The false spider mite, Brevipalpus phoenicis, has only two chromosomes. Which of the following pieces of evidence would allow yo
Reptile [31]

Answer:

The correct answer is - a. If these two mite chromosomes have different genes at different loci.

Explanation:

If it is 2n= 2, it means that it is diploid and has two sets of chromosomes in which one set comes from mother and the other from father which means parent's genes contribute to diploid equally. Both sets of chromosomes form homologous chromosome pair. Each homolog of the pair has the same gene at the same loci in diploid and if it has not the same homologous gene at the same loci these are haploid.

What is the name of the period from 2 to 8 weeks following fertilization during which significant growth occurs in the major org
poizon [28]

Answer:

The correct answer is embroynic stage

Explanation:

The prenatal development is divided into three stages germinal stage, embryonic stage and fetal stage. The period of two weeks after fertilization is called the germinal stage. In this stage, the zygote divided and gets implanted in the uterine wall.

The embryonic stage starts for two weeks and lasts up to 8 weeks after fertilization. At this stage, the cell mass is called embryo. In the embryonic stage, the basic brain structure, CNS, PNS are developed. All the basic organs and body parts develop in this stage except sex organs. So the right answer is the embryonic stage.

The effectiveness of two antibiotics administered together may be greater than the effectiveness of either antibiotic used alone
aleksley [76]

Answer:

The correct answer is: enhanced zones of inhibition in the area between two adjacent disks.

Explanation:

  • According to the question, the two antibiotics show the property of Synergism.
  • Synergism can be defined as the property of two drugs, where the efficiency of activity (killing the bacteria) obtained on using the two drugs together is far more than the efficiency obtained by using individual drugs separately.
  • In the disk diffusion method, the efficiency in activity (killing of bacteria) of two drugs is determined by plating a nutrient agar media with the particular target bacteria and adding the two antibiotics in two discs separated from each other by a certain distance.
  • Both the antibiotics diffuse into the agar media from the discs and kill the target bacteria.
  • Zone of inhibition can be defined as the circular clear zone on the nutrient agar plate obtained after allowing the bacteria to grow for the required period of time. This is the region where no bacteria grow as they are killed by the antibiotics used.
  • Depending upon the efficiency of the antibiotic used and also its ability to diffuse into the nutrient agar medium, bacteria tends to grow  near the periphery of the nutrient agar plate where the antibiotic fails to reach.
  • In the question, as the two antibiotics used show synergistic effect, the region on the nutrient agar plate in between the two discs, where both the antibiotics are able to percolate will show a larger zone of inhibition.
