, releasing energy. Anabolism - correct answer Metabolic pathways that construct molecules, requiring energy. 1st law of thermodynamics - correct answer The principle of conservation of energy. Energy can be transferred and transformed, but it cannot be created or destroyed. 2nd law of thermodynamics - correct answer Every energy transfer or transformation increases the entropy of the universe. ...

Organisms are typically open systems. What is an example of something that is not open with regards exchanging mass? correct answers the entire earth What is the best description of the relationship between autotrophs and heterotrophs? correct answers Although an autotroph is relatively self sufficient, it does exchange matter with heterotrophs. ATP is a great source of energy that enable organisms to do work. What kind(s) of work is it used for? correct answers It phosphorylates metabolit...

What is physiology correct answers the study of how organisms work e.g. structure and function What are the three design rules for plants and animals correct answers 1. they must obey physical and chemical laws (including scaling)- diffusion, thermodynamics, pH, temp 2. they must meet demands but be economical (with appropriate safety factors) 3. they are constrained by evolutionary history What is the first law of thermodynamics correct answers Energy cannot be created or destroyed ...

prokaryote correct answers small, simple, single celled organisms adapt to change very quickly does not have a nucleus does not have membrane bound organelles have ribosomes for protein synthesis from an RNA message eukaryote correct answers true nucleus large, complex cells, make up multi-cellular organisms have organelles- specialized functions differentiation of cells to unique and specialized cell types linear DNA L amino acids correct answers the only type of amino acid used t...

energy - capacity to do work Compare potential energy and kinetic energy. Classify different energy forms into one of these two categories - potential energy is the possibility to do work: -chemical potential -concentration gradient -gravitational -stored mechanical kinetic energy -electrical -sound -radiant -thermal -motion Explain why cells need energy? Describe the types and examples of cellular work. - 1. synthetic work 2. mechanical work 3. concentration work 4. electrical ...

Metabolism correct answer: The totality of the chemical reactions that take place in living organisms. Metabolic Pathways correct answer: A sequence of steps, each controlled by an enzyme, that convert a specific molecule to a product. Catabolic Pathways correct answer: Release energy stored in complex molecules by breaking them down into simpler compounds. Anabolic Pathways correct answer: Require energy to combine simpler molecules into more complicated ones. The energy released i...
