The correct answer is marsupials.
<span>Marsupials are any members of the mammalian class Marsupialia and are endemic to Australasia and the Americas. The main characteristic common to these species is that most of the young are carried in a pouch because they give birth to relatively undeveloped young. Examples of marsupials include kangaroos, wallabies, koalas, possums, opossums, wombats, and Tasmanian devils. </span>
Independent variable: Temperature

Boiling point 100C
Dependent variable: breaking point of rubber bands measured in certain amount of temperature
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>
