Meiosis is a kind of cell division. It will lead to 4 daughter cells which each has only half of their chromosomes comparing to the parent. The end product has less chromosomes than the original that's why it's called reduction division.
Meiosis is important because the products are usually seen in gametes, which is sperms and eggs. If they get fertilized, they will form a zygote, and this is reproduction. Meiosis makes sure that the zygote has the right number of chromosomes, like half and half equals the correct amount chromosomes the organism should have. This also leads to diversity which is very important and a must in sexual reproduction.
Answer:
Modern amphibians are characterized by the flexibility of their gaseous exchange mechanisms. Amphibian skin is moistened by mucous secretions and is well supplied with blood vessels. It is used for respiration to varying degrees. When lungs are present, carbon dioxide may pass out of the body across the skin, but in some salamanders there are no lungs and all respiratory exchanges occur via the skin. Even in such animals as frogs, it seems that oxygen can be taken up at times by the skin, under water for example. Therefore, regulation of respiration occurs within a single species, and the relative contribution of skin and lungs varies during the life of the animal.
