2:Fish take the oxygen disolved in the water into their bodies through the gills.
These are filaments located on both sides of their head, protected by a gill cover
called the operculum (Water comes in through their mouth
passes to the gills and goes out again when the operculum 

3:the majority of fish are carnivore.

4: they are Oviparous.



How they breathe

Water transfers oxygen to the blood when it passes through the gills, and carries away carbon dioxide

2:Their limbs are fins that allow them two swim, change direction and maintain stability in the water.

3:Their bodies are smooth, fusiform, and covered with scales.

4: backbone]]> 2022-03-09 08:46:15 UTC https://padlet.com/antoniomoral/Bookmarks/wish/2085643295 antoniomoral https://padlet.com/antoniomoral/Bookmarks/wish/2085654283  Bony fish, as the name implies, have a skeleton built completely of bones, whereas cartilaginous fish have a skeleton made entirely of cartilage (cartilaginous fish), such
as sharks; others have a skeleton
made of bone (bony fish). These two
groups make up the majority of fish.
In cartilaginous fish, the gills open
directly to the water. In bony fish,
the gills are protected by a cover
(operculum).

1: They are tetrapods (from tetra 'four' and podos, 'feet). Their limb support them on the ground sow they can move

2:They have thin, moist skin. A sticky mucus produced by glands under their skin helps them stay moist.

3: they have backbone]]> 2022-03-09 09:28:26 UTC https://padlet.com/antoniomoral/Bookmarks/wish/2085704829 antoniomoral https://padlet.com/antoniomoral/Bookmarks/wish/2085727911
1:They are cold-blooded. Temperature changes according to the enviroment.

2: they breathe through their moisty skin ( alsow lungs).

3:the majority of amphibians are carnivores; tadpoles, however are herbivores.

4: they are oviparous: they lay their eggs in water. The eggs in water.]]> 2022-03-09 09:43:42 UTC https://padlet.com/antoniomoral/Bookmarks/wish/2085727911 antoniomoral https://padlet.com/antoniomoral/Bookmarks/wish/2085733481 Metamorphosis is the developmental process some animals go through from birth
to adulthood as they grow.
In the case of frogs, tadpoles are aquatic animals and herbivores. They undergo
significant changes as they develop until they become
adult amphibians.]]> 2022-03-09 09:47:05 UTC https://padlet.com/antoniomoral/Bookmarks/wish/2085733481 antoniomoral https://padlet.com/antoniomoral/Bookmarks/wish/2086814580 1: Their scaly skin is tough and dry.
They have scales made of keratin
that protect them from dehydration
and injury.

2: They are tetrapods. Their legs are adapted
for walking, climbing or swimming.

3: they have a backbone]]> 2022-03-09 19:43:42 UTC https://padlet.com/antoniomoral/Bookmarks/wish/2086814580 antoniomoral https://padlet.com/antoniomoral/Bookmarks/wish/2086819050 They are ectothermic or cold-blooded animals.
•They breathe through lungs.
• Many reptiles are carmivores and hunt their prey. Some reptiles have glands
with poison that they use to paralyse their prey before they swallow it.
• They are oviparous. Their eggs, which can be leathery or hard-shelled, contain
a series of sacs that provide food and protection to the embyro. One of these
sacs, the amnion, is filled with liquid in which the embyro develops. Eggs with
an amnion are called amniotic eggs.]]> 2022-03-09 19:46:10 UTC https://padlet.com/antoniomoral/Bookmarks/wish/2086819050 antoniomoral https://padlet.com/antoniomoral/Bookmarks/wish/2086877960 2022-03-09 20:27:24 UTC https://padlet.com/antoniomoral/Bookmarks/wish/2086877960 antoniomoral https://padlet.com/antoniomoral/Bookmarks/wish/2086907050 1: They do not have teeth; instead
they have a strong beak.

2: They have feathers on their
bodies and scales on their legs.

3:They are bipeds; their front limbs
have become wings.

4: Their bodies are fusiform and their
necks are usually long.

5: they have backbone]]> 2022-03-09 20:48:08 UTC https://padlet.com/antoniomoral/Bookmarks/wish/2086907050 antoniomoral https://padlet.com/antoniomoral/Bookmarks/wish/2086912154 • They are endothermic (from endo, "inside' and thermo, 'heat'). They are able to
produce and maintain their own heat to keep a constant body temperature,
regardless of the temperature of their environment.
• They breathe through lungs.
• Their eating habits are varied and related to the size and shape of their beaks.
• They lay amniotic eggs with hard shells, so they are oviparous.]]> 2022-03-09 20:52:24 UTC https://padlet.com/antoniomoral/Bookmarks/wish/2086912154 antoniomoral https://padlet.com/antoniomoral/Bookmarks/wish/2086914544 2022-03-09 20:54:31 UTC https://padlet.com/antoniomoral/Bookmarks/wish/2086914544 antoniomoral https://padlet.com/antoniomoral/Bookmarks/wish/2086922507 1:They have different kinds
of glands, such as the ones
that secrete sweat and oily substances.(milk)

2:Mammals are tetrapods.
Terrestrial mammals have
legs; marine mammals,
fins; and flying mammals,
wings as front limbs.

3: Their body is covered by hair or
fur, a good thermal insulator that
also protects them from humidity.

4: they have a backbone




Humans

• We have little hair on our bodies. It is only plentiful in certain areas, such as our
nead
• Females develop mammary glands, which are located in the breasts.
• Our skin has many swe at glands. Sweating helps us reduce our body temperature.
• We walk on our two back limbs, our legs; we are bipeds. Our front limbs are,
therefore, free to carry out other functions.
• The size of the human brain is very large in comparison to the size of the human
body.
• We communicate with individuals of our own species and we are able to learn.

•They breathe through their lungs.
• Mammals have very varied eating habits. They can be herbivores, carnivores or
omnivores.
They are viviparous, which means that they give birth to young already developed
inside the mother (in a shelless, amniotic egg) and nourished through the placenta.
• They have a very developed nervous system.]]> 2022-03-09 21:21:27 UTC https://padlet.com/antoniomoral/Bookmarks/wish/2086946856
