Answer: B. evaporation, condensation, precipitation
Explanation:
The cycle that ensures that fresh water is available is called the Hydrological cycle and it involves several key processes.
As it is a cycle, none of the processes can be considered first but if any could, it would be evaporation. This is when water on the surface is heated and becomes water vapor (gas) and rises towards the atmosphere.
Condensation occurs as the water vapor rises because the further up you go, the colder it gets. These water vapor particles will thus condense and clump together to form clouds.
These clouds keep getting larger until they are too heavy to be carried by the atmosphere in which case they fall to the ground as rain the process known as precipitation.
Answer:
B) oaks and other sexually reproducing, extant (currently living) trees
Explanation:
The biological species concept defines the species on the basis of their reproductive isolation. It states that when individuals are able to interbreed to produce fertile and viable progeny, they belong to the same species. The members of different biological species cannot interbreed. If they interbreed, either pre-zygotic or post-zygotic isolation mechanisms do not allow the production of fertile progeny.
Therefore, the biological species concept can be applied to the organisms that are able to reproduce sexually. The asexually reproducing organisms would not exhibit any reproductive isolation which is a key criterion to group organisms under different species. Among the given examples, biological species concept can be applied to the sexually reproducing extant trees such as oak.
Since we cannot deduce the reproductive isolation in sexually reproducing extinct species, the concept is not useful for dinosaurs which are extinct now.
Answer:
In science, accepted theories do not represent absolute truths. A scientific theory is accepted when there is much evidence available that support its statements, but new lines of evidence can modify original presumptions
Explanation:
A scientific theory is a plausible explanation of a particular phenomenon of the natural world, which has been many times tested and verified by using the scientific method. The accepted theories are progressively modified (or even overturned) as new lines of evidence emerge. In consequence, a scientific theory is composed of statements that we consider as truths regarding the available evidence, but we have no absolute certainty that such statements are true. The ability to self-correct is fundamental in science and it happens when we discover that the original statements of a scientific theory were wrong, thereby new lines of evidence allow us to correct the error and/or develop new scientific theories.
