Answer:
D, C and A are the correct options.
B is less likely rather is a personal reference.
Accuracy describes how well a measuring instrument determines the variable it is measuring. How close the value is to real value. The level of accuracy of measuring tool determines the detail to which it can measure. In order to be accurate in their work scientists need first select a measuring instrument that allows an appropriate measure of accuracy and then to calibrate it. Calibrating an instrument involves measuring already known quantities to check how accurately it is. In the laboratory accuracy of a test is determined when possible comparing results from the test in question with results geenrated from an established reference method.

Reproductive cells are haploid (have 1/2 the chromosomes), whereas somatic/body cells are diploid (have the full set of chromosomes)
This makes sense if you think about it. Using the example from the question, every dog has 78 chromosomes. This includes two of each (there are two chromosome 1's, two chromosome 2's, etc. This is visible in the karyotype attached). One set of these chromosomes were inherited from the mother, and one set from the father. Each parent contributed 39 chromosomes (one chromosome 1, one chromosome 2, etc.). If the dog in the question were to have 78 chromosomes in its sperm cells, it would contribute two sets to its offspring. When combined with the chromosomes in the egg cell, the offspring would end up with extra chromosomes. Therefore, both the sperm and the egg cells will have 39 chromosomes, one of each. When combined, they will produce offspring with 78 chromosomes, the proper number.
The answer for this question would be A. Line A
The answer for the given question above is the second option. The statement that best describes a typical difference that could be found between the "Analysis" and "Conclusion" section of the lab report is this: Only the "Analysis" section includes specific data comparisons, and the only "Conclusion" section suggests further research. Hope this helps.
