Of all the animals in the animal kingdom which one(s) would have the best chance for survival in mountains?
Fittoniya [83]

Answer & explanation:

Mountains are large formations of land at high altitudes, where conditions are often difficult. For example, cold weather and food shortages.

In the highest areas of the mountains, animals such as vultures, eagles, hawks and other birds of prey usually prevail.

In addition, it is common for the sides of the mountains to be covered with forests. In these areas it is possible to observe the predominance of animals such as moose, goats, sheep, skunks, llamas and lynx. This group has good climbing skills and manages to stay in the side of the mountains and in some high areas (not as high as the previous group).

Meanwhile, in the lower parts of the mountains, where the forest is denser, it is possible to observe the predominance of snakes, wolves, marmots, foxes, etc.

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>
