Part A
zhuklara [117]

Answer:

The fossil of the dinosaur looked like it was a combination of two different types of extinct organisms: the meat-eating Tyrannosaurus rex and the Brontosaurus, which was an herbivore. Frankenstein was the name of a monster in a popular story about a scientist who built a monster in a lab. However, this species of dinosaurs evolved naturally. So, calling this species “Frankenstein” wouldn’t be completely accurate.

When studying animal behavior, the distribution of organisms within a choice chamber can be studied to identify animal preferenc
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>
