The <u>lingual tonsils</u> are lymphoid nodules located in the tissue at the base of the tongue in the rear of the mouth.
- At the base of the tongue, reactive lymphoid tissue makes up the lingual tonsils.
- Clinical manifestations of lingual tonsil hypertrophy include globus, dysphagia, and difficulty intubating patients due to glottis exposure.
- The lymphoid tissue near the tongue's base makes up the lingual tonsil, a typical part of Waldeyer's ring.
- It has been documented that one of the unique causes of unforeseen difficulties with endotracheal intubation and mask ventilation is acute inflammation and hypertrophy.
- Lingual tonsillar hypertrophy is a peculiar voice alteration presentation.
- If improperly handled, this group of individuals has the potential to significantly deteriorate, obstructing their airways and even dying.

Homologous chromosomes pair up and exchange segments of DNA.
Option A
<h3><u>Explanation:</u></h3>
Crossing over is an event of Prophase 1 of meiosis 1. It occurs in the zygotene phase of prophase 1. Here the homologous chromosome pairs get very close together and gets packed within protein coat. The enzymes randomly cut the DNA segments from both chromosomes at same loci and exchange them with each other. This results in the exchange of genes between the two chromosomes. This is how the variation comes to place between offsprings of the same individuals. The crossing over results to form X shaped intersections between homologous pair of chromosomes which is called as chaismata. This phase occurs in pachytene phase and is visible in diplotene phase when the protein coat dissolves.
