Homeostasis is a system that regulates internal environment and tends to maintain a stable and constant condition‚ it is normally found within living organisms. It receives and sends information about the body’s condition to the hypothalamus which can then make changes if necessary. The hypothalamus is a part of a organisms brain that controls its body’s homeostasis system. There is a theory called duel control theory that assumes that the feeling of hunger and satiation are controlled by two

There are many different genes that play a role in the understanding of cancer‚ and one of the most important of these genes is p53. P53 is a tumor suppressor gene‚ a gene that has the ability to prevent cancer but not allowing the cell to divide (Weinberg 2014). P53 is considered the “guardian of the genome” due to its variety of functions that are crucial for regular cell life cycles‚ and can prevent cancer (Weinberg 2014). Some of the functions of p53 include regulation of apoptosis‚ inducing

Introduction As a generalist social worker it is important and imperative to learn and use theoretical approaches when working with an individual or family. Theories are an interrelated set of concepts that have been organized to explain a problem and to remove barriers and challenges that have or are affecting a system. Utilizing a theory assist in removing the negative and focuses on the positive that will impact change in the individual or the family. However theories can be complicated and it

The purpose of this lab was to investigate how size of seeds impact respiration rate. It was hypothesized that bigger seed will require more oxygen because more energy is needed to sustain the seed’s homeostasis. For this experiment 4 groups was set up with 0.5 mL worth of the following seeds: peas (1) ‚ black beans (1)‚ radish seeds‚ and glass beads (control). The black bean served as the biggest size‚ peas were medium‚ and radish seeds were the smallest. After setting up the microrespirometer and

Provide a physiological explanation for changes in heart rate from rest to exercise‚ as well as during recovery. Incorporate fundamental concepts of homeostasis in your answer. The obvious physiological change that happens when you begin to exercise is the heart rate increases. The more energy and oxygen you use‚ the harder your heart works to pump the necessary nutrients and release the CO2. When you

The endocrine system is one of our body systems that plays an important role in living. It comprises of many glands exerting hormones in maintaining the body’s internal environment also known as homeostasis. The endocrine system plays an important role in homeostasis because it maintains growth and development‚ maturation‚ reproduction‚ human behavior‚ metabolism‚ sexual function and controls functions of the tissues. It is partnered with the nervous system since the hypothalamus along with the pineal

They are both elements that the body cannot manufacture itself so it must be supplied by food. Although salt is the most common dietary source for these essential elements‚ sodium also available from various foods that contain sodium naturally. Sodium is a mineral element that plays a critical role in body physiology. It controls the volume of fluid in the body and
