12 years ago I was diagnosed with Meningitis‚ they caught it just in time. I hadn’t ever seen my mom that scared‚ I still haven’t. At the time my mom was going to be turning 20‚ we were still living with my grandparents and my 17 year old uncle. I was playing upstairs with my uncle when I suddenly passed out‚ all the color drained from my face‚ he picked me up and ran downstairs. I was driven to the emergency room. 30 minutes away. They told us what I had and that if we had waited even two more hours

Homeostatic Mechanisms Homeostatic mechanisms are essential for a body to maintain a stable condition. The word homeostasis describes the body’s ability to maintain its healthy state‚ while the world around it is changing constantly. There are many steps in the process of homeostasis. First‚ there is the stimulus that causes the change. Then the receptor detects the change. The information of the imbalance is then sent to the control center‚ which decides the response. The information entering into

Description The seals are named for and known for their thick fur. Europeans first named them sea bears. Seal pups are born with a black pelt and later on becomes a dark brown. The adult males have gray hair on the back of their necks. Males are much larger than females are. Size Male pups weight 5.4 kg at birth and then grow to 175-275 kg. Female pups weigh 4.5 kg at birth and grow to 30-50 kg. Population/Lifespan 1 Million but the population is decreasing due to people hunting the seals and

D2. Explain the importance of homeostasis in maintaining the healthy functioning of the body. Homeostasis is vital for the maintenance of healthy functioning of the body. It is important the body keeps to a narrow range of variables‚ and without it ‚ chemical reactions and metabolic processes within the body cannot be carried out properly‚ which can cause disease and complications. If the body cannot maintain its temperature‚ this can cause the person to overheat‚ resulting in hyperthermia. This

Feedback Mechanisms How do organisms regulate complex systems through chemical interactions? Why? The heating system of a house works to keep the temperature constant. If the house gets too cold‚ then the heat automatically turns on to warm the house. The heat stops when the preset temperature is reached. This is an example of a feedback mechanism. Organisms use many feedback mechanisms to either maintain or amplify important chemical systems. This could happen at a molecular level to coordinate

to repeat investigations to identify errors and correct them. Scientific theories can always be proven wrong. Seven shared characteristics of life are: cellular organization‚ homeostasis‚ metabolism‚ response to stimuli‚ reproduction‚ growth/development‚ and heredity. The basic unit of life is a cell. Homeostasis is the ability of a body to maintain stable internal conditions. Examples would include how we sweat and dogs pant. Response to stimuli is the reacting to outside forces. An example
