The Hershey and Chase experiments showed that the inherited genetic material was DNA (deoxyribonucleic acids). In this experiment, the scientists labelled the DNA molecule with a radioactive isotope of phosphorus.
Centrifugation causes the separation of different components according to their size. So, by blending, they centrifugated the mixture of virus and the bacteria, which separated the viral protein capsule and the bacteria. Later, they found that the virus infected bacteria contains the DNA of bacteria, not the protein.
Hence, bacterial cultures infected with a virus were agitated in a kitchen blender to separate the protein coat of virus from the bacteria.
The attraction is maximum between b and c. while the force between a and d is minimum
Answer:
Genotype - RR - 25%, Rr - 50%, rr - 25% (1:2:1)
Phenotype - Round seeds - 75%, Wrinkled seeds - 25% (3:1)
Explanation:
Let the letter "r" stand for the alleles, where R is round seeds and r is wrinkled seeds. A genotype is an individual's genes represented through alleles. Phenotypes are how the genes express themselves. In other words, genotypes will be written using letters, the alleles, and phenotypes will be the possible outcomes of the alleles.
To find the ratios/percentages of the genotypes and phenotypes you can use a punnet squares. Both of the parent seeds have the genotypes Rr and the phenotype of round seeds.
If you create punnet square (which had four boxes in total) 1 will have RR, 2 will have Rr, and 1 will have rr. These are the ratios for the genotypes. Each box represents 25%, so the percentages will be 25, 50, and 25. Finally, 3 of these boxes (RR and Rr) will result in round seeds because those are domiant. Only the genotype rr will result in wrinkled phenotype. Therefore, the ratio is 3:1 or 75% to 25%.
it will be person d, as bikes are made of metal, tents have metal poles, and if person a is in a meadow, they are the tallest structure. a house will act as a shield and absorb the electricity, heat, and energy produced by the lightning.
<h2>Answer with Explanation </h2>
Cellular respiration is a process in which chemical reactions occurs that allows the body to take glucose and transform it into ATP. ATP is a more readily available form of energy for the body than glucose. Cells need energy to perform tasks, and respire to break the chemical bonds in ATP and then use it for energy. So, respiration occurs at all times in the human body, and is essential for survival.
