I think the correct answer from the choices listed above is option D. Modern fishing practices threaten biodiversity mainly through the removal of community food supplies. When people remove a significant amount of fish, portions of the food web are disturbed and can affect a certain ecosystem.
The correct answer is option B. The scientists were studying if the mud snails can reproduce both sexually and asexually. 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.
