Organisms change their behavior in responses to changes in the environment.
All living things can respond to stimuli in the exterior environment, it is a form of energy-light waves or sound vibrations, From what they sense they will make necessary changes to their diet and or where they are located. Such as winter weather which is a type stimuli will cause some animals to start talking.
An electron is found whizzing around the nucleus, so in subatomic particles.
There are 6 molecules of Mg3(PO4)2
6 × 3 = 18 Mg
6 × 4 × 2 = 48 O
Answer:
B
Explanation:
It is a gas and therefore according to particle model of matter it has large spaces between them and does not have a definite shape
Answer:
The correct answer is;
5. They were packaged at a higher pressure on the ground, thus causing the gas inside the packages to expand in the sky where the jet is at a lower pressure.
Explanation:
According to Boyle's law, the pressure of a given mass of gas is inversely proportional to it volume at constant temperature
P₁·V₁ = P₂·V₂
At the factories, the peanuts are packaged at atmospheric conditions whereby P₁ = 1 atm, however, the pressure of the air in the atmosphere decreases with altitude as such the pressure in the airplane jet is about a fraction of hat on the ground by about a factor of 0.7.
Therefore P₂ = 0.7 atm and we have
V₂ = P₁·V₁/P₂ = 1 atm×V₁/0.7 atm = 1.43·V₁
The volume increases at high altitudes
