The remote sensing technique known as _________ has enabled scientists to map more than 800 square miles (2,100 square kilometer

allsm [11]

From what we know, we can confirm that the remote sensing technique described in the question is that of laser scanning.

<h3>What is laser scanning?</h3>

This is, as described in the question, a remote sensing technique. This is a method most often used for land surveys, in which lasers are pointed at the area, which gather information in the form of 3D coordinates, which are later compiled to create detailed maps of the region.

Therefore, we can confirm that the remote sensing technique used by the PACUNAM project in order to map more than 800 square miles of the Maya Biosphere Reserve in Guatemala, is that of laser scanning.

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>
