Answer:
There are different types of reflexes, and some of them can be controlled voluntarily due to cortical processing.
Explanation:
Even if there is an initial myotactic reflex of moving away from the heat, the cortical processing that is subject to learning makes you not let go of the pan. It should be noted that there are different types of reflexes, and not all postural reactions are automatic. The cerebral cortex influences voluntary postural adjustment movements. Such control is mainly performed by the brain stem, where ocurrs the modulation of motor neurons and spinal cord interneurons through the lateral descending (fine movements) and medial (posture and balance) downward pathways.
Answer:
The correct answer is - tend to lose water by osmosis since their internal salt concentration is lower than that of seawater.
Explanation:
In freshwater fishes, the body of fishes has a higher salt concentration inside their body than the surrounding water, water enters through the osmosis process. Without any active regulation of this process, fishes would swell and get bigger and bigger. They have specialized cells called chloride cells in gills to take ions from water as they do not have kidneys.
In contrast, the marine fishes have a lower salt concentration in their body than surrounding water of sea or ocean and they lose water continuously and to compensate for this they need to drink water regularly.
