Which of the following is NOT a reason for the use of hybrid micellar liquid chromatography (HMLC)?
|
It requires extensive solvent use. |
|
The developed procedure is rapid, easy to handle, green since it uses a low amount of toxic chemicals providing reliable results. |

What was the primary methodological change in the HMLC technique used in the study?
|
Use of a micellar mobile phase with reduced solvent usage. |
|
HMLC is a modified version of the high-performance liquid chromatographic (HPLC) technique, where the composition of the mobile phase is a modified aqueous micellar mobile phase with a major part of water, surfactant (above critical micellar concentration) and low concentration of short-chain alcohols (i.e., 1-propanol, 1-butanol, 1-pentanol) as an organic modifier. |

According to the study, why might vegetable growers prefer other pesticides over Imidacloprid (ICP)?
|
ICP is less effective on pests. |
|
the required quantity of ICP was greater than OPs to kill the pest |

Considering the environmental impacts discussed, why is the HMLC method considered 'green'?
|
It involves less waste and uses low-toxicity solvents. |
|
Nevertheless, a hybrid micellar liquid chromatography (HMLC) can also be used. HMLC is a modified version of the high-performance liquid chromatographic (HPLC) technique, where the composition of the mobile phase is a modified aqueous micellar mobile phase with a major part of water, surfactant (above critical micellar concentration) and low concentration of short-chain alcohols (i.e., 1-propanol, 1-butanol, 1-pentanol) as an organic modifier. |

What is hyperthermia commonly used to treat?
|
Cancer |
|
Hyperthermia, the mild elevation of temperature to 40–45 °C, can induce cancer cell death and enhance the effects of radiotherapy and chemotherapy. |

Which method is used to apply heat directly to a tumor in local hyperthermia?
|
Hot water baths |
|
There are several methods for inducing local hyperthermia. One historical method is to expose tumours to external lights such as an infrared light or to submerge the tumour site in a water bath. |
