Answer:

The correct answer will be- newly synthesized polypeptide

Explanation:

The process of translation or the synthesis of proteins takes place in the ribosomes which provide a site for the synthesis of polypeptides.  The ribosomes are made up of two subunits: small and large subunits which provides slots namely A, P and E sites.

The tRNA brings specific amino acid corresponding to the codon of the mRNA and during elongation, the tRNA molecule moves from A site to P site to E site.

The component which exits the exit tunnel is the formed polypeptide chain which exits from the E or exit site.

Thus, the newly synthesized polypeptide is the correct answer.

For many generations, the following genotypic frequencies were observed in a large population of dinosaurs: 4 percent AA, 32 per
Usimov [2.4K]

Answer:

C) 19.7%

Explanation:

The new population distribution after climate change wiped out homozygous recessive dinosaurs is:

AA = \frac{4}{4+32}=\frac{1}{9}

Aa = \frac{32}{4+32}=\frac{8}{9}

The percentage of offspring of this new population that are homozygous recessive is given by:

P(Aa\ x\ Aa) = \frac{8}{9} *\frac{8}{9} =\frac{64}{81} \\P(aa) = \frac{1}{4}\\P(Aa\ x\ Aa) \cap P(aa) = \frac{64}{81}*\frac{1}{4} =0.197=19.7\%\\

19.7% of these newborn dinosaurs died

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.
