Answer: Low oxygen content.
Explanation:
There are many dangers to the survival of fish in shallow water that depend on the properties of water.
1. The oxygen content drops during the winter and also in hot weather. Fish cannot survive without enough oxygen in the water.
2. High evaporation rates can drain the pond.
3. Fortunately, water has a high thermal mass, so overheating the water to the boiling point is not an issue.
Of the three reasons given, lack of oxygen is the most critical.
the lithosphere is inbetween
Smooth muscle.
Blood vessels contain smooth muscle in their walls. Cardiac muscle is heart muscle specifically. Skeletal muscle is muscle that forms the voluntary muscles.
The rough endoplasmic reticulum also known as RER is covered in ribosomes and helps produce most of the proteins. Smooth endoplasmic reticulum also known as SER does not have these ribosomes, and it is almost solely for producing lipids.
Good luck :)
