The removal of excess wastes helps in maintaining chemical homeostasis and prevents breaking down of systems that causes a serious health issue.
<u>Explanation:</u>
Human body is composed of many different organ system that are inter related with each other's functions. If the function of one system is disturbed then the function of other system also gets affected resulting in affecting the entire human body functions. The system that is used to remove the excess wastes and unwanted things from the human body is an excretory system. It performs tow major function in a human body. It removes unwanted things and it also helps in draining the broken down components.
The excretory system helps in the control of internal chemical homeostasis. When a living organism's physical and chemical conditions are maintained steadily it is called as homeostasis. This system also helps in maintaining the human systems in a controlled and good condition thereby preventing the failure of other systems and serious health damages.
Answer:
69.152 % → 63Cu
30.848 % → 65Cu
Explanation:
As you know, the average atomic mass of an element is determined by taking the weighted average of the atomic masses of its naturally occurring isotopes.
Yo sup??
Heat produced per gram of reactant=13.1 KJ
.=13100 J
Actual heart produced=1850 J
By applying unitary method we get the weight of reactant to be x
x=1850/13100
=0.141 gm
Hope this helps
