Hey there!
Here are some observations you can make to conclude this is a fish:
~Gills
~Fins
~Scales
These three things normally tend to only be on fish. However, reptiles may have some of these characteristics as well.
Hope this helps!

Answer:constriction of pupil
Explanation:the circularly arranged smooth muscle fibers in the highlighted structure ie the iris causes constriction of the pupil.
The iris basically has ciliary muscles that control Lens shape ,this happens when the ciliary muscles under the signal of the parasympathetic nervous system contract leading to the constriction of the pupil and when these muscles relax then dilation of the pupil will occur
Rhinoviruses are transmitted through the air or via contact. We might expect this sort of transmission to require a fairly healthy host (one who gets out and comes into contact with others) and, hence, to select against virulent strains. If we take precautions and try to stay away from people or avoid any contact with people, more hand-washing stations, increased attention to sanitization, and isolation of patients will help to reduce the transmission of the disease and, in the process, may favor the evolution of less virulent strains of the virus.
A. -50 degrees, it may also be 60 degrees but -50 is much more harsh
