The gastrovascular cavity is usually surrounded by tentacles that serves to trap their preys. Examples of cnidarians include corals, hydras and jellyfishes.
Answer:
<h2>
B) demonstrated that the nuclei from all the differentiated mammalian cells can retain their full genetic potential.
</h2>
Explanation:
Every cell of an organism contain equal number of chromosomes, like nerve cell, mammary gland cell, muscle cell, heart cell etc. all have same number of chromosome and equal amount of DNA. The morphology and functioning of different cell depends on the differential gene expression.
Cell express their genes according to the requirement or the environment or according to the signals.
The cloning of Dolly demonstrated that the nuclei from all the various differentiated mammalian cells can retain their full genetic potential.
Met Pro Val is the answer
