Answer:
12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro's Number (6.0221421 x 1023).
Explanation:
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.
Multi cellular colonies of plant cells adhere to each other primarily by cell walls, whereas multi cellular colonies of animal cells are typically held together by proteins
<h3><u>
Explanation:</u></h3>
The organisms that contains more than single single are called as multi cellular organisms. They are just opposite to the uni cellular organisms. When many identical organisms groups to form together it is called as colonies.
It will be difficult in removing any organisms that forms colonies with the multi cellular organisms.The multi cellular organism of the cells in the plants are bonded to each other with the help of the cells walls. In animal cells these are bounded together with the help of the proteins.
