3 10 Characteristics of Life When it’s hot outside, you sweat.

4 10 Living things need to maintain homeostasis. Characteristics of Life

5 20 Characteristics of Life If you cut yourself, a scab will form.

6 20 Characteristics of Life Living things must grow and develop.

7 30 Characteristics of Life Change that occurs in a species overtime in response to the continuously changing environment

8 30 Characteristics of Life Living things evolve.

9 30 Characteristics of Life

10 40 Characteristics of Life A plant moves towards the sun.

11 40 Characteristics of Life Living things must be able to respond to stimuli

12 50 Characteristics of Life All living organisms share similar instructions to run cell processes and pass on hereditary information.

13 50 Living things must have Deoxyribose Nucleic Acid (DNA) Characteristics of Life

14 10 What is an independent variable? Lab Skills

15 What the experimenter is testing, should only be 1! 10 Lab Skills

16 20 What is a dependent variable? Lab Skills

17 The biological response or what the experimenter measures 20 Lab Skills

18 30 Why do we need controlled variables? Lab Skills

19 To ensure we are testing only one independent variable 30 Lab Skills

20 40 What should you do with your hypothesis after your experiment? Lab Skills

21 *Accept- data collected in the experiment supports it. *Reject- data collected does not support it. 40 Lab Skills

22 50 What do we call the “placebo” group in an experiment, and why is it essential? Lab Skills

23 50 The Control Group- to use as a standard for comparison. Lab Skills

24 10 Ecology Overview List the ecological levels of organization from least inclusive (specific) to most inclusive (broadest)

25 Organism, Popululation, Community, Ecosystem, Biosphere 10 Ecology Overview

26 20 Define Ecology. Ecology Overview

27 The study of how organisms interact with their environment and each other. 20 Ecology Overview

28 30 A group of pigeons. Ecology Overview

29 30 Population

30 40 In addition to populations, ecosystems include… Ecology Overview

31 40 Abiotic Factors

32 50 The sum of all of the planet’s ecosystems… Ecology Overview

33 50 Biosphere

34 10 Population Structure Define Population Density.

35 10 Population Structure The number of individuals of a species per unit area or volume

36 20 Population Structure How do scientists determine population density and why?

37 20 Population Structure *Counting or *Sampling Techniques- it’s often impossible and impractical to count all organism in an area.

38 30 Population Structure Why would an organisms in a population take on clumped dispersion?

39 30 Population Structure *Herding patterns *social behavior *uneven distribution of resources *mating

40 40 Population Structure What are survivorship curves?

41 40 Population Structure *Graphs (curves) generated from life tables. *Looks at average life span of organisms to make determinations about population growth.

42 50 Population Structure What kind of distribution would a Cresotebush in the desert take and why?

43 50 Population Structure Uniform- competition for water

44 10 My name is Bond, Ionic Bond; Taken, not shared! Cells

45 10 Population Growth From: Mariano Cecowski Q: if both a bear in Yosemite and one in Alaska fall into the water which one disolves faster? A: The one in Alaska because it is HIJKLMNO

46 10 Population Growth Alimentary: What Sherlock Holmes said to Dr. Watson. Urinate: What a nurse would say if a patient asked her what room he's in. Urine - The opposite of "You're out!" Benign: What we want when we are eight. Intestine - Currently taking an exam CARDIOLOGY: advanced study of poker playing TERMINAL ILLNESS: getting sick at the airport

47 10 Population Growth What are the factors that limit population growth?

48 10 Population Growth Density-dependent (competition, health, predation, physiological factors) Density-independent (acidity, salinity, fires, catastrophes, weather conditions) Boom and Bust cycles (pred/prey relationships, food supply)

49 10 Population Growth

50 20 What kind of growth model is represented below, and how is it possible?

51 Exponential Growth Model- conditions are ideal, birth rates exceed death rates 20 Population Growth

52 30 What are the characteristcs of the logistic growth model?

53 30 Population Growth Idealized population growth slowed by limiting factors.

54 30 Population Growth

55 40 What is this? Analyze the data!

56 40 Population Growth Age Structure Diagram- *Decline in Population Growth *Not enough children being born to replace those who die

57 50 Population Growth What kind of growth do humans exhibit? Why is this a concern?

58 50 Population Growth Exponential Growth. *It’s ideal—and nothing’s perfect! *resources will run out *disease will spread …?
