Answer:
A theory<u> is the result of one single well proven and well-accepted hypothesis.</u>
Explanation:
A theory Is the result of one single well-proven and well accepted - hypothesis .
A theory is a well accepted hypothesis which is also well proved , which tries to explain something based on a known principle .
A theory can have one or more hypotheses that are supported by some repeating testing .
A theory can never be shown as wrong in any context , and if it is wrong , then the theory is widely disproven .
Theories can even derive and evolve , and does not imply the older theories to be wrong , new discovered experiments or idea just get added to the previous theories.
Answer:
(C) The reaction between dissolved carbon dioxide and carbonate ions to form bicarbonate significantly enhances the ocean’s capacity to store carbons.
Explanation:
ocean consumes mainly carbon dioxide from atmosphere. This is done by the process of photosynthesis performed by the plants like organisms in the sea known as phytoplankton. Through this process carbon dioxide dissolves in water further reacting with sea water creating carbonic acid. This carbonic acid leaves hydrogen ions which later combines with carbonate to form bicarbonate. The result of formation of bicarbonate increases the capacity of sea to store the carbon which doesn’t escape the ocean easily.
So option (c) will be correct answer
Answer:Fossil Record
Explanation:
Fossils provide evidence that organisms from the past are not the same as those found today, and demonstrate a progression of evolution. ... The resulting fossil record tells the story of the past and shows the evolution of forms over millions of years.
Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood, oil, coal, and DNA remnants. The totality of fossils is known as the fossil record.
The fossil record, however, is quite incomplete. Here's one major reason why: Sediment has to cover an organism's remains in order for the long fossilization process to begin. ... So like the mineralized bones themselves, the fossil record is an incomplete framework that scientists flesh out through additional methods.
Answer:
The change of one type of matter into another type (or the inability to change) is a chemical property. Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion.
hope this helps :)
