Hydras and jellyfish both live in a freshwater lake that is slowly being acidified by the runoff from a chemical plant built ups
Pavlova-9 [17]

Answer:

Jellyfish

Explanation:

  • The mode of reproduction that is used by hydra to produce offsprings is asexual whereas the jellyfish is capable of reproducing sexually.
  • When an organism reproduces asexually then the rate at which the offspring are produced is faster, however, there is a lack of genetic diversity as the offsprings are produced from a single parent.
  • However, in case of sexual reproduction there is more variation and hence in case of a changing environment such as acidification of a lake by a runoff, there is a better chance of jellyfish to survive as it reproduced by sexual reproduction and thus has the ability to give rise to an offspring which will carry the trait to be more resistant.

Unlike the abdominal viscera the thoracic viscera is separated into two compartments by an area called the mediastinum. What is
borishaifa [10]
The importance of this compartmental arrangement is the fact that the mediastinum region of the body houses essential organs. The region contains the thymus, pericardial cavity, trachea, esophagus and major blood vessels. The separation provides these body parts with a barrier of tissues. The mediastinum also separates one lung from the other. This is functionally important as it allows one lung to work independently of the other in cases where one may be diseased or injured.
