We determine the mass of the metal in grams by weighing it using the balance.
Next we obtain the volume of the metal by measuring its displacement with a graduated cylinder and water in the following way:
1.measure amount of water in the graduated cylinder.
2. Place metal into the graduated cylinder
3. Measure the amount of water in the graduated cylinder
4. Subtract step 1 from step 3. The difference is the metal's volume.
Once we have found out the mass and the volume then we calculate the density using the formula:
Density = Mass/Volume.
We then check our answer from the known densities of metals in the table of densities that has been provided and determine the identity and purity of the metal by how close our answer is to the most probable value in the table.

Explanation:
In DNA, there are four possible nitrogen bases – adenine (A), guanine (G), cytosine (C), and thymine (T). In DNA, nucleotides combine to form two long chains that intertwine with each other, like a ladder that has twisted into a spiral.
Answer:
yes
Explanation:
thornless roses are often a result of a natural mutation that results in a chimera
Answer:
Option D, leaves
Explanation:
The maximum concentration of zinc is accumulated both in the leaves and stem of corn and tobacco plants. But comparatively it is higher in the leaves than in the stem.
Zinc is a micro nutrient as it is required only in a small amount and it is found that plants will lesser zinc concentration dry out easily.
Also the relation between the zinc absorbed is linear to the accumulation of zinc in the leaves. Hence, the higher the zinc absorbed in the corn and tobacco plants, the higher is the zinc accumulating in the leaves.
Hence, option D is correct
