<span>The three daily activities that affect homeostasis include;
Temperature, glucose levels, ability lymphatic system.
Homeostasis is the tendency of organisms to auto-regulate and also maintain an internal environment within a stable state. The stable condition is when the optimal functioning of organisms and dependant on many variables.
For example, fluid balance and body temperature to be kept within certain preset limits. PH of extracellular fluid, potassium, calcium ions and concentration of sodium and blood sugar levels are also variables.
It is needed to be regulated despite the diet, environment, level of activities. They are controlled by homeostatic mechanisms which when comes together maintains life.</span>
Hmm, we use carbohydrates as our main fuel energy source but we also store energy in lipids.
Molten material is allowed to solidify into the final shape.
Casting defects occur during solidification:
Gas porosity
Shrinkage
Two stages of solidification:
