Hello boys and girls, welcome to a new natural science lesson. In this case you need two
00:00:00
vertebrates
00:00:07
lesson two vital functions
00:00:08
mirror world
00:00:12
vital functions
00:00:15
Vertebrates perform three vital functions
00:00:17
Do you remember the name of the three vital functions?
00:00:23
Number one is nutrition
00:00:28
Number two reproduction
00:00:31
Number three interaction
00:00:35
Mirror world
00:00:39
nutrition
00:00:41
reproduction
00:00:43
interaction
00:00:45
Next the first one is nutrition
00:00:49
Carnivores eat other animals
00:00:54
Remember their teeth are long and sharp
00:01:01
One example of a carnivore is the lion
00:01:07
Herbivores eat plants
00:01:14
their teeth are
00:01:18
Short and flat
00:01:21
One example of a herbivore is the zebra
00:01:23
Then we have a third type of vertebrates in terms of nutrition
00:01:29
omnivores eat
00:01:35
both
00:01:38
animals and plants
00:01:40
One example of omnivores is the wild boar
00:01:42
Reproduction that is the vital function number two
00:01:47
mirror world
00:01:51
viviparous animals give birth to live babies
00:01:55
Humans are viviparous too
00:02:02
As you can see
00:02:07
There is a human mother with a human baby or fetus inside her womb
00:02:10
Let's continue the second type of
00:02:17
vertebrate in relation to
00:02:22
reproduction are
00:02:25
all-viparous animals
00:02:27
Remember mirror world
00:02:29
all-viparous animals lay eggs
00:02:31
Some like frogs lay many many eggs
00:02:38
Others like birds lay a few eggs
00:02:43
Next
00:02:51
We have a third type of
00:02:53
vertebrates if we speak about reproduction
00:02:57
mirror world
00:03:00
in
00:03:02
all-viparous animals the eggs
00:03:04
grow and hatch
00:03:08
Inside
00:03:11
their mother's body
00:03:13
so in this case
00:03:16
So in this case, we are mixing a little bit of viviparous animals and a little bit of
00:03:18
all-viparous animals
00:03:24
some examples of all the viviparous animals are
00:03:26
Platypus, which is a mammal that seems like a duck
00:03:30
Manta ray and guppies that are fish
00:03:35
Remember in this case the eggs
00:03:40
grow inside the mother and also hatch
00:03:43
inside the mother
00:03:48
next
00:03:50
the third vital function is
00:03:52
interaction and we will divide it in two
00:03:55
interaction one and interaction two
00:03:58
interaction one
00:04:02
mirror world
00:04:04
animals live
00:04:07
alone in groups or in large communities
00:04:09
First rhinoceros or polar bears live alone
00:04:18
On the other hand
00:04:25
zebras or sheep
00:04:28
live in groups or herds for protection and
00:04:30
the third case
00:04:37
Prairie dogs or ants live in large communities
00:04:39
Remember ants are just an example of large communities, but they are not
00:04:45
Vertebrates they are
00:04:51
Invertebrates we will learn that in unit number three
00:04:53
Next the second type of interaction relates is related to
00:04:57
animals which use different parts to move around
00:05:03
mirror world
00:05:08
Turtles use their legs to swim
00:05:12
On the other hand tortoises cannot swim. They are terrestrial
00:05:16
Eagles
00:05:22
Use their wings and feathers to fly
00:05:25
On the other hand hens cannot fly. They just walk around
00:05:30
Horses use their legs to walk and run
00:05:39
Monkeys use their arms and legs to climb
00:05:46
Remember that you can find all this information
00:05:52
In your outlines in your notebook in this lab book. Thank you very much for listening
