When we hear the word medicine‚ doesn’t that imply it is a remedy to cure a sickness or disease? Medicine is used to restore our faith‚ hope‚ and most importantly‚ our lives. For hundreds of years‚ medicine has been known to cure many people including those who had barely an ounce of life left. However‚ as the Middle Ages progressed‚ medieval medicine became popular among people even though it was killing them instead of healing them. One example is the Black Death. As this horrible disease was

Diversity in Living Organisms (Science) |Close X | |[pic] Classification And Evolution Classification refers to the identification‚ naming‚ and grouping of organisms into a formal system based on similarities in their internal and external structure or evolutionary history. It determines the methods of organizing diversity of life on earth. Therefore‚ classification helps in understanding millions of life forms in detail. Who started the classification of organisms? Let us explore the history of

Classification of Living Things Classification of living things is called "Taxonomy." This is when scientists put organisms into groups when they have things in common. The first groups they use are the Kingdoms. There are five kingdoms: ➢ Animal Kingdom ➢ Plant Kingdom ➢ Fungi Kingdom ➢ Protist Kingdom ➢ Moneran Kingdom Each Kingdom is then split into smaller groups‚ called Phyla. Each Phylum is split into smaller groups called Classes‚ each Class is split into

the Chordata phylum. Chordates‚ the phylum which humans belong to‚ are characterized by their rod of stiffening tissue to support the body which has a nerve cord running alongside the rod – ending up by the brain. They would be closely related to Annelids and Arthropods but they have a dorsal nerve cord.

Animal Phylum Poster/Display Project Each student will select a major group of animals to research and ultimately create a poster or display to help explain the group of animals belonging to each class. Be sure to first read your textbook on the group as well as consult general resources before getting into specific resource materials. Students will be graded primarily on the content of the information as well as the creativity of the poster or display. The entire project is worth 75 points

There are many animals in the world. Some of them as small as ants and some are even bigger than elephants. These animals live throughout the world‚ some in the gigantic oceans‚ some in the coldest of Antarctica or some in the hottest of deserts. These are the classes of animals‚ mammals‚ amphibians‚ birds‚ reptiles‚ and insect. Reptiles are cold-blooded vertebrates. They have dry skin covered with scales or bony plates‚ and they usually lay eggs. Reptiles can be classified into three groups‚ turtles

Introduction Lumbriculus variegatus‚ or blackworms‚ are part of the segmented worms called annelids. The body is organized into repeated segments. It has a closed circulatory system‚ similar to humans because the blood is contained within blood vessels. Two major blood vessels‚ the ventral and dorsal vessels‚ run straight from the head to the tail‚ and several vessels connect the two in the anterior segments. The dorsal blood vessel acts similar to the heart‚ pumping the blood through wavelike contractions

The ability to regenerate body parts is a more challenging process but is shared by Planarians‚ Annelids‚ some amphibians‚ most lizards‚ and many arthropods. This characteristic has evolved in such a variety of species mainly through convergent evolution. It is difficult to establish clear rules for regeneration ability among a larger diversity of organisms
