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 measure population density and why?

37. 20 Population Structure 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
