Question Discussion & Solution

The correct answer is Liver.

Key Points

• The liver secretes bile juice, which is a digesting juice.
• Bile is stored in the gallbladder.
• Bilirubin and biliverdin, as well as bile salts and cholesterol, make up bile juice.
• Bile juice helps in the emulsification of fat.
• Large fat globules are broken down into smaller globules by bile juice, making it easier for pancreatic enzymes to act on them.
• The human liver is the largest gland in the body.
• The liver is situated on the right side of the stomach.
• The main function of the liver is to produce bile pigment.
• Ammonia and urea are produced in the liver.

Additional Information

• Insulin and Glucagon are the hormones secreted by the pancreas.
• The nutrients in digested food are absorbed from the small intestine.
• The stomach is a hollow organ that holds food while it is being mixed with stomach enzymes.

Concept:

WSDL stands for Web Service Description Language, is an XML based definition language. It’s used for describing the functionality of a SOAP based web service.

Additional Information

WSDL files are central to testing SOAP-based services. SoapUI uses WSDL files to generate test requests, assertions and mock services. WSDL files define various aspects of SOAP messages:  

• Whether any element or attribute is allowed to appear multiple times
• The required or optional elements and attributes
• A specific order of elements, if it is required

In alphabet group there is difference of five except ‘QU’

E + 5 → J

O + 5 → T

Q + 4 → U

 M + 5 → R

The correct answer is Solar cells.

Key Points

• A solar cell, or photovoltaic cell, is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect.
• Photovoltaic cells consist of two or more layers of semiconductors with one layer containing positive charge and the other negative charge lined adjacent to each other.
• Sunlight, consisting of small packets of energy termed as photons, strikes the cell, where it is either reflected, transmitted or absorbed.
• When the photons are absorbed by the negative layer of the photovoltaic cell, the energy of the photon gets transferred to an electron in an atom of the cell.
• With the increase in energy, the electron escapes the outer shell of the atom.
• The freed electron naturally migrates to the positive layer creating a potential difference between the positive and the negative layer.
• When the two layers are connected to an external circuit, the electron flows through the circuit, creating a current.
• Advantages of Photovoltaic Cells:
  • ​Environmental Sustainability
  • Economically Viable
  • Accessible
  • Renewable
• Disadvantages of Photovoltaic Cells:
  • ​The efficiency of solar panels is low compared to other renewable sources of energy.
  • Power generated gets reduced during cloudy weather.
  • Long-range transmission of solar energy is inefficient and difficult to carry.
  • Photovoltaic panels are fragile and can be damaged relatively easily.

In the question figure, there are 2 square blocks. Half of both square blocks are shaded and the other half is blank. One of the square blocks has its left half shaded and another square block has its right half shaded. Thus, in the answer figure, the square block whose left half is shaded should have its right block shaded and the square block whose right half is shaded should have its left half shaded.

Therefore option 1, 2, and 4 gets eliminated.

Hence, the figure in option 3 is the correct answer.
