</span>Acceleration = Velocity / Time
Greater velocity / Lesser time
Greater Velocity = greater acceleration
Proportionality or variation is state of relationship or correlation between two variables It has two types: direct variation or proportion which
states both variables are positively correlation. It is when both the
variables increase or decrease together. On the contrary, indirect variation or proportion indicates
negative relationship or correlation. Elaborately, the opposite of what
happens to direct variation. One increases with the other variables,
you got it, decreases. This correlations are important to consider
because you can determine and identify how two variables relates with
one another. Notice x = y (direct), y=1/x (indirect)</span>
The
human body does not constantly lose water through hydration and circulation.
When someone is hydrated, he is drinking an enough amount of water to sustain
the needs of his body. Circulation then helps this in distributing the water in
different parts of the body.
<span>Metamorphic rocks form by existing rocks join together under high heat and pressure. Examples of metamorphic rocks are marble, schist, slate, and quartzite. Metamorphic rocks formed when the minerals are chemically changed due to heat and pressure. They are often seen near magma but they do not melt like igneous rock.</span>
The correct answer is the homeostasis.
A plant may close and open its stomata to prevent excess water loss and maintain homeostasis.
Homeostasis is termed as the tendency of organisms to maintain and automatic regulation of their internal environment to be in a stable condition.
We say that the plant is in stable condition when the fluid balance and body temperature are being kept in to a pre-set limits which include calcium ions, potassium, sodium and PH of extracellular fluid.
The natural resistance which changes the optimal condition brings about homeostasis.
