<span>B. Bending of light decreases
</span>According to the law of reflection, it stated that when light strikes the boundary between different media, a portion of the light is reflected while another portion enters the medium. Thus, the process in which the ray of light crosses the boundary and enters the second medium is known as refraction. However, the velocity of light decreases when light enters a denser medium.

Sati [7]

Option (D) flagellated protist is correct.

The last common ancestor of all animals was probably a flagellated protist.

<h3>What is a Protist?</h3>
  • Any eukaryotic organism that is not an animal, plant, or fungus is referred to as a protist.
  • The absence of other eukaryotes means that protists do not constitute a natural group, or clade, even though it seems likely that they all descended from a common ancestor.
  • Protozoa is another name for protists that resemble animals. Some are parasites as well.
  • The four phyla that make up the Protozoa are flagellates, ciliates, spore-forming protists, and protists that resemble amoebas.
  • Nuclear membranes surround the DNA of protists.
  • Most protists are motile, or able to move, and many of them inhabit aquatic settings.
  • Protists can reproduce sexually and/or asexually, and their life cycles are intricate.
  • Protists consume, absorb, or produce food through photosynthesis.

Answer:

B. "Whispered pectoriloquy" - "speaking from the chest"; used as a means of finding masses in the lung. The whispered word is audible in areas where fluid or a mass is present

Explanation:

Auscultation in medicine, is the action of listening to sounds from the heart, lungs, or other organs, usually using a stethoscope, in order to perform medical diagnosis.

Auscultation is performed for the purposes of examining the circulatory and respiratory systems, as well as the alimentary canal. The procedure is best performed in a quiet examination room. A stethoscope is used to magnify internal sounds. Small changes in breath sounds are carefully observed in order to make a diagnosis.

Whispered pectoriloquy is used to detect vocal resonance. It is  used as a means of finding masses (consolidations e.g. pus) in the lung and is performed by having the patient quietly whisper a word. If fluid or a mass is present, words that are whispered may be heard clearly.
