Q:

In which article is intellectual property rights outlined?

A) Article 15 B) Article 27
C) Article 13 D) Article 20
 
Answer & Explanation Answer: B) Article 27

Explanation: Article 27 deals with Human rights. It is the Universal Declaration of Human rights. Hence intellectual property rights also fall under this segment. This says that patents will be available for any sort of invention, product, processes, etc.

Q:

Which of the following is a characteristic of piezoelectric biosensors?

A) Detects the change in light adsorption B) Detects the photon out for luminescent
C) Detects the movement of electrons between electrodes D) Detects the angle at which electrons are emitted
 
Answer & Explanation Answer: D) Detects the angle at which electrons are emitted

Explanation: Piezo-electric devices uses gold to detect the specific angles of the emitted electron waves. When the substance is emitted to the laser light it will emit electron waves. These waves vibrate under the influence of an electric field.

Q:

Which of the following is a characteristic of electrochemical biosensors?

A) Detects the change in light adsorption B) Detects the photon out for luminescent
C) Detects the movement of electrons between electrodes D) Detects the angle at which electrons are emitted
 
Answer & Explanation Answer: C) Detects the movement of electrons between electrodes

Explanation: For a given applied current, electrochemical biosensors study the movement of the electrons in redox reactions detected when a potential is applied between two electrodes. Thus, these biosensors can detect the change of the electron flow due to any reaction,

Q:

Which of the following is a characteristic of photometric biosensors?

A) Detects the change in light adsorption B) Detects the photon out for luminescent
C) Detects the movement of electrons between electrodes D) Detects the angle at which electrons are emitted
 
Answer & Explanation Answer: B) Detects the photon out for luminescent

Explanation: Photon output for a luminescent or fluorescent process can be detected with photomultiplier tubes or photodiode systems. The light produced can be detected photometrically by use if high voltage photomultiplier tubes.

Q:

Which of the following is a characteristic of calorimetric biosensors?

A) Detects the change in light adsorption B) Detects the photon out for luminescent
C) Detects the movement of electrons between electrodes D) Detects the angle at which electrons are emitted
 
Answer & Explanation Answer: A) Detects the change in light adsorption

Explanation: Calorimetric biosensors measure the changes in the colour. It measures the changes in light absorption. Many enzymes catalysed reactions are exothermic. The change in temperature can also be detected by the transducer.

Q:

In a pregnancy kit, which molecule does the kit actually test for?

A) Baby’s urine test B) Blood test
C) HCG test D) Amniotic fluid test
 
Answer & Explanation Answer: C) HCG test

Explanation: HCG or human chorionic gonadotropin is a hormone which is released during pregnancy. It is the only hormone which is detectable only in pregnant women. Even the presence of a very minute amount of HCG will give a positive result for the pregnancy.
