Answer: Availability of water
Explanation:
When a person is travelling from a forest ecosystem towards grassland ecosystem the number of trees gets reduced in number.
The trees are replaced by prairie grasses. This change is because of less water availability in the area having grass.
The amount of precipitation decides the type of vegetation found in that area.So the area having trees would be having more precipitation as compared to the area having prairie grass.
Answer:
The correct answer is - DNA --> RNA --> amino acid --> protein --> phenotype.
Explanation:
DNA encodes for the RNA and RNA encodes for the proteins in the process of central dogma to produce protein in two processes called transcription and translation to produce protein.
It begins with encoding DNA into RNA (mRNA), known as transcription, which is moved to the ribosome to translate into amino acid chains with help of tRNA and makes a specific protein which could be a form of genotype which express itself to produce a specific trait that makes a particular phenotype of that trait.
A exon is a portion of your dna that is expressed as a gene
the introns are just space in between the exons that are cut out during transcription
A large portion of your DNA is a bunch of nothing which is believed to have been caused by retroviruses that inserts its DNA into yours. These introns serve as a huge benefit to us as they are what keeps our genes from getting all screwed up from all the random mutations that happen in our DNA. Since more than 95% (Most likely more don't really remember) is introns a mutation happening on any part of your dna is most likely to happen on the intron which is not expressed. The exons are the expressed dna which are your genes. These are the parts that are used to manufacture the proteins in your body
