26
Hydrosphere

28
energy
capacity or ability to do work
29
thermal energy is heat
that flows from an object with a higher temperature (heat source) to an object with a lower temperature (heat sink)
30

is energy involved in the movement of matter
31
solar energy
the energy from the sun and includes ultraviolet radiation, visible light and infrared radiation

thermodynamics
the study of energy and its transformation
33

is self contained and it does not exchange energy and its surrounding
34
open system
exchange energy with its surroundings
35
first law of thermodynamics
energy can not be created or destroyed, although it can change from form to another
36
second law of thermodynamics
when energy is converted from one form to another, some of it is degraded into heat, a less usable form that disperses into the environment
37
organisms are divided into three categories
producers, consumers and decomposers
38
producers
(autotrophs) create organic molecules from simple inorganic substances such as CO2 and water usually use sunlight as energy
39
consumers
use bodies of other organism as their source of food energy (heterotrophs)
40
decomposers
are heterotrophs that break down organic material and use the decomposition products to supply energy

trophic level
an organisms position in a food chain, which is determined by its feeding relationships
42
a food web
a representation of the interlocking food chains that connect all organism in an ecosystem
43
Ecological pyramids
graphically represents the relative energy values of each trophic level. There are three main types of pyramids number, biomass, and energy
44
pyramids of numbers
shows the number of organisms at each trophic level in a given ecosystem, with greater numbers illustrated by a larger area for that section of the pyramid
45
pyramid of biomass
illustrates the total biomass at each successive level in an ecosystem
46
Pyramid of energy
illustrates the energy content, often expressed as kilocalories per square meter per year
47
Fields within ecology
ethology- study of animal behavior population ecology- study of populations community ecology- study of communities ecosystem ecology-study of ecosystems
48
clumped dispersal
probably means organisms is social in some way
49
uniform dispersal
probably means organism is territorial
50
random dispersal
probably means organism is not social or territorial
51
Important characteristics of ecology population
Population size: how many individuals Population density: how "packed in" indiv. are Population dispersal: how indiv. are spread out
52
population growth
how quickly is the population growing (two kinds)
53
Exponential growth
Occurs when there is no competition for resources (invasive species) (curves graph goes up)
54
Logistic growth
occurs when a population reaches a size that is too big for habitat to handle (carrying capacity) (graph curves in then out) (dotted line at top of graph)
55
Density Independence (chance)
affect all pop. in similar ways, regardless of the pop. size -unusual weather -natural disasters -certain human activities-such as damming rivers and clear cutting forests
56
Density dependent
A limiting factor that depends on pop. size -competition -predation (predator-prey relationship) -parasitism -disease
57
predator-prey relationship
prey adapt to predation --> predators adapting to get prey better --> further adaptation to predation --> repeat
58
Symbiosis
Presence of one species in an environment can impact the survival of another species (3 major types: parasitism, mutualism, commensalism)
59
Parasitism
One organisms is harmed by the presence of another. Parasites are classified by where they are found ectoparasites: outside, endoparasites: inside
60
Mutualism
When two organisms impact each other positively. Coevolution: evolution of one species impacted by another (ex. pollinators and flowers)
61
Commensalism
One species is impacted positively while another organism with no impact on the other organism
62
A correlation between structure and function
-Obtaining Nutrients -Oxygen consumption -Fight infection -Excrete waste -Reproduce -Sense/respond
63
Anatomy vs Physiology
Study of form of organism's structure vs. study of function of organism's structure
64
Cellular Level
Muscle cell
65
Tissue Level
muscle tissue
66
Organ level
heart
67
Organ system level
Circulatory system
68
Organism level
Many organ systems functioning together
69
Epithelial Tissue
Covers body surface and lines internal organs/cavities
70
Nervous tissue
Senses and transmits information received from external and internal stimuli (brain, spinal cord, nerves in body)
71
connective tissues
sparse population of cells scattered throughout a fibrous matrix they secrete (supports/binds tissues, 6 types)
72
Organ
they are higher level structure that consists of various tissues to perform a function (multiple tissues)
73
muscle tissue
long muscle fiber cells and contractile proteins (3 types, most abundant tissue in most animals)
74
Organ System
2 or more organs coordinating to accomplish a specific biological goal/function (circulatory, integumentary, urinary, digestive, and muscular system)
75
Homeostasis
Regulation of constant conditions within an animals internal environment Can relate to: pH, temperature, salinity -Internal environment can fluctuate slightly -Require to be maintained for metabolic processes
76
Analogy
The immune system works like a prison security system when a prisoner tries to escape from their cell
77
Pathogen
something that is trying to enter the body and cause an illness through the cells (are like prisoners)
78
Macrophages
are meant to locate foreign bodies and "eat them". They are like the guards
79
Inflammatory Response
it is the immune system that functions to react to pathogens. (guard beak out and try to catch prisoners)
80
1st line of defense
Skin, mucus, lysozymes
81
Skin
a waterproof barrier meant to keep pathogens from entering the body.
82
Mucous
the mucous in the nose serves as a trap for particles that enter through the nose. The nose hairs trap them in a thick layer of mucous
83
Lysozymes
can be in the form of tears and saliva. when pathogens enter the mouth, saliva washes the pathogens off the teeth. Tears are able to wash away pathogens.
84
Histamine Response
when blood flow (blood pressure) is increases and phagocytes are attracted.
85
Humoral Response
response in the immune system denotes immunologic responses that are mediated by antibodies
86
Cell- Mediated Response
the cell mediated response in the immune system is when killer T-cells attack any cell that contains a pathogen.
87
Helper T and B cells
the helper T-cells activate both B-cells and killer T-cells
88
Memory B cells
function is to remember any previous infection so that when the infection comes back the immune system is able to stop it easier
89
Killer T cells
function to attack and destroy the infected cells
90
Evolution
change in gene frequency in a population over time
91
