Explain why organisms are more likely to be well preserved in mud than in sand? Justify your response in
xenn [34]

Answer:

Explanation:

Organisms are well preserved in mud because mud has high water holding capacity. It retains water and does not allow oxygen flow which can destroy the remains of organisms. There are some microbes that preserved whose growth are enhanced in water related environment like mud.

But sand cannot retain or hold water. It drains it off and all oxygen bearing water to flow which enhance decay compared to mud. It can't preserve organisms because of the above reasons.

You have identified two mutants with same phenotype.
algol13

Answer:

No, there are multiple ways in which different mutations in the same gene can cause the same phenotype

Explanation:

Several different mechanisms of mutation can lead to the same phenotype. For example, lets say our phenotype is that flies have white eyes, and we know that this occurs in one particular gene that normally makes the eye colour red. (the red gene)

These mutations likely rendered the red gene ineffective (as the eyes are not red). However, this could happen in a variety of ways.

  • There could be a single base deletion in the first exon of the mRNA, changing the reading frame of the protein and messing up the entire sequence (a frame shift mutations)
  • The entire gene could be deleted
  • A single base could be substituted in an important site of the gene, for example, one which translates into a catalytic residue or binding site in the protein
  • There could be an inversion at the promoter region of the gene, such that a transcription factor can no longer bind to transcribe the gene.

There are countless other ways in which a mutation could have been caused. Therefore, just because we know the same gene is affected does not mean that we can assume the mutations are identical.
