A liquid is some type of gas and we use liquid every day
Answer: Convection Currents
Explanation:
Due to the different temperature occurring at the upper and lower layers of the mantle, it causes heat transfer to occur. One of such heat transfer is the Convection currents which causes warmer, less dense rock material in the core to rise through the mantle. Also, the cooler rocks in the higher mantle move slowly towards the core.The movement caused by these Convection current in the Earth are called plate tectonics which are responsible for earthquakes and volcanoes.
n propene molecules == polymer (polypropene)
We have to know what fraction of the carbon dioxide exhaled by animals is generated only by the reactions involved in oxidation of pyruvate to acetyl coa.
The fraction is: 1 CO₂ per puruvate molecule.
Pyruvate oxidation takes place in the mitochondrial matrix, before chemical reactions begins, pyruvate enters the mitochondrion crossing the inner membrane and arriving at the matrix.
Oxidation of pyruvate results acetyl coenzyme A after release of one molecule of CO₂.
Answer:
C. It decreases by a factor of 4
Explanation:
F1 = kq1*q2/r²
F2 = kq1*q2/(2r)² = kq1*q2/(4r²) = kq1*q2/(r²*4) = F1/4
