What would happen if rats was eliminated from the environment
erma4kov [3.2K]

Rats account for a decent amount of biomass globally.  They are intermediate predators, eating a lot but also being eaten.  If they went extinct, they would stop eating many insects and seeds / fruits -- the former would gain significantly in population, and the latter would lose some of their pollination.  Both factors would harm the viability of at least some species of plants, by adding to plant eaters (insects) and reducing plant reproduction.  Rats' predators would also suffer if they went extinct.  The primary predators are birds of prey, such as hawks and owls.  However, other animals such as skunks, foxes, weasels, coyotes, and even wolves eat rats.  For predators in marginal environments, the loss of such a food source could drive them out of a habitat area.

Select the phrases that accurately describe properties of the most common form of the DNA double helix. There is more than one c
zhuklara [117]

Answer:

A strand of DNA comprises pyrimidines, that is, cytosine and thymine and purines, that is, adenine and guanine. Of these pairing takes place between thymine and adenine and guanine and cytosine. Thus, it can be said that in DNA, the amount of adenine is corresponding to thymine, and the concentration of guanine is corresponding to cytosine. Hence, the given first statement is correct.  

DNA gives an appearance of a helical structure, in which each of the helices comprises approximately 10 nucleotides within them. Hence, the given second statement is also correct.  

The strands of DNA found in a helical structure are complementary to each other, or it can also be stated that the nucleotides present in one strand of the DNA are found in opposite direction and orientation with respect to the second strand of the DNA. The phosphodiester bonds play an essential function in combining a molecule of sugar of one nucleotide with the molecule of phosphate of the adjacent nucleotide. Hence, the given fourth statement is also correct.
