00:00:00,050 --> 00:00:03,350
Políferos e etnidários

2
00:00:03,350 --> 00:00:05,910
As características dos políferos

3
00:00:05,910 --> 00:00:07,710
Son os máis acuáticos

4
00:00:07,710 --> 00:00:09,830
Se deixan atascados a un substrato

5
00:00:09,830 --> 00:00:12,130
E ten unha simetría radial

6
00:00:12,130 --> 00:00:14,029
A parte dos seus corpos

7
00:00:14,029 --> 00:00:15,650
Ten pequenos buracos

8
00:00:15,650 --> 00:00:16,730
Que se chaman poros

9
00:00:16,730 --> 00:00:17,710
Que a agua flota

10
00:00:17,710 --> 00:00:20,370
Tambén ten un gran buraco

11
00:00:20,370 --> 00:00:21,989
Que se chaman osclum

12
00:00:21,989 --> 00:00:24,230
En que a agua é expelida

13
00:00:24,230 --> 00:00:25,449
A parte de dentro

14
00:00:25,449 --> 00:00:27,010
Ten pequenos células

15
00:00:27,010 --> 00:00:28,730
Que se chaman xanocite

16
00:00:28,730 --> 00:00:32,170
e unha cavidade interna chamada atrium.

17
00:00:32,689 --> 00:00:34,509
Son filtros filtrados,

18
00:00:35,310 --> 00:00:38,369
que filtra unha pequena organismo no agua.

19
00:00:38,789 --> 00:00:40,229
Poden ser de moitas colores

20
00:00:40,229 --> 00:00:42,170
e, nos antigos tempos,

21
00:00:42,750 --> 00:00:45,789
o esqueleto foi usado para a personalidade.

22
00:00:46,969 --> 00:00:48,509
As esponjas ten unha body

23
00:00:48,509 --> 00:00:52,070
suportada por estruturas de nido chamadas espiculas.

24
00:00:52,909 --> 00:00:55,210
As tres funciones de vitamina

25
00:00:55,210 --> 00:00:56,270
en periferia,

26
00:00:56,609 --> 00:00:57,590
a nutrición,

27
00:00:57,590 --> 00:01:01,509
They have no digestive system

28
00:01:01,509 --> 00:01:03,350
and they filter water

29
00:01:03,350 --> 00:01:05,489
to trap small organisms

30
00:01:05,489 --> 00:01:07,230
that water enters

31
00:01:07,230 --> 00:01:08,450
through the pores

32
00:01:08,450 --> 00:01:11,069
and the particles

33
00:01:11,069 --> 00:01:15,090
are trapped

34
00:01:15,090 --> 00:01:16,469
inside the atrium.

35
00:01:17,069 --> 00:01:17,989
Reproduction.

36
00:01:18,469 --> 00:01:20,269
They can reproduce asexual

37
00:01:20,269 --> 00:01:21,370
and asexual.

38
00:01:21,670 --> 00:01:22,290
Asexual.

39
00:01:22,370 --> 00:01:25,170
They reproduce asexual

40
00:01:25,170 --> 00:01:26,349
by biting.

41
00:01:26,349 --> 00:01:28,349
é similar a

42
00:01:28,349 --> 00:01:29,530
a transmisión, pero

43
00:01:29,530 --> 00:01:31,870
con unha pequena parte

44
00:01:31,870 --> 00:01:33,290
de beboide

45
00:01:33,290 --> 00:01:35,750
sexual, derrota da ducha

46
00:01:35,750 --> 00:01:37,670
sexual by gamete

47
00:01:37,670 --> 00:01:39,569
o male gamete

48
00:01:39,569 --> 00:01:41,750
se unha con a femenina

49
00:01:41,750 --> 00:01:43,150
e produza fertilización

50
00:01:43,150 --> 00:01:44,769
e crea unha nova

51
00:01:44,769 --> 00:01:46,329
interacción

52
00:01:46,329 --> 00:01:48,750
non ten individual

53
00:01:48,750 --> 00:01:51,090
células ou organismos

54
00:01:51,090 --> 00:01:54,049
que son especiales

55
00:01:54,049 --> 00:01:56,989
to detect environmental

56
00:01:56,989 --> 00:01:58,950
streams,

57
00:01:59,450 --> 00:01:59,750
like

58
00:01:59,750 --> 00:02:01,170
serms,

59
00:02:01,670 --> 00:02:02,329
mothman,

60
00:02:02,769 --> 00:02:04,030
darnex.

61
00:02:04,489 --> 00:02:07,090
However, they saw a number

62
00:02:07,090 --> 00:02:08,430
of small

63
00:02:08,430 --> 00:02:10,870
biobots

64
00:02:10,870 --> 00:02:11,689
that were

65
00:02:11,689 --> 00:02:12,569
responsible.

