Answer:
c
Explanation:
Random distribution of the Isopods should be 50/50 in A and B.
Chi-square = 
where O = observed frequency and E = expected frequency
Chamber O E Chi-square
A 18 10 
= 6.4
B 2 10 
= 6.4
<em>Total Chi-square </em>= 6.4 + 6.4 = 12.8
<em>Degree of freedom</em> = 2 - 1 = 1
<em>Tabulated Chi-square</em> (α = 0.05) = 3.8415
The calculated Chi-square exceeds the critical value, hence, it is significant and not due to random.
<em>The correct option is </em><em>c</em><em>.</em>

Answer:
They have a closed circulatory system.
Explanation:
In an open circulatory system, blood vessels transport all fluids into a cavity. When the animal moves, the blood inside the cavity moves freely around the body in all directions.
Closed circulatory systems are different to open circulatory systems because blood never leaves the blood vessels. Instead, it is transferred from one blood vessel to another continuously without entering a cavity.
