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.
Answer:
Central canal
Explanation:
running through the osteon
central canal or haversian canal,contains blood vessels,nerves and lymphatic vessels.
Answer: Option A) the Golgi bodies and their vesicles.
The most likely explanation for the bad taste of meat that has "freezer burn" from repeated freezing is the destruction of the Golgi bodies and their vesicles.
Explanation:
Since the Golgi bodies serves as sacs for synthesis, packaging and distribution of materials in the cell, the long sharp crystals of ice will spear through the cell membrane, and then through the Golgi bodies and their vesicles.
This would cause them to spill their contents into the cytoplasm alongside the forceful withdrawal of fluids from the vesicles of Golgi bodies for freezing.
Thus, destruction of Golgi bodies and their vesicles most likely explain the bad taste of meat
