T killer cell or Cytotoxic T cells are the cells in animals that are used to destroy bacteria and viruses after combining with lysosomes.
<u>Explanation</u>:
The T cells kills the bacteria and virus. The T cells can easily identify the pathogen when combined with the lysosomes. The activated T cells releases a material called perforin. This substance gets into the walls of the affected cell and punctures its walls. Due to hole in the walls, there happens discharge of fluid and electrolytes, which leads to the death of the cell. The substance secreted is the cytolytic proteins from the lysosome which helps in destruction of the infected cells.
Answer:
C) specialists.
Explanation:
The finches of the Galapagos Islands would be considered specialists. This is because the finches have diversified in a way in which each species has uniquely evolved to perform a very specific task (eating a particular type of food). Moreover, this process is known as adaptive radiation, as a single lineage (the original finch) undergoes speciation events that eventually fill divergent ecological niches, creating many related species.

<span>Hirschsprung's disease is a congenital anomaly also known as congenital aganglionosis or aganglionic megacolon. It occurs as the result of an absence of ganglion cells in the rectum and other areas of the affected intestine. Chronic constipation beginning in the first month of life and resulting in pellet-like or ribbon-like stools that are foul-smelling is a clinical manifestation of this disorder. Delayed passage or absence of meconium stool in the neonatal period is also a sign. Bowel obstruction especially in the neonatal period, abdominal pain and distention, and failure to thrive are also clinical manifestations.</span>
