Explanation:
Electroplating involves the coating of one metal on another metal. It is an electrochemical process. The positive electrode is the coating metal while the negative electrode is the metal on which the coating is to be performed.
Since copper is to be coated on an iron nail. A copper plate is made the positive electrode while the iron nail should be the negative electrode.
The electrolyte used in the process should be a copper salt e.g CuSO4 solution.
As electrolysis progresses, the copper electrode(positive electrode or anode) gradually wears away due to the fact that the copper ions are going into the solution and are being deposited on the iron nail.
Answer:
Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor. hope this helps
Explanation:
A
Before meiosis begins, during S phase of the cell cycle, the DNA of each chromosome is replicated so that it consists of two identical sister chromatids, which remain held together through sister chromatid cohesion. This S-phase can be referred to as "premeiotic S-phase" or "meiotic S-phase".
<span>Lysosomes are organelles which are responsible for breaking down and digesting wastes in the cell.
Lysosomes and vacuoles have the same functions. Both are enclosed organelle compartments within a cell and are recycling centers responsible for breaking down substances or complex molecules that goes into a cell. Both are sacs which contain digestive enzymes for breaking down foreign materials, food, and pathogens. Vacuoles are found in plant cells and lysosomes are in animal cells. Vacuoles play an important role in plant’s food production. It stores water and hydration of plants.<span>
