Dragonflies are most closely related to damselflies. Damselflies are smaller, slimmer, and most of them fold their wings along their body when they are resting.
The density uses this equation :
D = m ÷ v
D (Density)
M (Mass)
V (Volume)
⓵
Replace your numbers in the equation :
D = m ÷ v
D = 146 ÷ 32
D = 4,5625
D ⋍ 4,56
The answer to this is B.
Non-native species are very hard to handle because since none of the native species know what to do with it they mostly leave it alone which means that the non-native species will end up on winning the native specie and eventually end up killing the native plants and animals in the environment!
Hope this helped!!
