The base composition of an rna virus was analyzed and found to be 14.1% a, 14.0% u, 36.2% g, and 35.7% c. would you conclude that the viral genetic material is single-stranded rna or double-stranded rna? 2. the genetic material found within some viruses is single-stranded dna. would this genetic material contain equal amounts of a and t and equal amounts of g and c?

The correct answer will be -

1. Genetic material of virus is- dsRNA

2. ssDNA does not have equal amount

Explanation:

According to Chargaff's rule the amount of Adenine=Thymine/Uracil and Guanine=Cytosine in the double-stranded DNA or RNA.

If the content of A and U are equal that is 14.1% and G and C are almost equal therefore it follows the Chargaff rule and thus the genetic material is the ds RNA molecule.

The Chargaff rule is not applicable where the genetic material is single-stranded so if the material is single-stranded therefore the A is not equal to T and G is not equal to C.

Thus, dsRNA and ssDNA does not have equal amount is the correct answer.

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
