The correct sequence of events is : C,D,B,A.
Iron rich magma in the earth's core heats up because of radiation and the pressure exerted by the other layers of the earth. This heat in the crust trigger convection currents in the mantle. The magma closest to the core will be hotter and therefore less dense than other layers. Being less dense the layer will rise towards the crust, eventually becoming cooler and sinking back down in a circular motion.
The continued circular motion creates electric currents which then generates the magnetic field.
ok so I've done this problem before trust me:
A. bundles of microtubules that separate to opposite poles of a cell - CENTRIOLES
B. prepares protein-packed vesicles for release outside of the cell - VESICLES
C. small storage sacs containing water, food, and waste - VACUOLES
D. rough and smooth organelle that produces protein, steroids, and lipids - ENDOPLASMIC RETICULUM
E. tiny sacs at the end of the ER which contain protein - GOLGI COMPLEX
F. chains of protein fibers that provide support and shape - CYTOSKELETON
G. powerful enzymes used to process cellular activity - LYSOSOMES & PEROXISOMES
H. whip-like structures on cells that are used for movement - FLAGELLA
I. produces and assembles proteins - RIBOSOMES
Answer:
The four main classes of organic compounds (carbohydrates, lipids, proteins, and nucleic acids) that are essential to the proper functioning of all living things are known as polymers or macromolecules. All of these compounds are built primarily of carbon, hydrogen, and oxygen but in different ratios.

Answer: 101 neutrons
An element's atomic number is the number of protons in its nucleus. X has 52 protons. The mass number is simply the number of protons AND neutrons in the nucleus. Since 52 is given, it's correct to assume that the remainder consists of neutrons. 153-52 will give you the number of neutrons.
Hope this helps! :)
