1. A. Homeostasis is defined as a condition of equilibrium in the body internal environment. For example the internal organs‚ behaviors‚ body temperatures. In homeostasis it can be considered as dynamic as it is always changing. The liver‚ kidneys‚ autonomic nervous system and endocrine system‚ and hypothalamus help maintain homeostasis. For example‚ my brother has imbalance homeostasis due to having seizures. Because his brain is not functioning correctly‚ his homeostasis is not balance. B. Medial

Abby Goldschmidt Honors Biology 2° Mrs. Gempel September 3‚ 2015 Daphnia Lab Results Paper Abstract The goal of the study was to observe the effects of multiple chemicals on a Daphnia magna’s heart-rate compared to a control (pond water). The different chemicals were caffeine and alcohol. The heart-rate was the main variable in this experiment. The Daphnia’s heart-rate was observed for 15 seconds and then multiplied by 4 to show its heart-rate in one minute. This was repeated 4 times for each

network of vessels and organs that is in charge of the hormones‚ flow of blood‚ nutrients‚ and oxygen and other gases to and from the cells. Without the circulatory system‚ the body could not function properly. The circulatory system maintains homeostasis in a number of ways. In times of need the blood vessels come together to direct the blood to wherever it is required in the body. Also‚ the circulatory system gets rid of all waste products away from areas where they could build up enough to be

How does she fell about the change? How do your feeling differ from the narrator’s? The narrator is more passive as she first interacted with the yellow wallpaper in the big‚ airy room. Then the narrator becomes more active as she obsesses with the yellow wallpaper and the sub-pattern behind it and investigates

Stress has been a focus of study in medical science where it has been defined as a perturbation of the body’s homeostasis. This demand on mind-body occurs when it tries to cope with incessant changes in life. In the organizational context‚ stress has been found to be experienced by employees during job insecurity‚ performance expectations‚ technology changes‚ and personal

nervous system plays an important role in the normal functioning of the human organism‚ because it plays an important role of survival; it makes possible the kind of learning humans need to cope with changes in their environment. 4. It maintains homeostasis by controlling and regulating the other parts of the body. Like the functioning of muscles‚ movement‚ and brain functioning as well. 5. The nervous system is made of primarily two different kinds of cells in

First aid for cuts Cuts and grazes are part of growing up. Small wounds are usually easily treated at home with a little first aid and lots of TLC. The aim of first aid is to promote healing and to minimise the risk of infection. Large or severely bleeding wounds need immediate medical attention as blood loss can lead to falling blood pressure and shock. Home treatment Minor wounds * Wash your hands before handling a wound or wear sterile disposable gloves. * Most minor wounds stop
