The second question (What type of cell..) the anwser is <u>C. Animal cell</u>
Explanation:
hope this helps :)
Answer:
Differentiated cells have retained all their genetic potential
Explanation:
Differentiated cells are important in a multicellular organism because they are able to perform a specialised function in the body. Multicellular organisms must therefore retain some unspecialised cells that can replenish cells when needed. These unspecialised cells are called stem cells.
The most likely explanation for the variation is the offspring were produced from different combination of genes. A single pair of gold fish mentioned in the question means a male and a female gold fish. The two of them mated and contributed different genes to the fertilized fish eggs, this results in production of various body shape and colouration which is known as variation.
