Enzymes in Living Tissues Purpose: The purpose of the lab was to analyze the enzymes in living tissues‚ represented by the pieces of liver. Also‚ hydrogen peroxide was used to demonstrate these effects. Storyboard: Materials: 2 50 mL beakers 10 mL graduated cylinder 3% hydrogen peroxide solution Hot water bath Lemon juice or HCl Fresh liver Forceps Procedure: Measure 10 mL of hydrogen peroxide and record its temperature. Pick the liver up with the forceps and

vascular plants‚ phloem is the living tissue that carries organic nutrients‚ particularly sucrose‚ to all parts of the plant where needed. (Lalonde S‚ 2004) Phloem’s main job is to move sugars from the source tissue (ex. photosynthetic leaf cells) to sink tissues (ex. non-photosynthetic root cells or developing flowers). Molecules like proteins and mRNAs also are transported to parts of the plant by the phloem. (WiseGEEK) Phloem is composed of several cell types including sclerenchyma‚ parenchyma

List the 4 primary tissue types and give the general characteristics and functions of each one. Epithelium- The epithelium protects us from the outside world. Skin‚ absorbs. Stomach and intestinal lining‚ filters. The kidney‚ secretes. Forming of glands‚ closely attached to each other forming a protective barrier‚ always has one free surface open to outside the body or inside an internal organ‚ has no blood vessels but can soak up nutrients from blood vessels in connective tissue underneath‚ always

Anatomy-Physiology 1 Exam 2 Study Guide‚ Chapters 5 & 6 There are only four primary tissue types found in adult organs; epithelial‚ connective‚ nervous‚ and muscular tissue. Epithelial tissue lines body cavities‚ covers the body surface‚ and forms the lining of many organs. Connective tissue serves in most cases to bind organs to each other. Nervous tissue and muscular tissue are considered excitable tissues because they are very sensitive to outside stimuli. A simple epithelium consists of

1. Explain the differences between Diabetes mellitus Type I vs Type II. Are there any other forms of diabetes? Type 1 diabetes is insulin dependent‚ an autoimmune destruction of beta cells in the pancreas. Therefore‚ required insulin replacement‚ and not associated to obesity‚ and occur mostly in children and adolescent. However‚ type 2 diabetes it is non- insulin- dependent‚ and caused by decreased of insulin production‚ and occur mostly in people 50+ age‚ and associated with obesity. 2-What are

glucose due to either the pancreas not being able to generate insulin or the cells not reacting to the reduced amount of insulin being produced‚ these are diagnosed as type 1 and type 2 respectively. Carol is the case study being used‚ she was diagnosed with type 1 diabetes at the age of 7 and she is also 6 weeks pregnant. As type one diabetes is an autoimmune disease the immune system is malfunctioning‚ so when the patient is exposed to a virus the bodies’ reaction can be more severe than that

Unit TDA 2.5: Schools as Organisations Task 1 1.1 Identify the main types of state and independent schools All children aged 5-16 are entitled to a free place at a state school and most families take up this place. Schools across England are funded and managed in different ways and will vary depending on the age of the child. There are four types of mainstream state schools funded by local authorities which are known as maintained schools. They all follow the National Curriculum and are inspected
