<span>Rocks are technically born from when tectonic plates collide during seismic activity which causes it to create a mountain. External forces such as wind, water, erosion, human interaction, are what cause pieces of this mountain to fall off and create rocks. This is also how they are transformed to create something as beautiful as the grand canyon all the way to perfectly smooth rocks.</span>
The true statement about the Krebs cycle is letter C.
acetyl-CoA combines with pyruvic avid to make glucose in the Krebs cycle. the
carbon atoms that enter the Krebs cycle as acetyl CoA, They combine with a

Answer: body systems that can directly impact fluid balance includes:
b)urinary system
c)respiratory system
f)sweat glands.
The correct option is B, C and F.
Explanation:
Homeostasis is the mechanism by which the body maintains a steady ( constant) internal physical and chemical conditions. The following variables needs to be kept in equilibrium for optimal functioning of the body system. They includes: the body temperature, fluid balance, blood sugar levels. These variables are in turn controlled by one or more regulatory systems which includes;
- urinary system:when blood volume gets too low or blood electrolytes get too concentrated, the kidneys can retain water thereby decreasing urine output. When blood volume or pressure is too high, the kidneys can excrete more water thereby increasing urine output.
- sweat glands: this regulates both fluid and temperature.
I hope this helps. Thanks
Tonicity is responsible for determining which direction water will diffuse across the plasma membrane of cells.
