Answer:
In order to propose a hypothesis, there is a need to first see the function of gills in fishes. The gills of fishes comprise blood vessels that exhibit inherited tendencies of getting oxygen out of the water, which was consumed by fishes from their mouths. These gills also comprise thin walls, and when water moves over these walls of blood vessels, the oxygen from water moves into the blood, and then this oxygen-enriched blood goes to various organs.
Thus, one of the hypotheses in the given case, can be the number of blood vessels, which are found in the gills of the mentioned freshwater fish to be higher in comparison to the blood vessels found in the normal fishes, and apart from this, the surface area of the thin walls, which are found in the gills is also more in the new species of freshwater fish.
Answer:
When CO2 is breathed into the lungs, it dissolves in the water there, diffuses across the alveolar-capillary membrane, and enters the bloodstream. As it combines with water, it forms carbonic acid, making the blood acidic. So CO2 in the bloodstream lowers the blood pH.

Complete question
Which term describes the perception of the body's movement through space?
A. nociception
B. neurasthenia
C. kinesthesia
D. dimensionality
Solution
The word Kinesthesia is made up of two words kinetic and anesthesia. On one side kinetic means movement while anesthesia means feeling, sensation, visions etc.
Whenever a person senses his/her body movement through space or any other kind of physical bodily movement or action, he/she actually faces Kinesthesia. This is also related with the Charles bell concept of sixth sense through which one could perceive sensation of static position or velocity of the movement
Hence, option C is correct
