Answer:
Control comes with regulating the amount of radiation that a patient is exposed to (using a dosimeter) while accomplishing the task required – such as taking radiology images or irradiating tumor cells. Regulating radiation levels include ensuring the right distance between the patient and radiation source and implementing requisite shielding techniques. The time duration for exposre should be short and radiation sources should also be labeled accordingly.
Answer: C. cropping patterns
Explanation:
Cropping pattern can be defined as the area in which the different crops grow at different times of the year. It also consider the spatial arrangement and time used to grow a sequence of crops that are grown in a particular area of land.
The given situation is indicative of the cropping patterns as different crops are grown in the same land over particular period of the year.
Charles Darwin noticed that among the same species there were variations in traits based upon geographical location. These changes may have evolved from climate differences, predator/prey relationships and food sources. This particular experiment was intended to duplicate natural selection by demonstrating the concepts with artificial selection. The result was that over time, new traits could be bred for. Although there may be more than one correct answer here, the best answer is the first; desirable traits can be selected and bred in offspring.
The correct answer that would best fit the given statement above would be the third option. <span>In a genome-wide expression study using a DNA microarray assay, each well is used to detect the expression of a specific gene by a cell. Hope this answers your question. Have a great day!</span>
Table 1: The horizontal pulling forces (F) and resulting acceleration (a) for the cart.
The cart experiences no motion when there is 0.1 N of horizontal force, so F=0 in this case. When one uses Newton's Second Law to find the acceleration caused by each force, it becomes clear that every row in the chart represents a horizontal force of approximately F=20 N. The best fit for the missing value is F=-30N.
