The characteristics in the study included parameters such as the mating season, number of offspring, effect of environmental stress conditions and lack of mates. Out of all the parameters being studied can affect asexual reproduction in the mud snail but lack or presence of mates is a parameter required to be studied to determine the mode of reproduction i.e. sexual or asexual because need for mates or mate dependent reproduction occurs in case of sexual reproduction.

Gastro-esophageal reflux disease is a disease in which the upset stomach causes re-flux of acid back to esophagus. This may produce highly uncomfortable feeling of chest burn that may last even for two hours. GERD can get worse after eating because more volume of acids are released by stomach on detection of food like fast food and food that have high protein content.
