Head in the Clouds Giraffes are the tallest animals on land. An adult giraffe has a neck that exceeds 2 m in length. This neck enables a giraffe to access food that other animals cannot reach and detect predators from a long distance. Studies have shown that giraffes will browse trees at heights that other herbivores cannot reach. The water and nutrients gained from leaves enhance a giraffe's fitness by increasing survival and reproduction. However, a long neck comes with a cost: the heart mu...

Praxis- Mathematics Questions and Answers 100% Pass In the proceeding figure, P and T are points on like k, and points Q, R and S are points on line l. Lines k and l are parallel. What is the measure of the angle TRS? Since angles PTR and TRS are alternate interior angles, they are congruent and they have the same angle measure. The equation: 5x + 10 + 110 = 8x+102 x=6. The measure of angle TRS is 8 x 6 + 102 = 150 degrees. The following table shows the distribution of 50 cookies sold in a sto...
