Answer:
Explanation: When this study was carried out by Meselson and Stahl, their findings are compatible with the trend expected by semi-conservative analysis, establishing this as the right template. The two parent strands are split as DNA replicates, and each strand acts as a blueprint for a new DNA strand synthesis.
After the first replication, there are two DNA double helices each marked as superscript 14 N slash superscript 15 N. After the second replication, four double helices of DNA are produced. Three of them are marked as 14 N superscript slash 15 N. Two other DNA was marked as 14 N slash superscript 14 N.
Remember that after a round of testing, Meselson and Stahl were able to rule out the moderate template based on the results. At that point, though, they were unable to rule out the dispersive model because that model predicts the same trend as the semiconservative model. But after two trials, the findings made it possible for them to rule out the dispersive design.
Answer:
the trait with Mendelian inheritance shows segregation in the F2 generation.
Explanation:
Blending inheritance is the theory that the offspring inherits any characteristic that are intermediate between those of the parents.
However, Gregor Johann Mendel showed that this not true that hereditary substances from parents merge together in their offspring.
In the given question,
the offspring of true-breeding parents show an intermediate phenotype, although a trait such as flower color in snapdragons is determined by two alleles with incomplete dominance.
The difference is that the trait with Mendelian inheritance shows segregation in the F2 generation.
The answer is C
Parasitism is the relationship between two animals, one is benefiting and the other is harmed. In this example, the tapeworm is benefiting by eating all the pig’s food, but the pig is harmed.
I hope this helped!!
Living things produce offspring of the same species, but in many cases offspring are not identical with each other or with their parents. Plants and animals, including humans, resemble their parents in many features because information is passed from one generation to the next.
