Coal is formed when layers of plant matter accumulate at the bottom of a body of water and are protected from biodegradation and

oxidization. Over time, the properties of the original material change. What evolutionary significance, if any, does this have?

The evolutionary significance is that coal does not change the properties of the plant from that time even though the plant might have evolved from that time. That's why you can study coal to find out how the type of plant was at that time period and how it has evolved until now.

Which of the following sequences shows a frameshift mutation compared to the wild-type mRNA sequence?
Butoxors [25]

Option C:

B. wild-type 5-AUGCAUACAUUGGAGUGA-3 mutant 5'-AUGCAUACAUCUGGAGUGA- 3' 

Explanation:

A frameshift mutation is a genetic mutation such that the triplet nature of gene expression by codons, the insertion or deletion occurs in such as way that it alters the complete sequence of 3 codon sets and can change the reading frame, resulting in a completely different translation from the original.

As it is pertinent to understanding that all genes are normally translated in sets of 3 codons, which typically describes and explain a unique amino acid sequence. Thus, if a frame shift mutation occurs, it can affect many amino acid sequences and finally the entire protein.  

If we look at option B:

wild-type 5-AUG   CAU  ACA  UUG  GAG  UGA-3  

mutant 5’-    AUG   CAU  ACA  UCU  GGA  GUG  A-3’  

An insertion of a base Uracil showed at the end of 3rd codon which affected and altered the whole sequence of codon triplets. This changed all next codons and finally all next amino acids will be altered.

The administration method that takes the longest time for the drug to reach the brain is __________.
photoshop1234 [79]

Oral ingestion or swallowing is the administration method that takes the longest time for the drug to reach the brain. When using this method, the drug is swallowed through the mouth, moves to the stomach and then into the bloodstream before it can be transported to the brain. This means that it takes longer for a swallowed drug to start functioning than it does with other methods of administration such as injecting.
