RNA and DNA-RNA hybrids are more dense than simply DNA if the density of different nucleic acids is tested using a CsCl gradient.
The primary technique employed in molecular biology is the extraction of DNA, RNA, and protein. Scientists can separate materials according to size, shape, and density by using density gradient centrifugation. Isopycnic centrifugation, a sort of density gradient centrifugation that Meselson and Stahl developed, employed a cesium chloride solution to separate DNA molecules solely on the basis of density. Because DNA has hydrogen bonds between its strands, which makes it less dense than RNA, RNA has a far larger density than DNA. RNA can be obtained at the test tube's bottom using a CsCl density gradient and high centrifugation, whereas DNA can be recovered in the middle layer.

Answer:
The correct answer is - volume.
Explanation:
The volume is the measurement of the quantity of 3 D space that is enclosed by the matter that could be solid gas or liquid. The volume can be measure in the kg³, m³, cm³, l³ and other measurements.
Volume of the gas can measured as the place occupied by a particular matter. It is expressed in units like kilograms, centimeters, and litters.
Thus, the correct answer is - volume.
The correct answer is C. It is reliable because the article is based on multiple studies done by scientists at multiple veterinary schools.
Explanation:
Information is considered as reliable if it is supported by evidence and the author is an expert in the field. According to this, the information about the Labrador Retriever in the encyclopedia is reliable because it is based on multiple scientific studies and articles that likely used evidence such as tests, observations, among others. Besides this, the studies were done by scientists at veterinary schools, which are considered to be experts and authorities in the field of dog breeds. Thus, this source "is reliable because the article is based on multiple studies done by scientists at multiple veterinary schools."
Answer: The answer is C. Order pizza and popcorn and watch more television as a family night.
Explanation: It’s C because ordering pizza and popcorn will make your diet worse and create even worse habits.
