My species is Pangasius Sanitwongsei, and it forms part of the shark catfish family, which supposedly appeared about 70 million of years ago. Scientifics identifies the specie because of the presence of six branched pelvic fin rays, two maxillary barbels, and two mandibular barbels. It's proven that in the past Pangasius Sanitwongsei crossed the barrier between Africa and Asia, and this specie is originally from Asia but it got introduced to other places, it's actually considered a migratory specie. My species has an extraordinary diversity and distrivution patterns based on their long evolutionary process, and the Africa's P. Sanitwongsei is actually bigger than the Asian one. Pangasius Sanitwongsei come from Pangasiandon Hipophthalmus, which formed other species from the Pangasius family. My specie didn't used to be an endangered specie and they also have no natural predators, but due to overfishing their population started decreasing until they became an endangered specie. (The internet couldn't provide all the information I needed but I've put the most important things I found)

I selected Daniela's padlet because she has the same name a close friend of mine has. The content is perfectly understandble, it's very organized, it would be difficult to get lost because she organizes her sentences and marks the most important things. Her padlet looks and it's professional, the background feels really nice to sight, everything looks perfect.

I selected the specie I selected because I like fish species in general, I thought the specie looked cool, and the name sounded really interesting to me. Climate change will make Giant Pangasius witness longer flood seasons, larger inundation areas, sea level rise, and temperature change. Apart from temperature change, there has been a drop in average rainfall, and drought season too, it's also expected to increase the salinity level of their environment. None of these things are good for Pangasius Sanitwongsei, and more because too much salinity in the water can be really bad for this specie, and temperature changes are not good in general for sea species.

There is active transport and passive transport in the cell membrane, active transport requires energy called ATP but passive does not. Passive transport it's basically the movement of things passing the plasma membrane down the concentration gradient, it does not need the energy of ATP because it already goes with the flow. Passive transport "goes with the flow" because the movement of substances moves from being in an area that has a high concentration to another one with a low concentration. There are three types of passive transport which are: osmosis, diffusion, and facilitated diffusion.

ATP is a source of energy present in all cells, it's made of a nitrogenous base, a ribose sugar, and three phosphate groups. There is another source of energy too which is created in an anaerobic way called ADP but it provides very low energy compared with ATP. This high-energy provider can help with the transportation of cells, circulation, body movements, and locomotion. Adenosine triphosphate is located and produced at the mitochondria because cellular respiration takes place there but in plants, it also exists in the chloroplast.

The cell membrane it's a membrane that exists in all kinds of cells (eukaryotic and prokaryotic) and covers all the cells separating the outside from the inside. Its function it's to choose what can go in and out of the cell, not everything can go in and out but it also helps with cellular transport. It's made of two layers of phospholipids and proteins, phospholipids also have a side that is hydrophobic, and the other side that is hydrophilic.

Something that caught my attention is that the process shown in the video helps larves and adults from competing for space and food sources. Something else that caught my attention too is that the specie is already born with the cells that they need to become butterflies, I could never imagine something like that before.

One idea that caught my attention form one of today's mini lectures were cells, specificly the cell membrane because it decides what can go inside the cell and outside the cell. It was also very interesting how the algae could be an unicellular organism but had more than one nucleous, it felt like if there were more than one cell there but all together.

Pangasius Sanitwongsei is a type of fish that can be found mainly in Chao Phraya and Mekong basins in Indochina but it can be also be found in Vietnam, , Laos, Cambolia, Thailand, and China, this fish it's also been introduced to Anatolia, South Africa, and Malaysia. The Giant Pangasius specie is not tolerant to cold waters and can grow well in salinities up to 13 ppt. These fishes are tolerant to poor quality water, they live in rivers, in fact the Pangasius Sanitwongseis specie prefers to live in the bottom of deep depressions in freshwater rivers. They live in rivers but they are in danger too, this is due to dams being built there, it makes them unable to migrate because they are trapped. They are canivorous and eat mostly shrimps, crabs, and other fishes because they live in the bottom of the rivers, they can also eat larger animal's carcasses.

In the "When is pandemic over?" I have learnt lots of things about ways of stopping a pandemia, it remind me of Covid-19 times. There are three main ways of dealing with a pandemia, which are: Race Through It, Delay & Vaccinate, and Coordinate & Crush. To race through the pandemia is literally doing nothing with it, letting the virus spread, letting people die, until everyone stops getting affected and infected by it on their own. To delay and vaccinate means to slow the spread and testing with the virus tp create a vaccine, there are many ways of slowing the spread, some of them are quaranteen and social distance. Delay and Vaccine is the most helpful method and it's also the one that it's used more often. The last method is  to coordinate and crush, which tries to stop the virus simultaniously everywhere by a convination of quaranteen, social distancing, and restricting travel, but all the countries should agree at the same time to make it work, and the virus would problaly still spread slowly. In my opinion, the video was really interesting and I enjoyed learning about this topic.

Giant Pangasius are fish of freshwater that has been on the red list of threatened species since 2007 by the IUCN. Their habitat and ecology exist in Wetland (Inlands) and they come from the Pangasiidae family which is also called the Shark Catfish family. Gian Pangasius population has decreased a lot over time and now they are considered critically endangered, this drastic decline is due to overfishing. Humans are actually the only predators this specie has because they have no natural predators either.

I think that the information in the video can be really helpful in real life, some people think that they can say false things about other people like if nothing happened, but I think that lots of things should always have an evidence. When you are with your friends and you have a claim about something that happened, it's important to have the evidence and connect the dots of the story using the reasoning. This would also be very helpful because it demonstrates people that what you are saying is the truth because Claim, Evidence, and Reasoning can be used in lots of ways. Using this method in our daily life would be a very positive thing, I think dealing and understanding people would be easier and would made us learn more about our enviorement. Another example, if my family had a discussion you can help them solve it easier and bring them a good reasoning with a good conclusion, if I used it with friends it would help me know them better.

Hi, my name is Samantha Maria Rojas Parellada but I prefer to be called just Mar, I'm a dual enrollment student, I go to high school and at the same time I have college classes, right now I'm a sophomore so I'm 15 years old for now but I will turn 16 on my birthday, which is on June 21. I'm from Barcelona, I lived there most of my life, I got to this country about 9 months ago but I lived a year in South Carolina when I was 11 years old, I like my school but I prefer holidays. My biggest hobby is drawing, I love to draw but I don't see myself as an artist in the future, I would like to be a dermatologist or an actor, I like to cook sometimes too but I prefer to eat the food, and more if it's chocolate because I think that is my favorite food. Something else that I like that I don't think that is considered a hobby is talking with people, I love to hear things about them and expressing what I think. Personally, my favorite place to live was my city but I will problaly move to Orlando when I grow up. I have been a good student most of my life so my goals are always to get perfect grades, or at least trying my best, getting an A here is easier than in Spain, for example: 3 years ago I used to study things in my country that juniors in my school are studing now, I also speak 3 languages: Spanish, English, and Catalan, I was learning German 4 years ago but I forgot everything, and I would also like to learn Corean in a future, but for now, the most important thing for me are my studies and my friends.
