Answer:
Hershey Chase and Griffith experiment supported the same conclusion which was: DNA is the molecular substance of genetic inheritance.
Explanation:
Both experiments have was based on different phenomenon and techniques to prove same conclusion.
Hershey and chase conducted an experiment via bacteriophage which consists to DNA and protein coat that infects bacterial cells. He proved the DNA as genetic material by the help of transduction mechanism (Incorporation of Bacteriophage DNA in to bacterial cells). He used two group of Bacteriophage 1st group of Phage contain radioactively labelled proteins by Sulphur 32 isotope. While 2nd group contain Bacteriophage having P32 labelled DNA to infect Bacterial cells. After the infection, the Reaction tubes subjected to centrifuge and presence of radioactivity was determined in pellet and supernatant. The 1st group show radioactivity in supernatant while 2nd group shows racdioactivity in pellet or bacterial cells.
Griffiths just hypothesized a substance that can be transmitted from dead organism to alive organisms with the help of transformation phenomenon (uptake of Genetic material from the surrounding or environment). He conducted his experiments on <em>Streptococcus pneumonia avirulent and virulent species. </em>By mixing dead virulent species and live avirulent species and injecting into the mice results in the death of an experimental animal. While alone dead virulent species and live avirulent species fail to cause disease in mice.
Answer:
The generally accepted parts of modern cell theory include: All known living things are made up of one or more cells. All living cells arise from pre-existing cells by division. The cell is the fundamental unit of structure and function in all living organisms.
Answer: Concentration gradient (happy to help)
Explanation: The particles may move along or against their concentration gradient.
We all have two alleles, or versions, of each gene. Being hom0zygous for a particular gene means you inherited two identical versions. It's the opposite of a heterozygous genotype, where the alleles are different. People who have recessive traits, like blue eyes or red hair, are always hom0zygous for that gene.

Answer:
Rephrasing text material in your own words is an effective way to promote <u><em>deep processing.</em></u>
Explanation:
Deep processing can be described as a method of processing by the analysis of the language being used. Deep processing can easily be described as a way in which a word can be more easily remembered by associating with anything else that a person can remember. For example, using images or other easier words to remember a difficult word.
Rephrasing a text material is an effective deep processing method to remember a text.
