Explanation:

A herbivore's back teeth are adapted to help it chew its high fiber plant diet. The front teeth, however, help it actually put the food in its mouth. The picture below shows a typical goat skull (herbivore), and as you can see, it is similar to the one in your problem. So, that skull is one from a herbivore.

In this experiment, researchers placed a pair of lizards from Iron Cay, which has large trees, in an experimental island, which has only small bushes and grass. After several generations, they measured the leg length of 10 lizards from each site. Which group of lizards had longer legs on average?

A. The ones on Iron Cay

B. The ones on the experimental island

C. There is little or no difference between the two samples

D. The difference between the two samples is too large to be conclusive

On average, the lizards from Iron Cay seem to have longer legs than the lizards living on the experimental island. We know this because the sample means + 2 SEMs (the 95% confidence intervals) do not overlap. However, to know whether the difference between the means is statistically significant you would need to use a statistical test like the student t-test

These are composed of intersecting horizontal and vertical lines that form a cartesian plane.

Answers

, The number plane, or Cartesian plane, is divided into four quadrants by two perpendicular lines called the x-axis, a horizontal line, and the y-axis, a vertical line. These axes intersect at a point called the origin. Once a unit distance has been chosen, the position of any point in the plane can be uniquely represented by an ordered pair of numbers (x,y). For the point (5,3), for example, 5 is the x-coordinate and 3 is the y-coordinate, sometimes called the first and second coordinates. When developing trigonometry, the four quadrants are usually called the first, second, third and fourth quadrants as shown in the following diagram.
