Biology

1. 1The largest group of marine anthropods is the class [blank_start]crustacean[blank_end].

   1. Acrustacean
2. 2Crustaceans are the most numerous animals in the [blank_start]oceans[blank_end] but some crustaceans live in [blank_start]fresh water.[blank_end]

   1. Aoceans
   2. Bfresh water.
3. 3Most crustaceans are free-living, but some are [blank_start]sessile[blank_end] and a few are even [blank_start]parasitic[blank_end].

   1. Asessile
   2. Bparasitic
4. 4Like other Anthropods, Crustaceans have an [blank_start]exoskeleton[blank_end] which is made of [blank_start]chitin[blank_end] and [blank_start]calcium[blank_end].

   1. Aexoskeleton
   2. Bchitin
   3. Ccalcium
5. 5The exoskeleton provides protect and gives [blank_start]support[blank_end].

   1. Asupport
6. 6This segmented exoskeleton creates [blank_start]joints[blank_end], allowing the crustacean to move its body and appendages.

   1. Ajoints
7. 7The body is divided into three parts, a [blank_start]head[blank_end], [blank_start]thorax[blank_end], and [blank_start]abdomen[blank_end]. Usually the head and thorax are fused to become the [blank_start]cephalothorax[blank_end].

   1. Ahead
   2. Bthorax
   3. Cabdomen
   4. Dcephalothorax
8. 8The head carries two pairs of [blank_start]appendages[blank_end] which are used for sensing and [blank_start]feeding[blank_end].

   1. Aappendages
   2. Bfeeding
9. 9The eyes and three pairs of [blank_start]appendages[blank_end] complete the head.

   1. Aappendages
10. 10Most crustaceans have a [blank_start]carapace[blank_end], or shell that covers the thorax area.

    1. Acarapace

11. 11Located on the cephalothorax are a pair of legs that end in claws. These appendages are known as [blank_start]chelipeds[blank_end]. They are used for grabbing and holding food.

    1. Achelipeds
12. 12The [blank_start]four[blank_end] pair of walking legs are connected to the cephalothorax.

    1. Afour
13. 13The abdomen contains swimming legs called [blank_start]swimmerets[blank_end] and a fan shaped tail containing the [blank_start]uropod[blank_end] and [blank_start]telson[blank_end].

    1. Aswimmerets
    2. Buropod
    3. Ctelson
14. 14The crustaceans have an [blank_start]open[blank_end] circulatory system and no [blank_start]heart[blank_end].

    1. Aopen
    2. Bheart
15. 15The nervous system is very simple. There is a [blank_start]ventral[blank_end] nerve cord that ends in a ganglion at the [blank_start]anterior[blank_end] end.

    1. Aventral
    2. Banterior
16. 16The animal kingdom is divided into two groups. The [blank_start]vertebrates[blank_end] and the [blank_start]invertebrates[blank_end].

    1. Avertebrates
    2. Binvertebrates
17. 17The [blank_start]vertebrates[blank_end] are animals with [blank_start]backbones[blank_end].

    1. Avertebrates
    2. Bbackbones
18. 18The [blank_start]invertebrates[blank_end] are animals without [blank_start]backbones[blank_end].

    1. Ainvertebrates
    2. Bbackbones
19. 19The Phylum [blank_start]Porifera[blank_end] contains members who have the simplest body structure of any animal.

    1. APorifera
20. 20The [blank_start]sponge[blank_end] belongs to the Phylum Porifera.

    1. Asponge
21. 21The word Porifera means [blank_start]pore bearing[blank_end].

    1. Apore bearing
22. 22Sponges have 3 body layers. The outer layer in the [blank_start]ectoderm[blank_end], the inner layer is the [blank_start]endoderm[blank_end], and the layer in between the two layers is the [blank_start]mesophyll[blank_end].

    1. Aectoderm
    2. Bendoderm
    3. Cmesophyll
23. 23Water carrying food, nutrients, and oxygen enters the sponge through the [blank_start]incurrent pores[blank_end].

    1. Aincurrent pores
24. 24The water that enters the sponge leaves through the [blank_start]osculum[blank_end].

    1. Aosculum
25. 25In the ectoderm of the sponge are structures that aid in structure and provide defense for the sponge called [blank_start]spicules[blank_end].

