Answer:
increasing extension time
Explanation:
The Polymerase Chain Reaction is a technique widely used in molecular biology laboratories to amplify target DNA regions. The standard steps of a PCR are as follow 1-denaturation, 2-annealing and 3-elongation/extension. These steps are repeated 15-40 times in order to exponentially amplify the linear DNA fragment. It is well known that longer extension times can be used as a strategy to increase the yield of longer PCR products. This is because the extension time depends on the synthesis rate of the DNA polymerase used in PCR technique and the length of the DNA fragment to be amplified.
Answer:
Explanation:
The pH scale stands for the power or potential of hydrogen. It measures how acidic or basic a solution based on the concentration of hydrogen ions and a scale from 1 to 14.
This scale is unique because it is logarithmic. So, every time the pH changes by 1 on the scale, the actual concentration of the solution increases or decreases by a tenfold.
So, a solution with a pH of 7 is ten times more acidic than a solution with a pH of 8. This can be translated to:
The black coffee has a pH of 5 and the hand soap has a pH of 10. We want to find how many times more acidic coffee is, so we subtract 5 from 10 and get 5. The difference in pH is 5.
Coffee is <u>10⁵ or 100,000 times more acidic than hand soap.</u>
Deductive reasoning.
Deductive reasoning is a type of reasoning where a general fact is broken down into a more specific case to make an inference. This general fact can be a broad branch of knowledge then gets into its parts that may comprise this broad knowledge.
Answer:
The dihybrid ratio we expect in the offspring is 9:7.
Explanation:
This is an example of complementary gene interaction, which is the non allelic interaction or genes, where the prominent genes at heterozygous loci may complement each other by complementing recessive alleles at the respective loci.
So in this case of complementary gene interaction, the individuals that are A-bb or aaB- or aabb will have the same set of observable features (phenotype) but only A-B- individuals will how the dominant phenotype.
<h2>Answer:</h2>
Trash is unsanitary and can attract pests it is important that trash is taken out to the dumpster otherwise it can cause serious infection in the individuals of a society.
Garbage pollution is the main reason for various bacterial diseases. Gastrointestinal, stomach pain, vomiting and diarrhea, cholera, typhoid, malaria skin diseases and respiratory allergies are the diseases which are caused by the garbage.
The smoke from the burning garbage not only poisons the air, it also increases the spread of diseases. Recent research has provided information about emission of toxic gases like carbon dioxide and carbon monoxide due to the burning of waste.
