Q

What was the critical value used in the anthropod experiment, and why was it significant?

A
  • 3.84
  • If the chi-square value was less than 3.84, I failed to reject the null hypothesis
  • If the chi-square value was greater than 3.84, the null hypothesis was rejected and the alternate hypothesis was accepted

A

Monocot: Corn/grass
Eudicot: Carrot/ African Violet

22
Q

A

light, large-celled wood

24
Q

What is summer wood?

A

Denser, darker, small celled sectios

25
Q

Where is the heartwood?

A

At the center of the cross section

26
Q

What is the bark made of?

A

Cork and phloem

27
Q

From the outer to inner sections, what is the order of the phloem, xylem, and cork?

A

Cork, phloem, xylem

28
Q

What is the outermost layer of a flower that serves to protect the developing bud?

A

-Sepals

29
Q

What is the layer of a flower just inside the sepals that serve to attract pollinators?

A

-petals

30
Q

What are the sterile parts of the flower?

A

Sepals and petals

31
Q

What are the reproductive parts of the flower?

A

Pistil and stamens

32
Q

What is the male part of the angiosperm and what is it composed of?

A
  • stamens

- composed of a filament and an anther

33
Q

What does the anther do?

A

produces pollen wihich carries the male haploid cells

34
Q

What is the female part of the plant?

A

Pistil

35
Q

What is the pistil composed of?

A

The over, style, and stigma

36
Q

Which part of the pistil is receptive to pollen?

A

Stigma

37
Q

How does pollination occur?

A

When pollen is transferred from the anther to the surface of the stigma

38
Q

What is the fruit composed of?

A

the ripened ovary plus the enclosed seeds

39
Q

True or false: The sepals, petals, stamens, and pistil compromising a flower are modified leaves.

A

True

40
Q

What part of the plant are the buckeyes that are worn on necklaces?

A

seeds

41
Q

According to Robert MacArthur and E.O. Wilson and their theory of island biography, what were the two biggest contributors to the diversity found on islands?

A
  1. Size of the Island

2. Distance of the island from the mainland

42
Q

McArthur and Wilson viewed the flora and fauna of islands as an equilibrium between what two forces?

A

immigration of new species to the island from some source area and extinction of those that have already arrived

43
Q

What is the area effect?

A

A larger island should have more species at equilibrium between immigration and extinction than a smaller island the same distance from the source area

44
Q

What two things dealing with island theory did the Island Biography and Conservation experiment look at?

A

Lake Eerie and Forest Frogs

45
Q

What did the Biological Dynamics of Forest Fragments Project do?

A

investigated questions associated with the destruction of tropical rain forests by setting up a series of islands of rain forest habitats amongst cleared land. The forest habitats ranged in size and the forest dynamics were monitored.

46
Q

What is autecology?

A

The branch of ecology that concerns itself with the individual organism or the individual species.
