<span>The correct answer is D. Micromanipulation allows interaction with precision. This is done under a microscope. With micromanipulation, in-vitro fertilization has come true, and is helping thousands of parents to become parents.</span><span />
The cell technology that was possible by the micromanipulation tools is reproductive cloning. It is a form of artificial reproduction that uses the cloning technique.
It involves creating an animal that is genetically similar to a donor animal by the somatic cell nuclear transfer technique. In this cloning, the newly produced embryo is put back into the uterus where it can implant and develop further. There are two types of reproductive cloning by cleavage and cloning by the transfer of a cell nucleus into an enucleated ovum.
In anatomical terminology there are several words to indicate the position or part of the body that is being mentioned in a more specific and precise way, a group of these terms are called directional terms, they focus on the position of a specific part, one of the words in this group is "anterior" it basically means "in front of". The sternum is in front of the vertebral column.
the aleveoli are like small balloons, but not large ones. they exchange oxygen and carbon dioxide molecules (so they contain small amounts of air like a SMALL balloon, or in this situation a small pouch).
