how do you identify a pure metal if you have a balance of a graduated cylinder and a table of densities for metals?

1 answer:

4 0

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.

All animals with eyes or the eyespots that have been studied so far share a gene in common. When the gene causes lack of eyes in

RSB [31]

Answer:

The correct answer is option C.

Explanation:

PAX5 refers to the member of the Pax gene family, which is, accountable for conducting the genetic information, which will encode the Pax-6 protein. It functions as a master control gene for the maturation of eyes and other sensory organs. Pax6 functions as a regulator in the formation of patterns and coordination needed for the proliferation and differentiation to take place effectively. This ensures that the procedures of oculogenesis and neurogenesis are taking place efficiently.

The PAX6 gene was the outcome of evolution in earlier animals comprising eyespots or eyes. The similar PAX6 gene generates distinct kinds of eyes in distinct species because of the difference in its control of PAX6 expression. At the time of the evolution of vertebrates, the biological clock opsin’s rh gene was chosen as a gene for visual receptor pigments.
