...Student Sheet Name: Herginaldo Felix Date: 06/25/2015 Instructor’s Name: Kayla Robinson Assignment: SCIE207 Phase 4 Lab Report Part 2 Title: Exploring Endocrine, Circulatory, and Respiratory Systems Instructions: Your lab report from Part 1 along with the Part 2 activity will serve as a guide to answer the questions and to complete the tables for the endocrine, cardiovascular (circulatory), and respiratory systems. When your lab report is complete, submit this document to your instructor in your assignment box. 1. Endocrine System Question 1: How does the insulin and glucagon secreted by the pancreas function in glucose metabolism? Answer 1: Insulin and Glucagon work in tandem to keep the glucose levels in the blood within the normal range. If someone if experiencing high blood sugar levels, the pancreas will begin to secrete insulin by way of the beta cells. As this is happening the liver will take up the glucose and store it as glycogen. Now in the reverse, if a person is suffering from hypoglycemia and has low blood sugar, the alpha cells located inside of the pancreas will begin to produce glucagon. This substance will be sent to the liver and begins the process of converting glucagon to glucose. 2. Cardiovascular System Blood flows through the body in two distinct pathways: the pulmonary pathway and the systemic pathway. The blood flowing in the pulmonary pathway is deoxygenated, and it delivers this blood to the...

...Student Sheet Name: AMALISE CUBERO Instructor’s Name: Assignment: SCIE207 Phase 1 Lab Report Title: Understanding the Scientific Method: Photosynthesis and Cellular Respiration Instructions: Based on the virtual experiment, you will answer some questions and write a 1-page lab report using the scientific method. When your lab report is complete, submit this document to your instructor in your assignment box. Using what you learned on the lab animation, answer the following questions: • Define a hypothesis that is suggested by the data that are collected in the lab. It was predicted that the intensity of light exposure that was given to the Pacific Ocean’s Seaweed, will increase the rate of photosynthesis however none the less but at a specific moment of exposure it will not yield to a quicker process. The goal is to figure out what moment in time this would be and if this is a repeatable conducive. • What effect does the intensity of light have on the rate of photosynthesis (measured as the number of oxygen bubbles)? • The Hypotheses given in the lab shows the increase in light concentration, an accelerated photosynthesis process went on with the 0-watts to 100-watts. The average number of bubbles in the 0 watt study was 2 bubbles in 1 hour. After the increase of a 25 watts had went up to 5 bubbles in the 1hour. With the increase of another 25 watts equaling to 50 watts now the number of bubbles increased once again to 11 bubbles...

When your lab report is complete, submit this document to your instructor in your assignment box. 1. Endocrine System Question 1: How does the insulin and glucagon secreted by the pancreas function in glucose metabolism? Answer 1: “Insulin and glucagon work together to keep glucose levels in the blood within the normal range. When there is an elevated blood glucose level, this stimulates beta cells in the pancreas to secrete insulin. The insulin facilitates the uptake of glucose by body cells, and the liver will uptake the glucose and store it as glycogen. These actions return blood glucose levels back to normal. When there is decreased blood glucose, this stimulates the alpha cells in the pancreas to produce glucagon. The glucagon travels to the liver and facilitates the conversion of glycogen to glucose. This glucose is released in the bloodstream to return levels back to normal.” (M.U.S.E.) 2. Cardiovascular System Blood flows through the body in two distinct pathways: the pulmonary pathway...
