sequential drop in the partial pressure of oxygen from 1 step to the next in a series of steps by which oxygen is transported from the atmosphere to the mitochondria.
It depends on how the mixing is performed. If you take the two solids and mix them then it is a physical change as you get a heterogeneous mixture of solids. If you dissolve and them and mix the solutions- then a chemical change may occur- as different compounds are formed. Na2CO3 + CaCl2---> 2NaCl + CaCO3
Trees and vegetation have to be cleared first when establishing paddy fields. If the land is hilly, then the landscape is terraced (like a series of steps) as paddy fields have to be flooded with water. Each field is dug out and earth is used to build dykes around the edges. Rice paddy fields are a substantial contributor of methane, a powerful greenhouse gas, as organic matter decomposes anaerobicly under the water. So paddy fields do change the environment in several ways.
it is aperiodic table
true
Physical and chemical?! Right on!
a chemical change because that cirtain substance is rotting :)
It is chemical change... It is also physical change........Thats because the appearance also changed.Its a chemical change because when something is evaporated, these steps include chemicals.
1. Melting of the candle is a physical change. 2. Burning and thermal decomposition are chemical changes.
Glycolysis is the first stage in cellular respiration. Glycolysis takes place in the cytoplasm of a cell. The second stage, which is the Krebs cycle, takes place in the mitochondria of a cell.

A mechanism is a series of elementary steps whose sum is the overall reaction. An elementary step is a reaction that is meant to represent a single collision or vibration that leads to a chemical change. So basically, you break down the chemical equation into intermediate steps.
What is a series of carefully planned steps that test a hypothesis?
a flight of steps
Three Steps to Heaven - TV series - was created in 1953.
