In some third world countries "cyanide fishing" for aquarium trade is allowed. Cyanide fishing uses the cyanide to "stun" fish a
nd make them easy to catch. But the cyanide combined with handling stress has led to a mortality rate in the captured fish somewhere between 60% and 80%. Knowing this, how might this method impact the environment? Cyanide is a safe chemical, so there will not be any effect on the environment. B) Increase cyanide levels in the water will increase the biodiversity in that area.
C) Since so many fish are being caught, there is more room for predators to flourish.
D) It could lead to overfishing, since more fish have to be caught due to the high mortality rate.
The best answer would be letter D, it could lead to over-fishing, since more fish have to be caught due to the high-mortality rate.
Cyanide fishing is actually one of the greatest threats within the oceans and seas. It is a quick-fix solution that humans have resulted to in order to gain more profit. As a result, the environment of species in the water are directly affected.
A Organism, but I would say Multi Cellular Organism instead of just organism because a Unicellular organism only has one cell, and all higher levels are made of multiple cells
Lasers can be used in surgical operation such as eye surgery because they are so precise.
The laser can be used in microscopy to produce very clear visuals and study very minute substances.
Lasers can be used in navigation also due to their precision hence reducing accidents
We use lasers to scan barcodes in supermarkets
Powerful lasers can also be used or security purpose for shooting down flying objects that can cause damage to humanity, such as missile and asteroids.
A phenomenon called laser cooling has been used to trap an atom and assist in its study so scientists are able to understand the universe.
