The larger and heavier the box, the more force you must use when pushing.
The continental crust is the layer of granitic, sedimentary and metamorphic rocks which form the continents and the areas of shallow seabed close to their shores, known as continental shelves. It is less dense than the material of the Earth's mantle and thus "floats" on top of it.
Answer:
Silicon
Explanation:
The total of electrons: 2 + 2 + 6 + 2 + 2
In neutral state: #electrons = #protons = 14
so element with atomic number of 14 is silicon
Answer is #4 (neutrons)
Explanation:
Total mass before the reaction is 236 amu. The total mass of the two elements is 233 amu. This means that there are 3 amus carried by element X. Looking at the total atomic number of the two elements after reaction, it's 92, the same as the one at the beginning. This means that element X has zero atomic number, which could only be a neutron.
Amino acids are Proteins,
Lipids are Fatty acids
Nucleic acid which have nucleotides and, build RNA and DNA
Starches are a cause of Carbohydrates, after lots of Polymers.
So, therefore the answer is a)
