Comparative Anatomy (Chapter 7&8)

3. Exerts an important force on a large mass
5. An extinct group of mammals that comprise 18 known genera from the early Cenozoic
7. largest placoderm (extinct)
8. Cell division and proliferation under stress
11. A condition if it experiences increased stress, tissue tends to increase in prominence
14. The study of how physical forces affect and are incorporated into animal designs
15. Describe measurements of variables with a magnitude and a direction
17. A deep-water squid, largest living mollusk
20. common water flea
21. Nearsightedness, image focused in front of the retina
22. Largest extinct land mammal
24. Study of size and its consequences.
26. The resisting force, may arise from various physical phenomena; resisting force exerted by fluid in the opposite direction to the animal’s body motion.
29. Unit of work
31. Devices that transfer forces
32. The difference in the appearance of an object when it is viewed from two different points
33. A network of intertwining vessels
35. Standards of measurement that, when attached to length, time, and mass, give them concrete values
36. The force applied to an object times the distance the object moves in the direction of the force with a:
37. A condition if living tissue is unstressed, it tends to decrease in prominence
38. Unit of pressure
40. Farsightedness, if the image falls behind the retina
42. Amount of space ( L x W x H).
43. A concept of the flow of events

1. Mass divided by volume
2. A measure of force(a result of gravity)
4. The rate of change in its velocity
6. The tendency of a submerged object in a fluid to sink or to rise
9. The rate of change in an object’s position
10. The tendency of a body to resist a change in its state of motion
12. The oldest of the physical sciences
13. Force divided by the area over which it acts—pounds ft-2 or N m-2 for instance
16. Where the flow is nonchaotic
18. The unit of power
19. Tallest living land animal
23. A transformation where tissues can, under some circumstances, change from one type to another
25. The rate at which work gets done, therefore power equals work divided by the time it takes
27. Today the largest flying bird; a fossil bird from South America had an estimated wing span of 20 feet
28. At 43 feet is the longest extinct snake
30. Linear measurement (point A to point B) .
34. Natural instabilities in the boundary layer may cause the fluid to become chaotic
37. The change in shape in correlation with a change in size
39. Describes the effects of one body acting on another through their respective mass and acceleration
41. Largest extinct bird
44. A concept of inertia
