For the answer to the question above for property damage, one example we could give is buildings or houses. Erosion decreases the value of this properties because the materials like metal are oxidizing and rust overtime and the structure's strength is decreasing over time. As for damage to crops. the land's nutrients decrease overtime too. Which means the crops can get fewer nutrients from the soil in order to perform Photosynthesis.
The long-term effects of this things on humans are things get riskier. Like a car. A 20-year-old car isn't the same as a brand new car in whatever ways. The brand new cars are safer because the materials that are used there are newer than the old car and they are more reliable. Same for humans. A 5-year old's health is not the same as a 50-year-old's health.
Echolocation is also called bio sonar. It is the sonar used by several kinds of animals that <span>enables them to locate and discriminate objects by projecting high-frequency sound waves and listening for echoes as the sound waves reflect off objects. </span>
Dolphins and whales make these sounds at any time and at considerable depths. Sounds vary in volume, wavelength, frequency, and pattern.
The wavelength depends on the speed of
propagation (c).wavelength=c/f The speed of sound in water is c= 1450 m/s.
So, for bottlenose delphins the wavelength is:1450m/s / 110.5 kHz
1450 m/s / 110500 Hz =0.013 m = 0.13 mm
For whales the waveleng42.5 th is:1450m/s / 42.5 kHz =
1450m/s / 42500 Hz= 0.034 m = 0.34 mm
Answer:
An active transport requires energy, a passive transport does not.
That's all! Hope that helps :)
Answer:
Trees and birds have a commensalism relationship. The birds benefit from having a place to build their nests, while the trees are unharmed and not impacted by the bird’s presence.
