TOPIC : Frogs NARROWED FOCUS : Species of Frogs THESIS : There are over 4‚000 species of frogs but our focus will be limited to the Poison Dart‚ Wood and Darwin Frogs‚ which all belong to the Ranidae family. INTRODUCTION : Frogs belong to a group called amphibians which begin their lives in the water as eggs and then tadpoles and when fully developed they live on land. Three distinguishing elements such as: their habitat‚ size and the reason for the names given to them will be highlighted

1. Discuss the relationship between distribution of muscle fiber type and performance. How might exercise training modify or change a person’s fiber-type distribution? Skeletal muscles contain multiple fiber types that are distinguished by their different myosin ATPase speed‚ and the development of their SR. The two main fiber types are type I and type II fibers. Type II fibers have a faster ATPase and a more developed SR than type I fibers. Type II fibers are also part of a larger motor unit‚

Intramembranous ossification forms membrane bone from fibrous connective tissue membranes‚ and results in the cranial bones and clavicles. ~Movements of Muscle~ 1) Flexion: bending a joint to decrease the angle between two bones or two body parts. Bending the elbow‚ or clenching a hand into a fist‚ are examples of flexion. When

Currently‚ frog populations around the world are declining. Due to the nature of their life cycles and physiology‚ frogs are very sensitive to environmental changes. Frogs are born in the water as tadpoles. Frogs move onto land for their adult lives. This makes them vulnerable to changes in aquatic habitat availability. This also makes them vulnerable to changes in terrestrial habitat availability. Their aquatic habitats are drying out‚ in areas that are becoming more prone to drought. Frogs are also

Muscles attached to scapula: Levator scapulae origin is transverse processes of C1-C4‚ insertion at superior angle of scapula‚ it moves scapula and flexes neck. Pectoralis minor’s origin is ribs 3-5 and insertion at coracoid process of scapula‚ it depresses scapula and elevates ribs. Rhomboids Major and Rhomboids Minor’s origin at spinous processes T1-T4‚ insertion at medial border of scapula‚ they move scapula. Serratus anterior’s origin is at ribs 1-9‚ insertion is at medial border of scapula

Disney’s Heroines from The Little Mermaid to The Hunchback of Notre Dame By Celeste Lacroix argues consumerism and orientalization is rife throughout Disney princess movies. I disagree‚ and through my analysis of the Disney movie The Princess and the Frog I will prove that not all Disney princess movies are racially biased and portray woman as helpless creatures who need a man’s guidance. In Lacroix’s article she uses Disney movies such as Beauty and The Beast‚ The Little Mermaid‚ Aladdin‚ Pocahontas
