How does a paramecium control its temperature?

Paramecium control its temperature by Ectotherm.

Explanation:

Paramecium has to control variation in different temperatures. Hence it undergoes ectothermal reaction to keep its temperature in control. It has got a high acclimation capacity which enables them to survive in the extreme conditions.

It’s found that Paramecium is able to perform well in maximum and optimum temperatures.

Internal gas utilization favours the respiration process in the Paramecium. Oxygen is diffused through the surface of the body to the protoplasm. At the same time carbon dioxide is discharged out of the cell through the surface.  

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.

it enhances antibody production by t cells of the adaptive immune system.

hope i'm right
