intermolecular forces - forces between molecules EX: HCl-HCl intramolecular forces - hold atoms together in a molecule Ex: H-Cl Types of intramolecular forces - 1. Ionic 2. Covalent - Polar covalent - nonpolar covalent nonpolar covalent bond - bond between atoms with same electronegativity polar covalent bond - bond with unequal sharing of electrons the lower the pka the - stronger the acid Buffers are ___ - solutions that resist changes in pH when strong acids or bases ...

List the 3 different fluid compartments of the body. - ANSWER Intracellular Fluid, Interstitial Fluid, Plasma What is the definition of homeostasis? - ANSWER The regulation of the body's internal environment in a narrow range Describe the difference between intrinsic and extrinsic regulation - ANSWER Intrinsic is local to the regulated area. Extrinsic is regulating an area from somewhere else usually the nervous or endocrine system. Describe the difference between a feedback and feed-...

The central dogma of molecular biology refers to transcription and translation. Transcription completes the process using DNA's to make_____whereas translation is using_____to make proteins. - RNA's, RNA's Cell membrane is formed by two layers of phospholipids. Therefore, the thickness of cell membrane is within the size range of - Macromolecules most elements are neutral because they have equal number of electrons and protons. Normal carbon 12C, has 6 electrons, 6 proton, and 6 neutron...

Bio 115 Final Exam (Dr. Barry WVU) Questions and Answers 100% Pass Adjacent water molecules are connected by the ______ electrical attraction between the hydrogen of one water molecule and the oxygen of another water molecule Hydrogen bonds play a role in the _____ structure of proteins. Tertiary and Secondary Which of the following types of molecules are the major structural components of the cell membrane? Phospholipids and Proteins A hydrolysis reaction REQUIRES ... Select all ...

What are sphingomyelins? - Sphingolipids where the head group is phosphocholine or phosphoethanolamine. What prevents cells from actually swelling? - It is effectively impossible for sodium to enter the cell (due to pump and lack of sodium channels). There is a high sodium ion concentration outside the cell which prevents water from entering in the cell Why would cells have a tendency to swell? - Because cytoplasm contains negatively charged proteins that cannot exit, so cells naturally ga...

Dehydration Small molecules combine to form larger ones. For example: sugar monomers combine to form starch polymers Hydrolysis One larger molecule is split by the addition of H+ and OH- (from water) to the components Polymers large chains of identical molecular units strung together Monomers the units that serve as the building blocks of polymers Another name for a dehydration reaction is... condensation reaction Cells contain ___ major families of sma...

Anatomy - studies the form and structure of the body Physiology - examines how the body func ons cytology - study of body cells and their internal structure Pathophysiology - relationship between the func on of an organ system and disease or injury to the system Characteristics That Describe Living Things - organization, metabolism, growth and development, responsiveness, regulation, reproduction Muscular System - -Locomotion -Heat production (Muscles,Tendons) endocrine sys...
