Where's the evolution?
The physics of light affects not just how blue water looks to us, but how the animals living in the world's oceans, lakes, and rivers are able to find food and each other — and this, in turn, can impact their evolution. Natural selection favors traits that perform well in local environmental conditions. Many fish species, for example, have evolved vision that is specifically tuned to see well in the sort of light available where they live. But even beyond simple adaptation, the physics of light can lead to speciation. In fact, biologists recently demonstrated that the light penetrating to different depths of Africa's Lake Victoria seems to have played a role in promoting a massive evolutionary radiation. More than 500 species of often brightly colored cichlid fish have evolved there in just a few hundred thousand years!
Answer:
I've got no idea what you're asking but my guess would probably be. . . C?
Best Answer: Well, you have to look at the onion slide under the microscope and looks at each cell and tell what stage (interphase, prophase, etc.) they are in. and then for the description probably tell which one there is the most of and maybe why you think that is. You can find pictures of each phase in your book. I did a lab like this not too long ago in my bio class lol. And, i believe that you will get a lot in interphase (when cells are not currently dividing), just to let you know.
<h2>A) option is correct </h2>
Explanation:
- RNA is a linear polymer of ribonucleotides
- Sugar in RNA is ribose instead of deoxyribose which is present in DNA
- The four nitrogenous bases present in RNA are adenine, cytosine, guanine and uracil whereas that in DNA are adenine, cytosine, guanine and thymine
- RNA molecules carry genetic information from DNA to proteins, cannot transmit from one generation to next generation as a genetic material
- Due to steric hindrance by the 2'-OH group of ribose sugar, RNA unable to form double helix
