Answer:

<h2>Coevolution</h2>

Explanation:

Coevolution : It is the influence of closely associated species on each other in their evolution, they affect each other.

In coevolution , two or more species reciprocally affect  evolution of  each other by natural selection.

 

Coevolution Examples:

There are lots of examples of coevolution, some are here

i) coevolution of Predator-Prey , this relationship is one of the most common examples of coevolution.

ii) coevolution of  Herbivores and plants,

iii)  coevolution of Acacia ants and Acacias and

iii)  coevolution of Flowering Plants and Pollinators and many others.

What happens if a person goes into a black hole?
Alona [7]

Explanation:

we all find ourselves confronted with the age-old question:

what happens when you fall into a black hole?

You might expect to get crushed, or maybe torn to pieces. But the reality is stranger than that.

The instant you entered the black hole, reality would split in two. In one, you would be instantly incinerated, and in the other you would plunge on into the black hole utterly unharmed.

Hope this helps you.. Good Luck

Smilin is a (hypothetical) protein that causes people to be happy. It is inactive in many chronically unhappy people. The mRNA i
Studentka2010 [4]

Answer:

The single nucleotide mutation affects the splicing of the mRNA molecule of Smilin in unhappy people. This with result in a truncated protein lacking part of it amino acidic chain

Explanation:

It's true that the information of aminoacids that form the proteins is codified on the exons, but introns also have important information, for example, the sequences related to the splicing of the mRNA exons.

Briefly, during the splicing process, the introns are removed, leaving the mRNA that is going to be translated (there could be also other post translational modifications before going to ribosomes).

Also, there's different ways to splice the different exons. For example, let's say a mRNA has four exons, so the mature mRNA could have exons 1-2-3-4, or 1-2-4, or 1-2-3, it depends on the location of the splicing signals. This are called splicing alternatives, so the same original mRNA can give arise to different forms of a protein.

In the particular case of Smilin, apparently the DNA has a single mutation in the intron for the mRNA of the protein. Despite it might seem as a minor difference, it causes the final mRNA (the one that is translated) to lose an internal stretch of 173 nucleotides.

A possible explanation is that this single mutation is affecting a splicing signaling sequence, making the splicing complexes skip one exon. Again, if we imagine that the original protein has four exons, this means that the happy people has an mRNA with all the exons, while unhappy people is lacking one.

As a result, the protein Smilin will be lacking part of its internal region. The actual effects this has on the protein function will depend on the role of the deleted section.
