Which statements are true for dna and rna? check all that apply?
LekaFEV [45]
Since there are no given choices, I would just compare and contrast DNA and RNA. These are the two types of nucleic acids in the human body. The structural unit of nucleic acids are composed of repeating units of monomers called nucleotides. Nucelotides are composed of three functional groups: sugars which are specifically pentoses (5-Carbon sugars), phosphate group and nitrogenous base.

Now, the RNA and DNA differ in the composition of these sugars and the bases. Based on the nitrogenous bases and sugar, the DNA has a deoxyribose as the sugar and its 4 bases are adenine, guanine, cytosine and thymine. For RNA, the sugar is ribose while its 4 bases are <span>adenine, guanine, cytosine, and uracil.

They also differ in their structure. </span>DNA is a double stranded β-helix with a long chain of nucleotides. RNA is composed of a shorter chain with a single strand α-helix structure.

Lastly, they differ in their functions. T<span>he DNA is responsible for storing the genetic information while the RNA is responsible for transporting the genetic information to the ribosomes which synthesize proteins.</span>

Artist 52 [7]

Answer: Option (3)

Explanation: In between the year 1994 to 1996, a sum of 38 number of sink holes have been found, which could be the resultant of the mining activities carried out in those two years in that particular area

                         In the mining area, drilling and other construction and excavations are carried out through which the water must have percolated down to the rocks like limestone, dolomite which has the ability to get dissolve when comes in contact with water. So this huge number of sink holes have occured there in that time period.

Describe how the lack of water in an environment can affect the amount of carbon dioxide absorbed by the plant.
Nezavi [6.7K]

The direct effects of increased carbon dioxide (CO2) on plant growth refers to the change in plant grow with the levels of temperature, precipitation, evaporation and growing season at their present values. The indirect effects include the results of any changes in the other variables which affect plant growth that come as a result of the effect of increased CO2 on global climate.
