Egg-laying Mammals. There are only five living monotreme species: the duck-billed platypus and four species of echidna (also known as spiny anteaters). All of them are found only in Australia and New Guinea. Monotremes are not a very diverse group today, and there has not been much fossil information known until rather recently. In some ways, monotremes are very primitive for mammals because, like reptiles and birds, they lay eggs rather than having live birth. In a number of other respects, monotremes are rather derived, having highly modified snouts or beaks, and modern adult monotremes have no teeth.
The Ribbon contains multiple tabs, each with several groups of commands. You will use these tabs to perform the most common tasks in Excel. Each tab will have one or more groups. Some groups will have an arrow you can click for more options.
Microsoft Word has a function that shows you how many words your document contains. You can find this word count function under Tools, Word Count. This word count is not always correct, however, because Microsoft Word doesnât count the words that are contained in pictures or text boxes.
