The correct answer is blank1: quadrant sampling, and blank2: endangered.
Explanation:
A scientist needs to test her hypothesis she needs to perform an experiment or test and for a slow-moving animal (like snail or earthworm) quadratic sampling is a perfect method. The quadrate method uses a closed plot of land to find the vegetation of plant or population percentage of animals present in that land.
A decreasing population of animal could be endangered if the trend will not change.
Thus, The correct answer is blank1: quadrant sampling, and blank2: endangered.
A mass movement can either be slow or rapid. The slow downward movement of materials in a slope is called creep. This happens when the soil loosens up because of water and burrowing animals. In contrast to this, the rapid movement of large materials in a slope is called landslide.
