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>
Answer:
there was hunting and destruction of there habitats
Answer:
Viruses may be defined as the organisms that shows the border line between the living and non living organisms. Viruses can only replicate when they enter in the body of a particular host.
Viruses are pathogenic for humans and can cause deadly diseases like AIDS. The pandemic condition of virus mainly depends on the the matter of time. The appearance of the disease condition before the occurrence of the another disease.
Answer: Determined by genetic and environmental factors.
Explanation:
Are determined by genetic and environmental factors and the interaction of such factors, but not with absolute certainty. This development system model includes both influences of species typical genes and the influences of a species typical rearing environment. Relatively rapid increase in obesity, the change stems from changes in the environmental context.
