Scientific theory is what the scientist thinks is correct, but still has room for correction, while a scientific law is proven by experiments over and over again to deem it's correct.
Answer:
The answers are matched as follows:
African forests have been hunted to near extinction levels to obtain ivory-------------->human exploitation
The eruption of mount Saint Helens destroyed some populations of conifers------> natural disasters
An infection with a fungus reduced the population of North American Elm trees ----> disease
Increasing global temperatures have altered migration patterns of humpback whales ------>climate change
If a hypothesis is supported consistently by different observations or experiments, it may be advanced to the level of a(n) <u>theory</u>.
Chlorofluorocarbons
destroy the ozone layer. This, therefore, allows the penetration of Ultraviolet rays from the sun to reach the earth’s
surface. UV rays are dangerous to life on earth due to their capacity to
destroy DNA and cause mutations.
Answer:
The organism that can live deep beneath the earth surface despite intense pressure heat lack of water and sunlight might be Nematodes.
Explanation:
- Nematodes are able to cope extreme heat or extreme cold and dehydration. They have adopted by learning technique that allows them to survive. They can transform into a hardy form called the dauer stage.
- They can survive harsh conditions for longer durations at this stage. And again awaken themselves when conditions are favourable again.
- They can be found in hot springs, deserts, high up mountains and in the deepest oceans.
