I repeat, 11, 4. Okay, and then you need to fold it 5 times. 1, 1, 2, 3, 4, 5. 17 00:02:04,640 --> 00:02:11,439 Be careful because the last one, we need to leave two centimeters here, okay? 18 00:02:12,360 --> 00:02:20,800 And when you finish folding, it is when you have to cut this part, okay? 19 00:02:21,060 --> 00:02:24,280 Don't do it until you don't finish with the foldings. 20 00:02:24,479 --> 00:02:32,060 I suppose you have finished with your flaps, so you should have something like this, more or less, okay? 21 00:02:32,060 --> 00:02:40,219 with these two centimeters that on this part is what we're gonna glue on our notebooks, oh sorry 22 00:02:40,219 --> 00:02:47,080 notebooks, no, lab books, okay, but wait until we finish writing all this information here, okay, 23 00:02:47,080 --> 00:02:54,919 so when we have folded, look, I have a small part here on the front, I write characteristics of 24 00:02:54,919 --> 00:03:02,360 vertebrates, okay, characteristics of vertebrates, that's what I write here, okay, since we're going 25 00:03:02,360 --> 00:03:09,500 to glue it on our notebook like this, okay, that's why I wrote in this direction, and also 26 00:03:09,500 --> 00:03:17,939 I have uploaded in Diabla Virtual these pictures, okay, we are going to use the first two rows, 27 00:03:18,419 --> 00:03:24,599 okay, here, it will appear on the right part of the screen, the picture that you need to 28 00:03:24,599 --> 00:03:32,439 glue on each of the squares. Let's start with the characteristics. So, the first one, and the one 29 00:03:32,439 --> 00:03:39,219 why we are called vertebrates, is because we have internal skeleton. We have an skeleton inside our 30 00:03:39,219 --> 00:03:45,919 body, which are the bones. Basically, all vertebrates have backbones, okay? The backbones 31 00:03:45,919 --> 00:03:52,639 are the ones that we have here at the back. Okay? And we have here that picture. Great. 32 00:03:53,280 --> 00:04:01,039 Then, nervous system. We have a nervous system consisting of the brain and the spinal cord that 33 00:04:01,039 --> 00:04:10,960 also goes on the back of our body inside our backbones. And the picture is that our skin 34 00:04:10,960 --> 00:04:17,360 and the skin of all vertebrates is for sensation and protection. You can see beautiful scales 35 00:04:17,360 --> 00:04:24,720 all the snakes. We have a closed circulatory system. In invertebrates we have both an open 36 00:04:24,720 --> 00:04:29,279 and closed circulatory system, but all the vertebrates have a closed circulatory system. 37 00:04:31,839 --> 00:04:39,279 And finally we have sexual reproduction, usually with separate sexes. It's true that some fish can 38 00:04:39,279 --> 00:04:45,220 be hermaphrodites. But most of the animals, most of the bird breeds have 39 00:04:45,220 --> 00:04:54,540 separate sexes, like chicken and hen. Okay? So let's work!
