Answer:
Because that is when oil and other harmful fumes to ecosystems first started appearing, and they did not care about animals back then as much, an example could be when they sprayed pesticides to kill weeds but instead almost killed a huge bird population. Most marine animals did not start dying and becoming endangered species until we did many oil spills into the ocean.

hope this helped i want to be a marine biologist when i graduate uwu
<h2>KDEL Sequence & Protein Unfolding</h2>
Explanation:
(a) The distinction between proteins sent out from and those held in the ER has all the earmarks of being represented by two unmistakable sorts of focusing on successions that explicitly mark proteins as either bound for transport to the Golgi or bound for maintenance in the ER. Numerous proteins are held in the ER lumen because of the nearness of the focusing on grouping Lys-Asp-Glu-Leu (KDEL, in the single-letter code) at their carboxy end. In the event that this succession is erased from a protein that is regularly held in the ER (e.g., BiP), the transformed protein is rather moved to the Golgi and emitted from the cell. On the other hand, the expansion of the KDEL arrangement to the carboxy end of proteins that are typically discharged makes them be held in the ER. The maintenance of some trans membrane proteins in the ER is comparatively directed by short C-terminal successions that contain two lysine deposits (KKXX sequences)
(b) Proteins are large molecules composed of folded chains of amino acids. Every protein has a unique shape and that shape determines the things it does. You could think of them as keys that fit into certain locks around the body Proteins do lots of different things around the body, including speeding up biological processes, recognizing antibodies, providing structure to certain body parts, transporting substances, regulating genes, and responding to signals inside and outside the body Proteins range in size from small ones, such as insulin - only 51 amino acids long, to extremely large ones, such as titin almost 27,000 amino acids long. No matter their size, they must be folded into a particular shape in order to function. Sometimes, though, things go wrong and cause the protein to unfold
The probability that their son exhibits the 'color blind' trait is 0%. It is a type of inheritance linked to the X chromosome.
<h3>Inheritance linked to the X chromosome</h3>
In men, the patterns of inheritance linked to the X chromosome don't follow conventional mendelian inheritance because men have only one X chromosome.
Conversely, women have two X chromosomes, thereby the inheritance pattern resembles Mendelian inheritance.
It is important to highlight that color blindness is a recessive trait on the X chromosome.
In this case, the mother is a carrier, thereby the probability of passing this trait as a carrier to her son is 50%, whereas the father is normal, thereby the probability of passing this trait to his son is 0%.

How has selective breeding changed the wolf into the many different breeds of domestic dogs that we know today?
a. Animals with the traits that were desired were bred to each other.
b. As civilization changed, so did our need and desire for different types of dogs.
c. The fear of humans was bred out of wild wolves.
d. All of the above.
It is the ribosomes that assist tRNA
