Answer:
B. a decrease in the number of pathogens in the body
Explanation:
White blood cell includes immune cell like monocytes, macrophages, neutrophils, basophils, eosinophils, etc. These cells are responsible for fighting with the pathogens or foreign molecules and eliminate them from the body.
So when any pathogens get enter in the body these cell kills those pathogen and protect us from them. Therefore the decrease in the number of pathogens in the body is a direct indication that the white blood cells in the body are working. So the right answer is B.
The cells that are responsible for the resorption of bone tissue that carves out the spongy bone's trabeculae is the osteoclasts.
<h3>Bone remodelling</h3>
The remodelling of the bone involves the shaping and reshaping of the bone by the independent actions of the osteoblast and osteoclasts.
The osteoclast are cells that originates from the myeloid linage that are involved in the clearing away of mineralized and calcified constituents of the bone matrix which are damaged.
The clearing away of the damaged part of the bone is called the remodeling of the bone.
