Chap 1: The Study of Life pt1 What is Biology? The · Life is organized study scientific life of Atoms make up Molecules & mareomelules · Bio-life ology Study of - make = - Cells · Living things acquire materials · and energy Tissues make up Organs - We eat and drink to get energy· Energy Energy All in is the free our of the our cells . capacity make up Issues · - . up cells to work. embolism biochemical reactions Living things reproduce, develop & grow : Reproduction: Living things make more of themselves Sexual and asexual reproduction Have genetic material (DNA) and genes (DNA sequence that produces a protein) Development: Growth and changes in an organism over time Living things respond to stimuli Sense and interact with the environment A behavior is a response to a stimuli Plants grow towards a light source A bacteria swims towards a higher concentration of food A mouse runs away from a cat Behavior is directed towards 3 things: Avoiding injury/predation Acquiring food Reproduction Living things have a constant internal environment # Each cell maintains internal environment. Organ systems work These constant conditions are together to maintain a constant homeostasis environment in the organism. / & Literally translates to “staying the same” Deviating from homeostasis results in L illness and death Cellular & organismal homeostasis Constant supply of nutrients & energy, - removal of wastes Ex. Of homeostasis - ↑ ~ Living things are adapted to their way of Body temp = 37 degrees cel life Salt contraction of blood = 0.9% pH of bodily tissues = 7.4 Have adaptations that allow them to survive better in their environment and have more Adaptations and evolution offspring.
