Every organism has a unique ecosystem in which it lives. This ecosystem is its natural habitat. This is where the basic needs of

the organism to survive are met: food, water, shelter and a place to breed. All organisms need to adapt to their habitat to be able to survive. Animals and plants with adaptations that make them better suited for the environment will survive and reproduce better than those less suited for the environment. What adaptations are beneficial in the taiga or boreal ecosystem, marked B on the map? Select ALL that apply

Animals dont need to breed to survive for themselves, but they do need food, water and shelter

is that whats being asked? this is a bit confusing

does the presence of introns exons in eukaroytic cells provide more potentia diversity in gene products than is possible in pork
Leona [35]

Answer: Yes. Splicing can be done in different ways to yield different mRNAs wich will create different proteins. Prokaryotes are not able to do this.

Explanation:

DNA (deoxyribonucleic acid) is a molecule that contains the genetic information for synthesizing amino acids that form proteins. To do this, DNA must first be transcribed into RNA (ribonucleic acid) and this is the molecule used for protein synthesis (translation). The newly transcribed RNA (called primary messenger RNA) from DNA results in a very long molecule and also has regions that do not code for anything, called introns, which are removed by a process called splicing. Exons are segments in the RNA that do code for amino acids and remain in the mature mRNA after splicing.

<u>Splicing is a process by which introns are cleaved from the primary messenger RNA and exons are joined to generate mature messenger RNA.</u> In addition, alternative splicing occurs which allows different mRNA isoforms and thus different proteins to be obtained from a primary mRNA transcript. This is because the exons will be joined or spliced in different ways, giving rise to different mature messenger RNA sequences. This process occurs mainly in eukaryotes, although it can also be observed in viruses. But it does not take place in Prokaryotes (Bacteria).

In summary, exons/introns can be spliced together in different ways to yield different mRNAs sequences. Each different mRNA sequence will code for a different protein.

If a mutation occurred that increased the number of exons in a sequence of DNA, what impact would this have on the protein forme
erastovalidia [21]

Answer:

See the answer below

Explanation:

<em>An increase in the number of exons in a sequence of DNA would result in another protein with a longer amino acid sequence.</em>

<u>Exons are the coding part of a gene as opposed to introns. After transcription, the non-coding part of the gene - the introns - are removed by splicing and the exons are joined back together. The final RNA that will undergo translation consists of only exons. </u>

The longer the exons in a gene, the more the codons present in the corresponding mRNA from the gene, and the more the number of amino acids that would be translated from the mRNA. A longer amino acid chain would result in a different protein.

Hence, a mutation that causes an increase in the number of exons in a sequence of DNA would result in a different protein with a longer amino acid sequence.

How does the height of the tropopause change from day to night?
Luden [163]
While the surface temperatures can vary quite a bit, changes in temperature at the tropopause levels change much slower and are tied more to the time of year.<span>
Hope this helped :)
