Answer:

The cloned sheep is the result of nuclear fusion from two different sheeps. In one sheep the enucleated egg is fused with DNA of another sheep.

Explanation:

The cloned sheep is the result of nuclear fusion of 2 different sheep. In the cloning process, the egg cell of one sheep was enucleated. Then a DNA from another sheep had taken and put into the enucleated egg cell to fuse. Then the egg allowed to divide in the laboratory to the blastocyst stage. The blastocyst incorporated into a surrogate mother or a third sheep. The surrogate mother after some months gives birth to the cloned sheep.

The sheep produced by normal reproduction has the DNA of two parents. The sheep have two parents and resemble their parents.

In cloned sheep, there is no biological parent and have DNA of the donor sheep. That means the cloned sheep has a gene of a single sheep not the DNA of others. Because the egg cell was enucleated before the cloning process. The sheep are more like the donor DNA sheep not like the surrogate mother.

Explanation:

This question is describing the excretory organs and their excretory products. Excretion is the process by which waste products of metabolism are removed from the body system.

- As mentioned in the question, the SKIN is an excretory organ that excretes SWEAT which is made up of water, salts, and chemicals like urea.

- Lungs is another organ that excretes carbon dioxide (CO2) and water (H2O) as products of cellular respiration.

- The large intestine also produces FEACES, which is stored in the last part of the large intestine called RECTUM before it is excreted through the anus.
