Question 1:
Exons are gene fragments whose DNA sequence after transcription is found in mature mRNAs. This part of the gene is most often coding.
The size of the exons in the genomes follows a log-normal distribution, with an average length of about 150 nucleotides, knowing that in eukaryotes, each gene contains several exons and introns (an average of 8) so the size is 8*150 = 1200 bp.
Question 2:
Introns are fragment of a gene located between two exons. Introns are present in immature mRNA and absent in mature mRNA. "Non-coding" fragment of the gene.
The introns average in a gene is 3365 bp including 3'UTR and 5'UTR and intermediate introns.
Answer:
they dont get eaten by other fish
since she is holding them and not as many are getting eaten there will be a biggier chance of the population rising
Explanation:
The answer is Speciation cannot occur in the absence of mutation. Speciation cannot occur in the absence of natural selection
The ground will get wet and the seeds will sink in the ground then t ground will dry up and the seeds will get stuck
Platypus is an Australian mammal that lives in deciduous forests. Platypus's bill is adapted in order to allow platypus to travell and find its way in the river without using vision. This adaptation is achieved through special receptors that sense touch and electricity. Platypus's feet are webbed, enabling them to swim fast and efficiently and move easily on muddy surfaces.
