Science Assesment – Homeostasis Homeostasis is the state of body in the system which variables are regulated so that internal conditions remain stable and relatively construct. Homeostasis works by monitoring levels of variables and making connections by negative feedback mechanisms. Negative feedback is a reaction in which the system responds in such a way as to reverse the direction of change. The three components of a homeostatic control system is a receptor‚ this detects changes. The integrator

digestion‚ exercise‚ and fever. Some factors that may lead to a decrease in temperature include drug and substance abuse and metabolic activities especially those that are influenced by the thyroid gland. The hypothalamus plays an important role in osmoregulation. This is the part of the brain that is in charge of maintaining body temperature. It is designed to sense changes in the body temperature‚ either increase or decrease and respond accordingly. Whenever a temperature change is detected‚ the nerves

P4 – Explain the role of the kidney in the homeostatic control of fluid balance Homeostasis is how our body works to keep the internal environment constant. The kidneys play a role in the control of fluid balance. For this assignment I will be discussing the gross anatomy of the renal system and the kidney. Renal System The renal system is a group of organs that work together to produce‚ store‚ and release urine. It consists of 2 kidneys‚ ureters‚ the urinary bladder‚ urethra and renal vessels which

Diffusion and Osmosis lab Results: Figure 1a-rate of weight change in 15 min intervals of each concentration. The first tube showed very little weight change. However all other tubes show a greater change the concentration could be the factor that determines the permeability of the sucrose. The sucrose molecules are too large to pass through. Figure 1b- sucrose concentration determines the weight change. In this case based on our results as concentration increases the percent weight change

Classification The crayfish falls within the kingdom - anamalia‚ phylum - Arthropoda‚ Class - Crustacea‚ Order -Decapoda ‚ and family - Cambaridae. Habitat Crayfish like to be where it’s dark and cool‚ and during much of the daylight they will be found by them selves‚ under a rock or vegetation‚ waiting for dark‚ when they come out to forage for food. This is highly variable‚ ranging from deep holes to sluggish streams. A suitable habitat is medium-sized streams containing riffles and rocky pools
