When there is a cut in the skin and bacteria enter the body, the immune system responds. First, macrophages approach the area of
the cut. Next, the macrophages surround any bacterial cells and engulf them. What feature of the immune system is best described by this scenario? A. self-recognition, which is a part of adaptive immunity B. the phagocytotic barrier, which is a part of innate immunity C. antigen specificity, which is a part of adaptive immunity D. the inflammatory barrier, which is a part of innate immunity
The feature of the immune system which is best described by this scenario which involves engulfing of bacterial cells isthe phagocytotic barrier, which is a part of innate immunity and is denoted as option B.
<h3>What is Immune system?</h3>
This is part of the body which is responsible for protection and helps to fight germs and diseases through the white blood cells which are present in the body system.
The immune system comprises of macrophages which engulfs the pathogen through the process known as phagocytosis which is why phagocytotic barrier which is a part of innate immunity was chosen as the correct choice.
Kelp populations would be entirely depleted and it would impact the sea life that thrive off of kelp as their homes and source of food. Many sea creatures use kelp as a sort of barrier to prevent bigger fish from attacking them.
