The correct option is this: THE MASS OF THE PROBE REMAINS THE SAME, BUT THE WEIGHT OF THE PROBE DECREASES.
The mass of an object is a measure of the amount of substance it contains and this amount always remain the same unless there is a change in quantity of matter. This is the reason why the mass of a substance will remain constant, no matter where it is placed, whether on planet earth or on another planet. The weight of a substance on the other hand is a force, whose value depends on the force of gravity. Thus, the force of gravity that exist in the place, where the object is placed will determine its weight.
Sporadic cancer is cancer by chance, there is no relative with the same type of cancer. Familial Cancer, on the other hand, is a combination of genetic and environmental factors. Hereditary cancer, moreover, happens when a defective gene is passed from parent to child. Breast and ovarian cancer fall under hereditary cancer though it does not mean that if either of the parents have these types of cancer, the offspring will definitely acquire it. If either of the parents has the defective gene for breast or ovarian cancer, the offspring has higher chances of having the aforementioned cancer.
The patient would have to keep the affected area clean in order to prevent infection.
Replace bandages to aid in keeping bacteria out of affected area.
Answer: D.finding fossils in the same area that are in layers closer to the surface.
Relative dating refers to the age estimation method in which past events are determined, to compare the age of object, organism, strata or rock with the age of other similar entity. This method gives an approximate or estimated age, it does not provide absolute age.
The older fossils are found in deeper layers of the strata as compared to younger fossils. This represents the geological time and life span of primitive or preexisting organisms. Therefore, according to the given situation, finding fossils in the same area that are in layers closer to the surface is the best conclusion.
