Mammalia - Profile of Class Mammalia

Mammalia - Profile of Class Mammalia The Class Mammalia is comprised of animals known as mammals. Description: Mammals represent a wide range of shapes, sizes and colors. One characteristic of all mammals is that they have hair. This is more obvious in some animals, such as seals, who often have visible fur, than in others, like whales, whose hair has sometimes disappeared by the time they are born. Speaking of birth, just about all mammals (except the platypus and echidna) give birth to live young, and they all nurse their young. Mammals are also endotherms, commonly known as warm-blooded. Classification: Kingdom: Animalia Phylum: Chordata Class: Mammalia Habitat and Distribution: Mammals are distributed worldwide, in a variety of habitats. Marine mammals range from coastal areas (e.g., the manatee) to the pelagic zone (e.g., whales), with some, such as sea turtles and seals, even venturing into the deep sea to feed. Feeding: Most mammals have teeth, although some, like the baleen whales, do not. Since mammals range widely in habitat and food preferences, they have a wide range in feeding styles and preferences. In marine mammals, whales feed using teeth or baleen, and on a variety of prey, including small fish, crustaceans and sometimes other marine mammals. Pinnipeds feed using teeth, usually eating fish and crustaceans. Sirenians also have teeth, although they also use the power of their strong lips when grasping and ripping aquatic vegetation. Reproduction: Mammals reproduce sexually and have internal fertilization. All marine mammals are placental mammals, meaning they give birth to live young, and the unborn young are nourished in the mothers uterus by an organ called the placenta.

Mandarin Chinese Sentence Structure

Mandarin Chinese Sentence Structure Mandarin Chinese sentence structure is quite different than English or other European languages. Since the word order doesnt match, sentences which are translated word-for-word to Mandarin will be difficult to understand. You must learn to think in Mandarin Chinese when speaking the language. Subject (who) Just like English, Mandarin Chinese subjects come at the beginning of the sentence. Time (when) Time expressions come immediately before or after the subject. John yesterday went to the doctor.Yesterday John went to the doctor. Place (where) To explain where an event happened, the place expression comes before the verb. Mary in school met her friend. Prepositional Phrase (with whom, to whom etc.) These are phrases which qualify an activity. They are placed before the verb and after the place expression. Susan yesterday at work with her friend ate lunch. Object The Mandarin Chinese object has a great deal of flexibility. It is usually placed after the verb, but other possibilities include before the verb, before the subject, or even omitted. Conversational Mandarin often omits both the subject and the object when the context makes the meaning clear. I like on the train read the newspaper.
