Male and female turtles
The turtle is a reptile characterised by having a wide, short trunk, and a shell that protects the internal organs of the body. Coming out of the shell are: the head and front legs, and behind, the hind legs and the tail.
The most important characteristic of the skeleton of turtles is that a large part of the spinal column is welded to the back side of the shell.

 The skeleton makes breathing impossible by movement of the rib cage si it is performed primarily by the contraction of the modified abdominal muscles. The skull has great features of primitivism.
Although lacking teeth, they have a beak covering its mandible, like the beak of the birds.
 Like all reptiles, turtles are ectothermic, which means that their metabolic activity depends on the external or temperature of the environment.
Turtles shed their skin, but unlike lizards and snakes, they do it gradually. They also molt the shields of the carapace, individually and apparently in no particular order.

Check out this interesting video about the origin of the atom structure theory. The study of atoms has changed from thinking that  atoms are static particles, to then finding that the electrons move around the atoms, now it is known that electrons do not follow the laws of motion and that the movement of electrons is unpredictible.

 Here is a list of elements and their symbols that you studied last year. It is convenient that you revise them again this year. Most elements have very similar names in spanish and in english but I have written next to the ones that differ a little more, the name in spanish too. You must study them for the next grade exam.

Go to the articles section to watch a really interesting video about the origin of the atom theory!
