Reika [66]

Answer:

The correct answer is <em>A. real-time PCR can measure the amount of DNA amplified as the reaction proceeds, while standard PCR cannot.</em>

Explanation:

PCR (Polymerase Chain Reaction) is a molecular biology technique. Conventional PCR and real-time PCR are diferent types of PCR, and are both used to exponentially amplify DNA molecules. In both types, a polimerase enzyme is employed to sinthesize DNA copies. The main difference is that conventional PCR is qualitative whereas real-time PCR is quantitative. So, real-time PCR permits not only to detect and amplify DNA but also permits to perform a quantification of the target DNA. This is accomplished by measuring a fluorescence signal - which is directly the amount of DNA amplified- during the course of the reaction.

Pie

Answer:

1/1024 is the proportion of the F2 genotypes will be recessive for all five loci

Explanation:

When crossing between both parents, all genotypes will give us 100% AaBcCcDdEe. When a self-fertilization is performed this means that it can have a cross for example of two flowers of the same plant with the genotype AaBcCcDdEe In this way, given the law of independent segregation which states that the alleles of two or more different genes are distributed in the gametes independently of each other. The proportion that at this junction the alleles are aa (1/4)  bb (1/4) cc (1/4) dd (1/4) and ee (1/4). The proportions (1/4)* (1/4)*(1/4)*(1/4)*(1/4) are multiplied, obtaining a value of 1/1024

irina1246 [14]

Answer:

Based on this, you know that Sampson is using the whistle as a <u><em>secondary </em></u> reinforcer to train the dolphins.

Explanation:

Secondary Reinforcement can be described as a condition in which  a stimulus initiates a behavior after being previously associated with a primary reinforcer. A secondary reinforcement is a stimulus that satisfies basic survival instinct such as food, drinks, and clothing.

The same phenomenon was being used by Samson to train his dolphins to perform tasks. The dolphins enjoyed the sound of the whistle because previously that sound was paired to them getting their food.
