Answer:
Cloning is the mechanism by which one living organism takes genetic material and produces identical copies of it. Cells, organs, chromosomes and whole species have been cloned by geneticists.
<u>The scientist need to take of some of the issues before cloning of sheep are as following:</u>
- Conflict with long-standing religious and social values about human dignity, probably infringing the principles of equality, identity and autonomy of each person.
- Cloned embryos face the same difficulties as naturally occurring pregnancies, plus others that are unique to cloning, so embryonic condition should be maintained.
- Cloned embryos surviving pregnancy may be born with a number of birth defects and other health issues.
- However, cloned cells can lack the programming required to tell the genes when to turn on and off. The outcome could be disorganised cell growth or abnormal functioning of the cell, all of which may lead to death of an organism.
Ecological models commonly have limited applications because the models included and the whole of them are from generalizations. And another reason is because ecological models focus on a population level and also an individual level which affects it applications and it caused for limited distributions.
Water goes downhill and the earth isn't Very spherical so it'll have ways for the water to go down and up to distribute the water around the world.
