Answer:
The sequence from least damaging to most damaging is silent, missense, frameshift, and nonsense mutation.
Explanation:
A silent mutation refers to a modification in the sequence of nucleotide bases that constitutes DNA, however, it does not result in a substantial change in the amino acid or in the function of the entire protein. In missense mutation, one DNA nucleotide gets switched out with another one in a manner, which modifies the specified amino acid.
When a missense mutation takes place in the molecule of DNA, it changes one of the sequences of RNA codon produced at the time of transcription. A frameshift mutation refers to a specific kind of mutation, which comprise either deletion or insertion of the additional bases of DNA. Following the mutation, the entire sequence of DNA will be read incorrectly.
A nonsense mutation refers to a genetic mutation in the sequence of DNA, which leads to the formation of the shorter or unfinished protein product. This mutation takes place when an undeveloped nonsense or stop codon gets presented in the sequence of DNA.
Thus, the silent mutation is the least damaging as it does not exhibit any influence on the function or composition of the protein. While nonsense mutation shows the most damaging effect as it results in an abrupt termination peptide chain.
Answer:
D!!! pesticides are used to keep bugs off from plants! they're all correct! GMO's are used for all of that
Role of decomposer in fooe chain/food web
Decomposers are organisms which convert complex organic molecules into their simple forms.
Example
bacteria, fungi etc.
Explanation
food chain stary from autotrophs and end at decomposers. these organisms are present in soil, rely on dead bodies of plants and animals for their nutrient requirements. These organisms possess strong enzymatic system, which scavenge comples molecules from dead bodies during respiration and convert them into simple nutrients which return back to atmosphere.
The third choice is the answer.
This is because chemical change occurs when the (for a lack of better wording) interior of the object is changed in the second one the bread is being broken down chemically by the stomach acid this is because the acid is breaking down the formation of the bread dissolving it and chainring it into something else.
In the 4th one the change that is seen is chemical because the formation of the roof is change the physical appearance may be the same (ie. The size & shape) but their are other changes in the color, texture and maybe taste ( don’t taste a rusting roof lol) these are ways in which you can figure out if a change is chemical or physical.
Physical change occurs when the size and/or shape of an object is changed.
Chemical change occurs when the texture, taste and/or color of the object is changed, but-sometimes chemical change cannot be seen.
Hope this helped :)
Answer:
D. it takes millions of years to form
