Answer: Option A) sinkhole formation.
Explanation:
A sinkhole refers to any dug-out or depressed area of land where human
or animal waste (excreta) are deposited.
Now, since these wastes contains water and are biodegradable by microorganisms, the fecal matter could be infected and in turns infect groundwater.
The contaminated-groundwater poses danger due to disease-causing organisms like
- vibrio cholerae, causing cholera
- Salmonella typhi, causing typhoid outbreak present, and also reduces volume of suitable drinking water in the community
Thus, the answer is sinkhole formation
Redi and Pasteur were both trying to disprove the hypothesis of spontaneous generation that stated that a living organism can emerge from inorganic matter or dead flesh. Therefore, it was essential for their research to completely seal their vials and prevent contamination with living things and spores from the environment in order to prove that living things do not emerge spontaneously.
Answer:
there have been several cases where fossils of the same type and age where found on different continents.
For example:-
"The Mesosaurus" which is an extinct genus of reptile from the Early Permian and was found in the continents of southern Africa and South America.
This seems to point to the fact that once all the continents were togethe, and they are now separate due to the Continental drift. ( the theory that states that all the continents were earlier one big form of landmass, but they have moved away from each other thus appearing to have "drifted" across the ocean bed."
But again these are all just theories and speculations but findings like these strengthen them and make people believe in these theories. They haven't exactly been confirmed. Like the evolution theory.
i hope this helps.
have a great day ahead :)
