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.

Answer:
The solution is (5, 3)
Step-by-step explanation:
To solve this system of linear equations, let's use elimination by addition and subtraction. This approach is particularly easy because one equation already has +y and the other -y, summing up to zero:
4x+y=23
3x-y=12
---------------
7x = 35
Then x must be 5.
Substituting 5 for x in the first equation, we get
4(5) + y = 23. Then 20 + y = 23, or y = 3.
The solution is (5, 3)
Answer:
There is no solution
Step-by-step explanation:
Let's solve your inequality step-by-step.
6−3b<10−3b−18
Step 1: Simplify both sides of the inequality.
−3b+6<−3b−8
Step 2: Add 3b to both sides.
−3b+6+3b<−3b−8+3b
6<−8
Step 3: Subtract 6 from both sides.
6−6<−8−6
0<−14
