The process in which organ systems work to maintain a stable internal environment is called homeostasis. Keeping a stable internal environment requires constant adjustments. Here are just three of the many ways that human organ systems help the body maintain homeostasis:
Respiratory system: A high concentration of carbon dioxide in the blood triggers faster breathing. The lungs exhale more frequently, which removes carbon dioxide from the body more quickly.
Excretory system: A low level of water in the blood triggers retention of water by the kidneys. The kidneys produce more concentrated urine, so less water is lost from the body.
Endocrine system: A high concentration of sugar in the blood triggers secretion of insulin by an endocrine gland called the pancreas. Insulin is a hormone that helps cells absorb sugar from the blood.

Answer:
5.8 kg
Explanation:
We are given that
Force,F=40 N
Acceleration,a=
We have to find the mass of block.
Where
Answer:
6
Explanation:
The rate of change in this scenario corresponds to the number of inches that Ree grows every year. Basically, Ree's height can be written as a linear equation as follows:
where
x is the number of years after the first birthday
y is the height in inches
q = 27 is the height of Ree on her first birthday
m = 6 is the inches gained by Ree at each birthday
So the equation can also be rewritten as
y = 6x + 27
Answer:
R/2
Explanation:
Resistance of full lenght wire = R
Since length is divided into half but even then the resistance of each individual half is same i-e R
If connecetd into parallel mode then we know resultant resistance say 'r' is
1/r=1/R+1/R
or
1/r = 2/R
r= R/2
