Answer from: HyperZ

Electrophoresis separates polypeptide chains and DNA chains by their fragment sizes after they have been cut by restriction enzymes are specific sites. Genetic testing involves checking genetic disorders by evaluating DNA sequences or protein amino acid sequences. By using restriction enzymes to cut DNA or polypeptides at specific sites, then run them on an electrophoresis, bands will form that will help indicate whether one has an abnormal sequence at the target site. If so, further analysis is used to determine the sequence by use of next-generation sequencing machines

During genetic testing, a segement of amplified DNA obtained from gene is digested using a restriction enzyme. Electrophoresis allows one to analyze the patterns by separating DNA by size. The process allows separation of different sizes of DNA fragments and provides genetic information in a wide range of data fields. A good example is genetic testing; Human DNA can be analyzed to provide evidence in criminal cases, to diagnose genetic diseases, and to solve partenity cases.

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat. although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.

What is the difference between cytokinesis in plant and animal cells? animal cells dived by a cleavage furrow. plant cells divide by a cell plate that eventually becomes the cell wall. cytoplasm and cell membranes are necessary for cytokinesis in both plant and animals.
