hope its correct :-)
Answer:
(a) The ones that are equivalent to the given fraction are:
and 
(b) The one that is equivalent to the given fraction is:
Look at the problem and do it in order
N=m-2
m-2n=8, using n from above in this equation yields:
m-2(m-2)=8 perform indicated multiplication
m-2m+4=8 combine like terms on left side
-m+4=8 subtract 4 from both sides
-m=4 divide both sides by -1
m=-4
So the correct answer is A) m=-4
Answer: Bladder
Step-by-step explanation:
The walls of the bladder contain very few blood vessels and are lined with guanine crystals, which make them impermeable to gases. By adjusting the gas pressurising organ using the gas gland or oval window the fish can obtain neutral buoyancy and ascend and descend to a large range of depths.
