Explanation:
Nuclear transplantation method is the method in which the nucleus from a donor cell is removed and inserted in the target cell in which also it's nucleus has been removed or enucleated. The nuclear transplantations has slowed
embryologists to interfere the development of an organism and to study nucleus to direct development. It has been used for the cloning of several species.
Nuclear transplantation has failed in cloning because variations in the completeness of epigenetic programming of the somatic cell nucleus.
Answer:
A. Oxygen atoms in water molecules are also attracted to hydrogen atoms in other water molecules.
Explanation:
Water molecules are forge by hydrogen bonds with one another. Here, the partly negative charge on the Oxygen (O) of one molecule would forge a hydrogen (H) bond with the partly positive charge on the hydrogens of its neighbouring or other molecules. Water molecules can also form a bond with other polar molecules and ions.
In the diagram, H is white and O is gray coloured molecules.
