Answer: The early earth environment was having hydrogen in abundant amount. the early atmosphere was full of methane, ammonia, hydrogen sulfide and water. Today the atmosphere contains 0.03% of carbon dioxide in the environment which was higher in the early days of life. There was no life because of less amount oxygen in the environment.
Now the environment is full of oxygen and has less amount of carbon.
When a disease kills a large amount of the rabbit population which is the competition among wolves most likely. So, the correct answer is (B).
Competition is the interaction of individuals that fight for a common resource which is in limited supply, but more likely can be defined as the direct or indirect interaction of organisms which leads to a change in fitness when the organisms share the same resource. This results in the negative effects on the weaker competitors.
There are three forms of competition among the animals. Out of three. two of them , interference competition and exploitation competition, are categorized as real competition and the third form is apparent competition which is not a real competition.
Interference competition occurs directly between different individuals but exploitation competition and apparent competition occur indirectly between different individuals.
Thus, when a disease kills a large amount of the rabbit population which is the competition among wolves most likely. So, the correct answer is (B).

Answer: 10 million colonies
The volume of media used is 0.1ml and the concentration diluted to 10^-5, so the actual volume used would be: 0.1ml * 10^-5= 1ml * 10^-6
The media shows 10 colonies. The number of colonies per volume would be: 10 cfu/ (1ml * 10^-6)= 10* 10^6 cfu/ml= 10 million cfu/ml

Correct answer: A). Detailed research with reliable sources
Science is a collection of systematic knowledge that is acquired through study and organizing gained knowledge in the form of testable interpretation and prognostication about the universe.
The science tries to relate the knowledge to the facts that follow objective laws and whose development need systematization and method.
Hence, the correct answer would be option A.

Answer:
D. deamination of cytosine to uracil
Explanation:
Hydrolytic DNA damage is usually a consequence of metabolic reactions and the most common example of this type of damage is hydrolysis of cytosine into uracil with the release of ammonia. This damage can be fixed by the cell's DNA repair system:removal of uracil by an enzyme uracil-DNA glycosylase and consequently generation of an abasic (AP) site. AP endonucleases recognise AP site and break a phosphodiester bond so that lesion can be replaced with another cytosine.
