Answer:
B. LZAQD
A. Younger than A but older than Q
Explanation:
To solve this problem, we simply apply the stratigraphic laws which are the law of superposition and principle of cross cutting.
- According to the law of superposition, in an undeformed sequence of strata, the oldest layer is always at the bottom and the youngest on top.
- In this case, we have a little disturbance but it did not affect much of the original bedding.
- So, the rock ages from L to Z to A to Q and D. L is the oldest and D is the youngest.
According to the principle of cross-cutting "features that cuts through a rock are younger than the layers they cut through". In this problem, the fault cuts through layers LZ and A which suggests that these layers are older than the faulting event. Layer Q is unaffected by the faulting so, the fault is older than the layer.
Answer:
7.53*10^23 atoms
Explanation:
Using stoichiometry convert moles of silver to moles of copper. Based on the equation, for every 2 moles of silver, 1 mole of copper is produced.
Then, convert moles to atoms with Avogadro's number.
Your answer should be 7.53*10^23 atoms.
To obtain pure magnesium chloride, the following separation technique steps are employed:
- add water and filter to dissolve magnesium chloride
- evaporate the water in the filtrate and then crystallize obtain pure magnesium chloride
<h3>What are separation techniques?</h3>
Separation techniques are the techniques employed in the separation of the constituents of a mixture.
To obtain pure magnesium chloride from a mixture of magnesium chloride, magnesium, calcium carbonate, and powdered charcoal, the following steps are employed:
- add water and filter to dissolve magnesium chloride
- evaporate the water in the filtrate and then crystallize obtain pure magnesium chloride
In conclusion, separation techniques are used to separate the constituent of mixtures.

I am answering this question with respect to organic molecules in proteins. In case of proteins, the sequence of proteins (order) greatly affects the function of protein.For example, in enzymes the binding site or catalytic site has a catalytic residues (organic molecules = amino acids) at specific positions. And these amino acids together catalyzes the reaction. Like Serine, Histidine and Aspartic in chymotripsin together catalyzes the hydrolysis of protein and they have specific order (i.e serine 195, histidine 57 and aspartic acid 102. So, order is very important in functionality of protein.
Secondly, the shape is very important. Like, in above example the -OH group of Asp protonates the carbonyl groups in substrate, the -OH group of Ser acts as a nucleophile and the -NH group of His acts as a base by abstracting the protons during the reaction. So, it is the shape of these amino acids which are helping in functioning the enzyme.
So, the correct answer is Order and Shape.