66
00:02:14,789 --> 00:02:16,710
The characteristics of medallions.

67
00:02:17,469 --> 00:02:18,669
They have radial symmetry

68
00:02:18,669 --> 00:02:20,870
and the most leafy in seas,

69
00:02:21,270 --> 00:02:21,889
oceans.

70
00:02:21,889 --> 00:02:24,689
They have a bug-shaped body

71
00:02:24,689 --> 00:02:27,270
They have a gastrovascular cavity

72
00:02:27,270 --> 00:02:29,050
That acts as a stomach

73
00:02:29,050 --> 00:02:31,550
Connected to the outside by holes

74
00:02:31,550 --> 00:02:34,090
Equally, they have tentacles

75
00:02:34,090 --> 00:02:36,409
A mouth that acts as both

76
00:02:36,409 --> 00:02:37,490
As anus

77
00:02:37,490 --> 00:02:39,770
They have felt

78
00:02:39,770 --> 00:02:41,870
Calles nidocites

79
00:02:41,870 --> 00:02:46,310
They use the tentacles

80
00:02:46,310 --> 00:02:49,090
To capture small platonic animals

81
00:02:49,090 --> 00:02:50,009
That they eat

82
00:02:50,009 --> 00:02:51,849
Two different forms

83
00:02:51,849 --> 00:02:52,889
Onidarians

84
00:02:52,889 --> 00:02:55,030
Polyps and jellyfish

85
00:02:55,030 --> 00:02:56,009
Polyps

86
00:02:56,009 --> 00:02:59,469
Live attached to a substrate

87
00:02:59,469 --> 00:03:01,069
Their back shape

88
00:03:01,069 --> 00:03:03,229
And their mouth is at the top

89
00:03:03,229 --> 00:03:04,629
Jellyfish

90
00:03:04,629 --> 00:03:06,169
Float around the sea

91
00:03:06,169 --> 00:03:09,849
Their bodies are like an umbrella

92
00:03:09,849 --> 00:03:11,650
And their mouth

93
00:03:11,650 --> 00:03:13,810
Is under the gastrovascular cavity

94
00:03:13,810 --> 00:03:17,990
The three vital functions

95
00:03:17,990 --> 00:03:19,189
Of Onidarians

96
00:03:19,189 --> 00:03:20,629
Nutrition

97
00:03:20,629 --> 00:03:26,349
O sistema digestivo do desnidario é moi complexo, mas tamén simples.

98
00:03:27,210 --> 00:03:29,669
Tén un sistema digestivo de un modo,

99
00:03:29,949 --> 00:03:36,830
un modo que significa que toda a comida, digestiva ou non,

100
00:03:37,750 --> 00:03:39,490
se passa do mesmo modo.

101
00:03:40,050 --> 00:03:43,129
Este proceso se chama cavidade gastrovascular.

102
00:03:44,150 --> 00:03:47,669
Usan células nos tentáculos para capturar a comida.

103
00:03:48,189 --> 00:03:49,110
Reproducción.

104
00:03:49,110 --> 00:03:54,830
They can reproduce asexually and sexually, the same as poriferous.

105
00:03:55,530 --> 00:03:56,250
Asexual.

106
00:03:56,669 --> 00:03:58,909
They reproduce asexually via body.

107
00:03:59,810 --> 00:04:05,449
It's similar to fragmentation, but with a smaller part of the body.

108
00:04:06,210 --> 00:04:06,610
Sexual.

109
00:04:07,250 --> 00:04:10,009
They reproduce asexually via gametes.

110
00:04:11,069 --> 00:04:18,370
The male gametes join with the female and produce fertilization and create a new one.

111
00:04:18,370 --> 00:04:19,810
Interacción

112
00:04:19,810 --> 00:04:21,689
Etnidáneos

113
00:04:21,689 --> 00:04:24,149
have a rudimentary

114
00:04:24,149 --> 00:04:25,250
nervous system

115
00:04:25,250 --> 00:04:27,889
Neurons are located regularly

116
00:04:27,889 --> 00:04:30,449
over the surface of the animal

117
00:04:30,449 --> 00:04:32,029
and like an egg

118
00:04:32,029 --> 00:04:33,850
they are in contact with

119
00:04:33,850 --> 00:04:36,410
dust nearest to it

120
00:04:36,410 --> 00:04:37,870
The effect of

121
00:04:37,870 --> 00:04:39,889
such an arrangement

122
00:04:40,490 --> 00:04:41,889
is then a

123
00:04:41,889 --> 00:04:42,750
stimulus

124
00:04:42,750 --> 00:04:46,029
Applied to any part of the animal

125
00:04:46,029 --> 00:04:47,490
will be directed

126
00:04:47,490 --> 00:04:48,990
a todos os planos.