    1. Aspicules
26. 26The sponge reproduces asexually by [blank_start]budding[blank_end] an [blank_start]regeneration[blank_end] and sexually by releasing an [blank_start]egg[blank_end] and [blank_start]sperm[blank_end].

    1. Abudding
    2. Bregeneration
    3. Cegg
    4. Dsperm
27. 27A [blank_start]squid[blank_end] has an internal shell.

    1. Asquid
28. 28The squid and octopus belong to the class [blank_start]cephalopoda[blank_end] which means "head-footed"

    1. Acephalopoda
29. 29All members of the Class Cephalopoda have a well defined head and foot that is divided into [blank_start]tentacles[blank_end].

    1. Atentacles
30. 30The [blank_start]octopus[blank_end] has lost its internal shell.

    1. Aoctopus
31. 31The defense mechanism of the squid is [blank_start]ink[blank_end].

    1. Aink
32. 32The Class [blank_start]Bivalvia[blank_end] makes up the second largest class of Mollusca.

    1. ABivalvia
33. 33Bivalves have [blank_start]two[blank_end] shells made of [blank_start]calcium carbonate[blank_end] which is secreted by the animal's mantle or body wall.

    1. Atwo
    2. Bcalcium carbonate
34. 34The shells are connected to the bivalves body by a [blank_start]ligament[blank_end].

    1. Aligament
35. 35The shells of the bivalves are held closed by [blank_start]adductor muscles[blank_end].

    1. Aadductor muscles
36. 36Many bivalves have a [blank_start]muscular foot[blank_end] which is used for digging in the sand and a [blank_start]sipho[blank_end]n used for breathing.

    1. Amuscular foot
    2. Bsipho
37. 37Mollusca with only one shell are known as [blank_start]univalves[blank_end]. They belong to the Class Gastropoda which is the [blank_start]largest[blank_end] class in the Phylum Mollusca.

    1. Aunivalves
    2. Blargest
38. 38All of the Gastropods have one external [blank_start]shell[blank_end], except for the [blank_start]slug[blank_end] which lives on land.

    1. Ashell
    2. Bslug
39. 39The body plan of all animals is referred to as [blank_start]symmetry[blank_end].

    1. Asymmetry
40. 40There are 3 body plans: [blank_start]bilateral[blank_end], [blank_start]radial[blank_end], and [blank_start]asymmetric[blank_end].

    1. Abilateral
    2. Bradial
    3. Casymmetric
41. 41If an animal's body can be divided down the center and form two equal images the symmetry is [blank_start]bilateral[blank_end].

    1. Abilateral
42. 42An organism with a body that does not show definite symmetry is known as [blank_start]asymmetric[blank_end].

    1. Aasymmetric
43. 43The starfish and sea anemone display [blank_start]radial[blank_end] symmetry. Therefore their body can be divided several ways and mirror images can be seen.

    1. Aradial
44. 44Radially symmetric animals do not have a dorsal and ventral they have an [blank_start]oral[blank_end] and [blank_start]aboral[blank_end] side.

    1. Aoral
    2. Baboral
45. 45The aboral side is the side of the [blank_start]anus[blank_end] and the oral side is the side of the [blank_start]mouth[blank_end].

    1. Aanus
    2. Bmouth
46. 46Directional movement is called [blank_start]tropism[blank_end].

    1. Atropism
47. 47Tropism is an orientation [blank_start]toward[blank_end] or [blank_start]away[blank_end] from a [blank_start]stimulus[blank_end].

    1. Atoward
    2. Baway
    3. Cstimulus
48. 48The orientation or response toward the stimulus is [blank_start]positive[blank_end] tropism.

    1. Apositive
49. 49The orientation or response in the opposite direction of the stimulus is [blank_start]negative[blank_end] tropism.

    1. Anegative
50. 50The process of plants bending toward the light is called [blank_start]phototropism[blank_end].

    1. Aphototropism
51. 51The [blank_start]roots[blank_end] display positive geotropism.

    1. Aroots
52. 52Light, heat, moisture, gravity, water, and electricity can all act as a [blank_start]stimulus[blank_end].

    1. Astimulus
