<h2>Given statement is false</h2>
Explanation:
According to dispersive model of DNA replication,DNA molecules are hybrids of parental and daughter DNA;In this model each individual strand is a combination of original and new DNA
Meselson and Stahl did an experiment on DNA replication using E.coli bacteria
- E.coli was grown in a medium containing heavy isotope of nitrogen,bacteria took up the nitrogen and used to synthesize new biological molecules,including DNA
- It was grown for many generations,the nitrogenous bases of the bacteria's DNA were all labelled with heavy nitrogen
- Bacteria were then switched to light nitrogen isotope and allowed to grow for several generations
- They then measured the density of the DNA using density gradient centrifugation
- This method separates molecules such as DNA into bands by spinning them at high speeds in the presence of another molecule, such as cesium chloride
- Each DNA produced two DNA molecules each with one new strand and one old strand called semi conservative replication(half of the parental DNA conserved in daughter DNA)
- Each DNA strand act as a template for synthesis of new strand
- Hence,dispersive model of DNA was eliminated and semi-conservative model of DNA replication was proved by the above experiment
Answer:
The “recommended temperature limit” indicates limit of the temperature that is good for our world.
Explanation:
The temperature related to the “recommended temperature limit” means that in the graph there is a limit of temperature for our world's environment. if the temperature is between this limit, there is less or no adverse effect on our environment while on the hand, if the temperature exceeds from this limit, then it adversely affected our world because the concentration of carbondioxide gas in the atmosphere increases due to this increase temperature..
Eukaryotic cells<span> contain membrane-bound organelles, including a nucleus</span>.Prokaryotic cells<span> do not contain a nucleus or any other membrane-bound organelle.</span>
Answer: Don’t listen to the other person, B is incorrect. A is the correct answer.
Explanation: The law of conservation of energy states that energy cannot be created nor destroyed. B says that the mechanical energy disappears, but this is wrong. It changes into another energy, but the energy doesn’t disappear.
The drawing of a cat is an example of a 3-D drawing as applied in biology.
<h3>What is 3-D drawing?</h3>
A 3-D drawing is such the height, depth and the width of the object ios shown. Three dimemsional drawings are common in architechture as well as in biology.
Hence, the drawing of a cat is an example of a 3-D drawing as applied in biology.
