Varying environmental climates require organisms to develop defense mechanisms to survive. For conditions under freezing temperatures, each animal has a response. If an animal is unprepared for the extreme situation, the formation of ice leads to a destruction of tissues and most organisms are unable to tolerate even frostbite; which make animals adapt to stay warm and out of the cold. Biochemical studies have examined why amphibians can tolerate freezing temperatures. Many amphibians, though…

. The 8 major systems within the body are the skeletal system, the nervous system, the endocrine system, the digestive system, the lymphatic system, the urinary system, the circulatory system and the reproductive system. Skeletal system - Bones make up the structure of our body, they are what gives it form. They are hard, and dense and interconnect via joints and are held in place by muscles and tendons. Bones are made of 25% water and 75% solids. the skeletal system protects and shields soft…

Discussion: Each test is a pertinent contribution to drawing an educated conclusion. After performing the gram staining and observing which unknown culture was gram positive, a catalase test was performed. The catalase test allows lab workers to differentiate Staphylococci and Streptococci genus. The test was performed only on the gram-positive culture. Bacteria that respire by the use of oxygen, otherwise known as aerobic respiration, produce enzyme or “catalase”. This protects the bacteria…

Sarah Omar Med 2049 Acute Renal Failure Instructor Michelle Earixson-Lamothe 08-01-2014 Humans have two bean shaped organs located just below the rib cage, one on each side of our spine known as kidneys. Every single day kidneys filter about 120 to 150 quarts of blood and produces around 1 to 2 quarts of urine. These fist sized organs are very important because they help to prevent the buildup of wastes, regulate blood pressure, help our bones to stay strong, makes red blood cells, and…

Proteins are known as the building blocks of cells in all living organisms. Many hormones are made up of proteins and the digestive system, immune system and blood replies on proteins. Therefore, protein is an essential part of healthy diet, and integral to development of the body. The purpose of performing this lab is to analyzing the activity of TEM-1 B-lactamase and how it reacts with high temperatures, chaotropic salts, detergents and pH values. INTRODUCTION: Primary protein structure is…

Throughout the semester in the microbiology lab we have been taught how to conduct multiple experiments to identify microorganisms. Many of these experiments can be used on all different types of microorganisms but cumulatively they can help isolate a singular microorganism’s identity. At the beginning of the semester we were divided into several groups and were assigned an unknown of which we were tasked with identifying. Being assigned number 14 as our unknown, my group consisting of…

Van Tran Microbiology Tuesday 5:00 May 5, 2015 Unknown Sample # 7 1. Introduction: Using biochemical tests are a good way to identify unknown bacteria from a sample. It is basically a similar to a trial and error method, but rather than using trial and error a person would be using positive and negative results. Using biochemical tests will help a person identify certain characteristics of the unknown bacteria through a series of chemical tests. Of course more than one biochemical tests…

But because they contain a lot of energy, amino acids are transported to the liver where they get the toxic amino acid group removed via deamination. The amino acid then forms the very soluble but highly toxic ammonium before being converted to urea and is then transported to the liver for excretion. There is some remaining keto acid which can be respired or converted to a carbohydrate or fat for storage. c. Describe the histology and gross structure of the liver Hepatic artery Supplies…

ALT, urea and creatinin. The pre test and post test of liver function test; AST and ALT done for the experiment of curry leaves group was highly significant (p< 0.001, paired „t‟ test). The mean score of the post test was less in AST and ALT as compared to the pre test. The assessment of the safety of curry leaf powder for renal function test; urea and creatinin in pre test and post test shown (Table. 7.2.) was highly significant (P< 0.001, paired t test).The post test mean score of the…

Solvent comprises a mixture of 30 ml deionized water and 10 ml of ethanol. To speed up the process of dissolution, the mixture was stirred using a magnetic stirrer for 30 minutes. The next process is to add the certain amount of urea catalyst to accelerate the reaction. Urea was added slowly to a solution of Zn(NO3) 3.4H2 O. Then, the mixture was stirred using magnetic stirrer for 30 minutes. Al dopant obtained from…
