do the classification keys you have just worked with have any limitations in distinguishing between species? please answer in dying here guys

I dont really know what your trying to interpret? but I just hope this helps ya bro.

I think no because It is only useful when the organism that is being identified was or is a part of organisms that are part of the key.

please feel free to correct me if im wrong. ︎

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.

lysosome is this part of the cell is surrounded by a very thick outer membrane to protect the rest of the cell from its strong enzymes.
