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:
As the bubble is a spherical entity, the probability of total internal reflection from the watery films is high due to its curvature. As a result, most of the light rays get reflected and therefore the air bubble shines brightly with some sparkling in water
Answer:
Chlorophyll is a cell that comes from plants not animals.
Explanation:
