Homeostasis is the state of maintaining steady internal conditions by the living organisms. Cells obtain energy through the process of cellular respiration. It is a metabolic process of conversion of the biochemical energy from the nutrients into adenosine triphosphate (ATP). It also maintains the temperature of the body. The energy produced during this process is used in the cell division and repair of the cells by the breakdown of ATP and maintains homeostasis. They exchange substances with the new cells and also eliminate the wastes thereby maintaining homeostasis.

Answer:
0.0334N
Explanation:
Given parameters:
M1 = 5 x 10⁶kg
M2 = 1 x 10⁶kg
Distance = 100m
Unknown:
Gravitational force = ?
Solution:
To solve this problem, we use the Newton's law of universal gravitation.
Fg = 
G is the universal gravitation constant
m is the mass
r is the distance
Fg = 
= 0.0334N
We can see it as two movements: one on the north-south axis and one on the west-east axis.
On the north-south Axis, the hiker went 8 km north and 4 km south, so in total the hiker went 4 km north (we can subtract one for the other and the direction remains that which was bigger)
On the west-easth Axis, the hiker went 6 km east and 6 km west, so in total the hiker didn't move on this axis! or, he/she moved but then "came back"
So in total, the hiker only moved4 km north - answer B.

Here molecules of gas remains constant. If more pressure is applied to the piston, gaseous molecules will come closer to each other. Hence their volume decreases and density increases. Hope this helps you.
