The discover of cows is very important because now we can milk them for milk and use them to make many things and we also kill the cows for food. There are not many bad things about cows except that the bring a lot of mosquitos.

Constantine John Phipps was the first to describe the polar bear in 1744 but no one knows when the polar bear was really discovered. The discovery of polar bears are important to the marine life and they are also important to the arctic people. Polar bears are one of the signs of the health of the eco system.

Penguins average height is 110cm - 120cm and their average weight is 22.7 - 45.4 kg depending on the gender. Penguins are an advantage to the zoo because it attracts people to the zoo and it brings the zoo a lot of money penguins are also an important part of the food chain they fertilize the landscape with things like nitrogen. Without penguins many  other animals will be extinct because they are the prey of many animals like leopard seals polar bears these animals eat penguins and their eggs to stay alive. The bad thing about penguins being discovered is that we are keeping them in a zoo and they aren’t able to do what they normally do because we are interrupting them by doing research or measuring their height or taking pictures of them. I think the discovery of emperor penguins were good because they help us do many things for the food chain and they also bring us entertainment .]]> 2021-10-07 01:01:47 UTC https://padlet.com/wongh372/p8pzdenbancyrxan/wish/1798188549 1767 wongh372 https://padlet.com/wongh372/p8pzdenbancyrxan/wish/1801249406 The Pomeranian was discovered by queen-consort of King George III in 1767, the average height of an Pomeranian is 7 to 12 inches tall and the average weight is 3 to 7 pounds for adult. Pomeranians are very important to humans because they give emotional support and could be apart of a family to. The bad thing about the discovery of Pomeranians is that almost where ever they go they will always pee or poo everywhere. ]]> 2021-10-08 00:54:06 UTC https://padlet.com/wongh372/p8pzdenbancyrxan/wish/1801249406 1957 wongh372 https://padlet.com/wongh372/p8pzdenbancyrxan/wish/1801297827 the first space ship was invented in 1957 by NASA, the first spaceship was 4,500,000 pounds and 184 feet tall. the space ship was launched into space on 1957 and landed successfully on back on earth in 1961. The good thing about spaceships is that, they have made many discovery's in space they have done many tests and now we have a lot of information about space and many of our questions have been answered by doing this we also had the satellite launched with the first space ship. The bad thing about the launch of the first space ship was the amount of pollution that was released. ]]> 2021-10-08 01:16:17 UTC https://padlet.com/wongh372/p8pzdenbancyrxan/wish/1801297827 sources wongh372 https://padlet.com/wongh372/p8pzdenbancyrxan/wish/1822703891 cows: https://www.livescience.com/28154-new-world-cattle-origins.html#:~:text=The%20first%20cows%20brought%20to,a%20new%20genetic%20analysis%20shows. https://www.dimensions.com/element/holstein-friesian-cattle#:~:text=The%20average%20Dairy%20Cow%20has,farm)%3B%2020%20(natural).
