Creation Moment 4/6/2023 - Romans 8:22...Literally

For we know that the whole creation groaneth and travaileth in pain together... Romans 8:22
 
"In new research, biologists recorded ultrasonic sounds emitted by
tomato and tobacco plants inside an acoustic chamber, and in a greenhouse, while monitoring the
plant’s physiological parameters. They developed machine learning models that succeeded in identifying the condition of the plants, including dehydration level and injury, based solely on the emitted sounds. The frequency of these sounds is too high for human ears to detect, but they can probably be detectable by other organisms such as insects, mammals, and possibly other plants
Plants show significant changes in their phenotypes in response to stress. They differ visually, with respect to both color and shape, from unstressed plants.....the ability of plants to emit airborne sounds — that could potentially be heard by other organisms — has not been sufficiently explored. Even in a quiet field, there are actually sounds that we don’t hear, and those sounds carry information...There are animals that can hear these sounds, so there is the possibility that a lot of acoustic interaction is occurring.
They stressed the plants via two methods: by not watering them for several days and by cutting their stems.
The plant sounds resembled pops or clicks, and a single stressed plant emitted around 30-50 of these clicks per hour at frequencies of 40-80 kHz and seemingly random intervals, but unstressed plants emitted far fewer sounds.
Water-stressed plants began emitting noises before they were visibly dehydrated, and the frequency of sounds peaked after 5 days with no water before decreasing again as the plants dried up completely. The types of sound emitted differed with the cause of stress." SciDaily
