It has 2 significant figures
Answer:
is a manipulated variable the same as a independent variable?
False
Explanation:
Manipulated variable is not the same as an independent variable because independent variable just as the name imply varies while manipulated variable could either be dependent or an independent variable
The ice sheets are the large masses of the glacial ice, which are spread more than 50,000 square kilometres. Ice sheath have maximum of the fresh waters, and they are also referred to as continental glaciers. The glacial ice less, which are less spread than ice sheets are known as ice caps. Many ice caps together form an ice field. These ice caps flows in all the directions outwards. only valley glaciers flow downwards in valley.
Hence, the correct answer is option (b). They flow in all the direction.

Answer:
1. Designing of the target vector.
2. Insertion of the target vector into the embryonic stem cell
3. Selection of the cells
4. Injecting selected cells into the new cells
5. Breeding of mouse with a normal mouse
Explanation:
The target vectors are made by inserting markers into them. The target vector is inserted into ES cells. The vector generally recombined with the target gene and knock-out that gene. Sometimes, recombination of vectors occurs at incorrect place.
The cells survive in the presence of markers only if the target gene is incorporated with target vector. The cells with the target vector are injected into a normal developing embryo of mouse.
The developed mouse will consist of heterozygous knockout cells and its own cells. The normal mouse is bred with this chimeric mouse. The offspring of these mouse are able to transfer knock-out gene to next generation.
