Yes, you are right. A student reported that a limp stalk of celery became crisp when placed in ice water. This is an example of an observation.

Observation is the process of actively acquiring information from a source of study. When the observation is collected using the senses, it becomes an empirical evidence. However observations are also scientifically recorded using various scientific instruments for precision and accuracy. Example, use of thermometer to record the room temperature.

The answer is definitely "AN OBSERVATION" I just completed the lesson so I know for sure that this is the correct answer. Hope I helped!

humans can cause extinction of a species through overharvesting, pollution, habitat destruction, introduction of invasive species (such as new predators and food competitors), overhunting, and other influences. explosive, unsustainable human population growth is an essential cause of the extinction crisis.

i didn't have the answer choices , but i tried my best.

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion
