Answer:

A stop Codon is the last sequence of base pairs (A,T,C,G) that tells when a new protein and amino acid are formed.

Answer:

In the genetic code, a stop codon (or termination codon) is a nucleotide triplet within messenger RNA that signals a termination of translation into protein

Explanation:

Proteins are based on polypeptides, which are unique sequences of amino acids. Most codons in messenger RNA (from DNA) correspond to the addition of an amino acid to a growing polypeptide chain, which may ultimately become a protein. Stop codons signal the termination of this process by binding release factors, which cause the ribosomal subunits to disassociate, releasing the amino acid chain. While start codons need nearby sequences or initiation factors to start translation, a stop codon alone is sufficient to initiate termination.

In response to a steak dinner, certain secretions are needed to aid digestion. What cells in the pancreas would provide these se
laila [671]

Acinar cells

Yes, CCK would be activated in response to a heavy fat and protein meal, which would then drive a pancreatic secretion that is rich in enzymes.

<h3>What do Acinar cells do ?</h3>

Nearly all of the digestive enzymes required for nutrition digestion that are active in the small intestinal lumen are synthesised and secreted by pancreatic acinar cells. To ensure a sufficient supply of digestive enzymes, both synthesis and secretion are tightly controlled over short and long time scales.

  • The exocrine pancreas's role. The centroacinar cells and intercalated duct cells release a biocarbonate-rich buffer solution, whereas the acinar cells create, store, and release digesting enzymes.

Do you think evolution is still taking place in the Galapagos finches? Why or why not? .
erik [133]
Yes. Evolution never truly stops. There are always variations happening in the environment that organisms must adapt to in order to maintain homeostasis. t is a marker of time on all living matter. As time goes on, the world changes and so does the live that is sustained by it. I hope that this is the answer that you were looking for and it has helped you.

The key to the evolution of altruism is that a. recipients have to be more likely to carry the altruistic allele than nonrecipie
cupoosta [38]

Answer:

The correct answer is b. actors have to be more likely to carry the altruistic allele than non actors.

Explanation:

Altruism is the behavior by an organism that benefits other organisms by costing its own fitness. The actor is the individual who is doing altruism and the recipient is the individual who is getting benefited by the actor's altruism.

An example of altruistic behavior can be seen in animal kingdom easily. Vampire bats give blood to those members of the community who were not able to go for search for blood show altruistic behavior.

Actors have altruistic genes that suggest them to behave altruistically. Non-actors may not contain alleles of altruism but the recipient might have altruistic alleles.

Hamilton's rule says that natural selection will favor the altruistic allele when rb > c.

where r = coefficient of relatedness between donor and recipient

          b = benefit received by recipient and

          c = cost paid by altruist.

Therefore, the correct answer is b.
