When fruit fly embryos first begin to develop, a large cell is generated that contains over 8000 nuclei that are genetically ide

ntical with one another. What is most likely responsible for this result?
A. The embryo passes through multiple rounds of S phases, but M phases does not occur.
B. This large cell becomes malignant and cancerous.
C. The embryo passes through multiple rounds of the cell cycle, but cytokinesis does not occur during M phases.
D. This large cell remains in the G0 phase for a long time.

Answer:

The embryo passes through multiple rounds of the cell cycle, but cytokinesis does not occur during M phases.

Explanation:

The cell cycle includes a series of events that make new cells from the existing cells. During the process, nuclear division during the M phase produces daughter nuclei. Nuclear division is followed by cytokinesis. Cytokinesis is the division of cytoplasm and results in the formation of daughter cells.

If a cell undergoing cell cycle forms daughter nuclei by mitosis, all the daughter nuclei are genetically identical. In the absence of cytokinesis, cytoplasm would not divide and the daughter nuclei will remain in the parent cell only. Repeated nuclear division without cytokinesis would produce multiple nuclei present in the parent cell.

Even though the idea of recycling materials and using them in other ways seems like a good idea, why is the idea of using recycl
nordsb [41]

Answer:

The idea of using recycle tires at playgrounds is a concern for some scientists because they contain carcinogenic substances.

Explanation:

Recycle tires are in playgrounds as rubber mulch. This one is on the playground's floor to cushion the impact of any falls that kids may have while playing. The problem with this product is that, as they are old tires cut into little pieces, they still have the tires' toxins such as arsenic, benzene, cadmium, mercury, etc. Exposure to these toxins can cause cancer. This is why some scientists are concerned with this material in areas where kids are exposed to it since they are more vulnerable to carcinogens than adults.

dedylja [7]

Answer:

Phenotypic ratio: 1:4:6:4:1

Punnett square: Below in the explanation box

Frequency distribution: In the attached files

Explanation:

<u>Available data</u>:

  • The kernel color in wheat is a continuous trait determined by two additive diallelic genes    
  • The red kernels are determined by two genes and two dominant alleles (R1R1R2R2)
  • The white kernels are determined by two recessive alleles at the same two genes (r1r1r2r2)
  • R1 and R2 alleles are dominant over r1 and r2, respectively
