What is the affect of increasing the temperature of the water?
What happens when you add pollution to the water?
Can coral survive bleaching?
What is coral?
Answer:
Explanation:
Increasing temp in water makes it start to boil and evaporate into the atmosphere, in terms of climate change it makes it hard for many organisms to survive because they have to adapt quickly to the waters rapidly rising temperature. When you add pollution to water the water would become contaminated and not be able to support life or be fit for human consumption.
Coral cannot survive bleaching because it harms the coral to the point of its destruction.
Coral is an animal that can grow into big reefs that create large ecosystems for many organisms. They are in the ocean. The biggest coral reef is the great barrier reef in Australia.
Which type of electromagnetic energy must be used carefully in medicine so it does not damage living tissue?(1 point)
low frequency waves
visible light
radio waves
gamma rays
Among electromagnetic waves, UV rays are most dangerous because exposure to these radiation cause serious problems in living organism. Therefore, gamma rays is used carefully in medicine without damaging living tissue.
What is electromagnetic wave?Electromagnetic wave is a wave which contain two component one is electric component and other is magnetic component. The electric and magnetic component are perpendicular to each other. There are so many wave that comes under electromagnetic wave like infrared wave , radio wave.
There is a relation between energy of wave. frequency of wave, and wavelength of wave
Mathematically,
E=hc/λ
where,
E = energy of electromagnetic wave
h is planks constant having value 6.67×10⁻³⁴js
c is speed of light that is 3×10⁸m/s
λ is the wavelength of electromagnetic wave
There are many uses of electromagnetic radiations in medical field. Gamma rays are used to kill the dead cells from e.g. cancer but they don’t destroy the living cells as gamma is only a wave.
Therefore, gamma rays is used carefully in medicine without damaging living tissue.
