Answer:- Decomposition

Explanation:-

Decomposition is a natural process that occurs in the environment to break down organic substances into simpler substances.

All the living organisms that die, are decomposed and their bodies are broken down into simpler substances such that the nutrients are released into the soil.

The plants are then able to absorb these nutrients from the soil and thus, the nutrient cycling goes on as the organisms feeds on it.

Not only the dead animals but also the fallen leaves and other parts of the plant gets decomposed as they die.

The process of decomposition is carried out by living organisms present in the soil such as bacteria. Such organisms are called as decomposers.

Answer:

A mutation that changes the first letter to 'C' is called Frameshift mutation.

Explanation:

FRAMESHIFT MUTATION -: A frameshift mutation is a genetic mutation of a number of nucleotides caused by indels (insertions or deletions) in a DNA sequence that is not divisible by three. A frameshift mutation (also called a framing error or a reading frame shift) The addition or deletion may alter the reading frame (the grouping of codons) due to the triplet nature of gene expression by codons resulting in a completely different translation from the root. A frameshift mutation, instead of being added or removed, is not the same as a single-nucleotide polymorphism in which a nucleotide is substituted. In general, a frameshift mutation will cause the reading of the codons to code for various amino acids after the mutation. The first stop codon ("UAA", "UGA" or "UAG") encountered in the series would also change the frameshift mutation. The polypeptide that is formed will be abnormally short or abnormally long, and most likely will not be functional.
Hence, the answer is Frameshift Mutation.

Miller's classic experiment demonstrated that a discharge of sparks through a mixture of gases could result in the formation of

beks73 [17]

Answer:

The correct answer will be-gas absent in primordial atmosphere (oxygen).

Explanation:

The Miller experiment was performed in 1953 to show that organic molecules can be formed from the inorganic molecules in the conditions resembling the primordial atmosphere.

Same conditions were created to the unstable atmosphere like a mixture of gases which included- methane, sulfur dioxide and hydrogen but lacked oxygen as it was absent in the primordial atmosphere.

Thus, gas absent in the primordial atmosphere (oxygen) is the correct answer.
