Answer:
Open circulatory systems are advantageous to some animals because they use less metabolic energy.
Explanation:
Open circulatory systems are also known as lagoon circulatory systems. In this systems the blood is not necessarily always inside the blood vessels; It leaves the heart and will directly irrigate the organs and then return by other means or mechanisms.
So that it can be understood more easily, it is necessary to think about this system acting in organisms much smaller and less complex than mammals or any other vertebrate of greater size. As this animals doesn't have a great size, they need to use less metabolic energy than more developed organisms, so this system allows them to save metabolic energy to be used in other living functions.
<span>Clouded Leopard are less abundant range wide than when last accessed in 2007. Some range countries have maintained status quo Clouded Leopard abundance, however, the majority of range countries have experienced moderate declines, with serious declines noted for Myanmar, Viet Nam and China. The causes of Clouded Leopard declines are attributed primarily to (1) direct exploitation, (2) range fragmentation, and (3) reduction in habitat quality. Clouded Leopard exploitation for pelts is well documented in several countries, including the infamous Tachilek market along the Thai–Myanmar border. The frequency of Clouded Leopard parts available at market indicates increased pressure from hunting (Oswell 2010). Ongoing deforestation in countries such as Myanmar and Cambodia is also leading to increased fragmentation and reduction of optimal habitat for Clouded Leopard.</span>

Explanation:
Archaebacteria are obligate anaerobes, i.e., they flourish in the strict absence of oxygen., and that is why only they can undergo methanogenesis.
The cell membranes of the Archaebacteria are composed of lipids.
The rigid cell wall provides shape and support to the Archaebacteria.
