Answer:
The correct answer is option B, that is, less genetic diversity in later generations.
Explanation:
A pandemic that spread across Europe between 1348 and 1350 was named as the Black Death. It has been predicted that of the total population of Europe at that time 30 to 60 percent died due to the pandemic. The geneticists are still trying to document the influence of Black Death on the population of Europe today.
It has been found that in England, the genetic diversity is found much lower in comparison to what it was in the eleventh century, and is primarily due to so many people dying in the 1300s. However, the rest of Europe does not demonstrate a dropped amount of genetic variation, which maybe because of the enhanced patterns of migration in other places.
The answer should be A: by consuming plants or other animals. Sorry if I am mistaken though... Please mark me as brainliest if i was helpful!
Good luck and have a great day! :)
The base found in RNA nucleotides, but not in DNA, is uracil.
RNA and DNA share three bases: adenine, cytosine, and guanine. However, for the fourth base, DNA has thymine while RNA
has uracil. When forming base pairs, cytosine bases are matched with guanine, while adenine bases are matched with uracil or thymine.
Although tube worms cannot produce their own food, they often thrive around these underwater vents. They are able to survive because inside the tube is the trophosome, an organ that contains millions of bacteria in symbiotic relationship with the worm, which are responsible for feeding these creatures that do not have any type of digestive system or visual organs, as they live in the most absolute darkness.
