When is nutrition important? from conception to death When considering one's health, five dimensions can be evaluated: physical health, intellectual health, emotional health, social health, and spiritual health. physical health - body's ability to perform daily functions for survival intellectual health - the cognitive ability to learn and adapt emotional health - the ability to express or s...

taxonomic diversification divergence causing a change in species name Taxonomy The scientific study of how living things are classified; like the vocabulary to the grammar of systematics Carol Linnaeus "Father of Taxonomy"; established his classification of living things; famous for animal naming system of binomial nomenclature; came BEFORE Darwin sympatric within a region Allopatric across regions taxonomic (morphological) naming of species naming based mostly on distinct measura...

when two glucose molecules combine they form a disaccharide molecule and a water molecule which of the following statements is NOT true of chemical bonds? salts are covalently bonded Which nutrient source is the easiest one for humans to break down and form ATP? glucose the water strider is an insect that skates across the water without sinking. The tips of its feet must be coated in molecules that are hydrophobic

all organisms are made of cells and come from cells Cell theory When the cell size (INCREASES or DECREASES), the membrane gets smaller compared to cell volume. increases the study of cells Cytology "how can cork float" Took sections, looked under microscope and found that they had tiny chambers (aka cells) Robert Hooke

Cytology the study of cells Robert Hooke - observed cork could float - discovered a honeycomb-like structure in a cork slice using a primitive compound microscope - only saw cell walls as this was dead tissue - coined the term "cell" for these individual compartments he saw Two types of microscopes: 1. Light Microscope 2. Electron Microscope Light Microscope - light is focused on specimen by a glass condenser lens - the image is magnified by an objective lens and an ocular lens - proj...

Which ion has greatest influence on resting membrane potential? Potassium (potassium has more leak channels on the membrane than sodium, which is why potassium has a higher permeability value and has more impact of resting membrane potential) Concerning resting membrane potential, the inside of the membrane is _______ compared to the ________ charged outside. negative, positively. T or F: The diffusion of K+ and Na+ down their chemical gradients contributes to the resting membrane potenti...
