Answer
1. The writing utensil’s placement facilitates the drawing of two or more lines with a single stroke of the pantograph. This means while drawing an image two or more copies of varying sizes may be created at the same time. The pantograph mirror is used to extend or retract an image.
2. The operation of a pantograph relates to dilations and similarity in that both of the processes are done on the graph and it is possible to use similar triangles through measuring the size of the triangles. Pantograph contains links that maybe arranged in other ways because they contain a parallelogram.
3. You can use similar triangles to describe the working of the pantograph because the ratio of similitude is set when determining where to put the pin. When one triangle is moved with the part being specific to the point (tracing style), along the outline of the image, an enlarged/reduced version of the image is created by movement of the other triangle (drawing stylus point).
4. Pantograph has been replaced by modern ways of producing duplicates such as photocopying, mass printing and digital filing. This is because the technique is currently outdated and the fact that it is difficult to use then now due to their complex designs which does not allow users to properly grip an actual writing utensil like the pen.
Answer:
Genetic mapping for unequivocal identification of the potentially causative mutation
Explanation:
Galactosemia is a genetic disorder caused by mutations in the Galactose-1-phosphate uridylyltransferase (GALT) gene, which encodes an enzyme involved in the metabolism of galactose. Gene mapping is a technique widely used in genetics to identify the position of one locus a chromosome by using molecular markers to estimate genetic distances. Genetic mapping provides useful evidence in order to identify when a disease that is transmitted from parent to offspring can be associated with one or more genes and then determine which gene/s is/are responsible for this condition.
Answer:
Eukariotic cells are bigger and complex than bacteria. The difference between cystoskeleton of eukariotic and bacteria cells is the type of proetein in each one.
Explanation:
The cytoskeleton is composed mainly in arrays of protein filaments. Its function is to maintain the shape of the cell, maintain in place the organelles (such as mitochondria, nucleus, etc.) and the transport throughout the cell. Every cell has a cytoskeleton, eukaryotic, bacteria and archaea. Eukaryotic cells are bigger than bacteria and have more organelles in them to maintain in place, this is why cytoskeleton are bigger and complex. The bacteria are a single cell, simpler, with a few organelles, the cytoskeleton is more simple but important. The cytoskeleton is similar in both, the difference is the type of proteins in them. In bacteria are simple proteins, meanwhile, in eukaryotic are a complex protein.
