Liono4ka [1.6K]
Since the liver is the primary organ for metabolism, then in the setting of liver injury there will be reduced metabolism of compounds such as hormones. If these hormones are not metabolized and degraded in the liver, then these hormone levels will increase.

<em>A particular example is that the hormone estrogen is increased in the setting of liver damage, causing males with liver failure to have feminine characteristics.</em>

Komok [63]

Answer:

c

Explanation:

Random distribution of the Isopods should be 50/50 in A and B.

Chi-square = \frac{(O - E)^2}{E} where O = observed frequency and E = expected frequency

Chamber         O                    E             Chi-square

  A                   18                   10             \frac{(18 - 10)^2}{10} = 6.4

  B                    2                    10             \frac{(2 - 10)^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>
