Although the options are not provided, the answer is, they think he is a bit peculiar, but they revere him.
The neighbors are seen to be cautious of Oliver, keeping him distant and not becoming too acquainted with him. The fact that they do not call him by his first name reflects this. However, they also feel he has "something strange and proud and glorious lost in [him]". This part indicates that the neighbors indeed revere Oliver.

Microorganisms placed in high concentrations of salts and sugars undergo lysis.
gayaneshka [121]
The statement is true. Because of the hypertonic environment, the water will simply diffuse out of the microorganisms as the solute concentration is higher outside the cell. This will lead to plasmolysis of the cell and eventually cell death.

If a person is heterozygous for the Δ32 allele of the CCR5 gene, how many of the four daughter cells produced by meiosis will ha
never [62]

Answer:

The correct option is B: 2

Explanation:

Before meiosis takes place, the entire genetic material within the cell is replicated, this results in 2 copies of the 2n DNA. Since the person is heterozygous for the mutated allele, there is one copy of it present within one 2n set of chromosomes. Two of the 2n chromosomal sets means there would be two copies of it present in total and when the segregation event happens to create haploid cells, two of the cells will inherit the mutated copy.

Hope that answers the question, have a great day!

The data obtained from the meselson–stahl experiment after one generation of replication eliminated the dispersive model of dna
Sedaia [141]
<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
