Life-History Traits have significant features of an organism's life cycle, with particular reference to strategies influencing survival and reproduction Life History traits reflect the reality that organisms must partition limited energy and resources among activity, growth and development, and re...

Hydrophobicmolecules that do NOT interact with water Hydrophilicmolecules that can readily interact with water Semi-permeablebarrier that allows some things to enter, but not all Glycerol backboneholds fatty acid chains together Channel proteinallows movement of molecules across cell membrane, D...

Define the major motor functions of the skeletal system -skeletal system is a dynamic system of connective tissue and is a balance between production and remodeling -support, protection, movement, electrolyte and acid/base balance, blood cell differentiation Identify the major shapes of bones Flat-...

4 levels of life cell, tissue, organ, organ system 7 characteristics of life 1. organized (composed of cells) 2. acquire materials and energy (capacity to do work and metabolize) 3. homeostatic 4. reproduce 5. potential for growth 6. have evolutionary history/heredity of traits (adapt and evolve) 7...

Photosynthesis requires 2 major biochemical processes: 1. energy transduction reactions 2. carbon fixation reactions Light energy is captured and converted to chemical energy energy transduction reactions Carbohydrates are formed from carbon dioxide and water carbon fixation reactions 3 steps in ...

Haploid(genetics) an organism or cell having only one complete set of chromosomes, represented as "n" Diploid(genetics) an organism or cell having two sets of chromosomes or twice the haploid number, represented as "2n" Chromatidone of two identical "sister" parts of a duplicated chromosome,...

Function of Epithelial tissue protection, secretion, absorption, excretion and filtration Function connective tissue binding organs support and protection producing blood cells and are the most vascular What type of fibers are found in connective tissue collagen fibers reticular fibers elastic fib...

Secretion definition - the process of converting an electrical signal (presynaptic neuron) to a chemical signal (synapse) and then back to an electrical signal (post synaptic neuron) Synaptic Activity - allows neurons to communicate with one another What happens in Secretion? - the release of neur...

Energy likelihood of a reaction occurring spontaneously - depends on... 1. Pe of molecules in the reaction 2. Amount of disorder in the system Potential energy (pe) stored energy Kinetic energy (ke) energy of motion What are some types of bonds that have high pe? c-c, c-h What are som...

Predict what would happen to a plant cell if it were treated with an enzyme that digests the cellulose microfibrils Turgor pressure would cause the plant cell to swell until its plasma membrane burst, and the cell would die The ECM fibrous component consists mainly of collagen fibrils, and the grou...

Meiosis Type of cell division that reduces the chromosome number from 2n to n. Daughter cells receive the haploid number Diploid (2n) containing two complete sets of chromosomes, one from each parent. the total number of chromosomes. Haploid (n) cell condition where only one type of chromosome is ...

The potential energy that exists in the bonds of ATP or a carbohydrate is called? chemical energy Energy cycles from producers to consumers and back to producers again. false The hydrogen ions are using a membrane, channel protein to cross the membrane. Which type of movement allows the flow of th...

Why are cells the fundamental units of life? -All organisms are made up of cells. -It is the simplest collection of matter that can be alive. -So structure is correlated to cellular function. -All cells are related by their dissent from earlier cells. What are the basic features shared by all cells...

Endomembrane system components 1. Nuclear envelope 2. Endo Reticulum 3. Golgi aparatrus 4. Lysosomes 5. Plasma Membrane 6. Vesicles Endoplasmic Reticulum -extends off the nuclear envelope -a network of membrane bound compartments *rough ER and smooth ER* Exocytosis when a vesicles fuses with the p...
