Homeostasis

a very important role in maintaining the normal functions of the different, tissues, organs and organ systems in the body. It serves as the primary medium for carrying and transporting important gases, minerals and nutrients needed to maintain homeostasis. Blood is composed of several components: plasma, red blood cells, white blood cells and platelets. Plasma is the fluid compartment of the blood; it carries ions, minerals, nutrients, gases, hormones and antibodies. Ions and nutrients are…

The kangaroo rat can only survive in places hot and dry like a desert for example. The kangaroo rat can survive in the desert without ever drinking water. That's just some of the amazing facts that you will find in this paper The kangaroo rat is a rodent not a mammal people often get confused by its name they think it's in the kangaroo family. The kangaroo rat can jump up to nine feet, higher than any olympic high jumpers can jump that high. The kangaroo rat is in the animal kingdom and chordate…

1. What traits do most living things have in common? Most living things have to have energy in order to grow. They need food and water. Most living things have cells and DNA. They have to grow and reproduce. They have to maintain homeostasis. Most living things have to adapt and respond to their environment. 2.What is the difference between a non living specimen and one that you considered dead? I consider a non living item to be something that has never been alive. Examples of nonliving…

feedback loop will be helpful in maintaining homeostasis because if a male's testosterone levels are too low, then a positive feedback loop will increase them to maintain homeostasis. b) When you have too much oxygen, your brain sends signals to your body to exhale more often. you normally have about 98-99% of oxygen in your body, and when you have more than this, your body will use a negative feedback loop to decrease the levels of oxygen and maintain homeostasis. 14. The signal is the…

Our contemporary world faces many types of health related issues that seems to escalate and worsen as years go by. One of these problems is the global obesity epidemic. Over the last 30 years, obesity rate has doubled in the countries with a Western lifestyle. Throughout the years, there have been many suggested causes for obesity or weight gain. Current lifestyles, such as overeating and lack of physical activities, are the most prominent ones. However, there is one possible cause that is…

In the homeostasis, osmosis, and diffusion carrot lab, the mean growth in weight for the carrots soaked in solution A, one of our blue solutions, was 0.151 grams. Solution A had a standard deviation of 0.048. For solution B carrots, one of our clear solutions, the mean growth was 0.117 grams. Solution B had a standard deviation of 0.057. For solution C carrots, our other blue solution, the mean growth was negative, actually indicating a loss in weight. This mean loss was -1.426 grams. Solution C…

Elizabeth Barron Winters July 9th, 2017 Case study 1 Atkins or Fadkins Part 1: Macronutrients and energy Question 1: Proteins: do most of the work in the cells, required for structure, function, and regulation of the bodys tissues and organs. They also transport nutrients and are catalyst. Examples of proteins are nuts, meats, and beans. Carbohydrates: source of energy for the body, simple and complex carbs. Examples are fruits, pasta, sugar, and, grain. Fats: store energy, aid in…

my career development. 3. Dr. Rhadika Muzumdar, MD, Associate Professor of Pediatrics and Cell Biology, Chief, Division of Endocrinology at the Children’s Hospital of Pittsburgh of UPMC. Dr. Muzumdar has published widely on obesity and glucose homeostasis, will provide insight into the experimental design, anticipated outcome, and pitfalls. I meet with Dr. Muzumdar at least once every month to assess the lab performance, experimental results, and research progression. 4. Dr. Henry Dong, Ph.D.,…

Tetrahymena contractions with different solutions Purpose: How fast will the Tetrahymena contractile vacuole contract in different solutions? Introduction: In this experiment, the organism that is used are the Tetrahymena. The Tetrahymena has a contractile vacuole that protects them from absorbing too much water, causing cytolysis, in which a cell swells up and could result in explosion of the cell. The contractile vacuole expands when water enters it and contracts to release water to maintain…

one of the most complex. The integumentary system protects the body from the outside world and harmful substances. This system provides protection from the UV sun rays, while also providing vitamin D. The integumentary system provides temperature homeostasis that helps get rid of excess water through sweating and helps regulate our body temperatures. Some of the functions of the integumentary system are sensation, protection, thermoregulation, and secretion. For the cardiovascular system, it…
