The answer is natural killer cells.
Natural killer cells are a type of lymphocytes and they are important for the innate immune system. They recognise stressed cells much faster than other immune cells. Their response is rapid and usually only a few days after a viral infection. They also respond to <span>cancer cell </span>formation. While other immune cells can detect only those harmful cells that have specific markers on the surface of the cell membrane, natural killer cells can even detect those cells that miss markers for apoptosis.
Answer:
B. False
Explanation:
Orthologs are genes that find their origin in vertical descent,, paralogous on the other hand, are genes that are related via duplication events. <em>In the case of human hemoglobin, their genes originated by duplication from an common ancestral globin gen, therefore they are paralogous.</em>

The measurements indicated below that can involve a direction include Acceleration and Distance (Option A and C).
<h3>What do magnitude and direction mean?</h3>
Magnitude can be defined as a type of measurement based on a number or range value that does not involve orientation, while the direction is a magnitude that indicates orientation.
