The right answer is climate change.
Amphibians do not have the possibility of producing heat. Their activity depends on the environmental temperature and its fluctuations. For example, an average temperature increase of 1 ° C is likely to increase the metabolic expenditure of ectotherms by at least 10 to 30%. Global warming has or will have a significant impact on populations and their ability to adapt according to the evolutionary history of species.
The correct answer is: smooth endoplasmic reticulum (smooth ER).
Smooth endoplasmic reticulum is a membrane organelle of the eukaryotic
cells which consists of tubular membrane vesicles. One of its main function is the synthesis of lipids and their storage. For example, cholesterol and phospholipids are stored in the smooth ER and then used for the synthesis of plasma membrane.
There is another type of ER- rough ER. The difference between these two ER on its outer surface have attached ribosomes- protein-synthesizing particles .
