C. The quote appears at the beginning of the paragraph.
Answer:
Turbidity
Explanation:
The variable that is the best to help a student to measure in order to know the impact of soil erosion which was caused by the construction project that took place on the river TURBIDITY will be the best variable reason been that TURBIDITY help to measure the cloudiness in a water which means that the higher the cloudiness in a water the higher the TURBIDITY and Secondly a situation where their is a high soil erosion it will often lead to reduction in clarity of water which is why TURBIDITY is a vital tool to help measure all the particles in water which a physical eyes cannot see.
According to the history and physical examination of the patient, the patient may have a upper gastrointestinal bleed most probably from a bleeding peptic ulcer. A bleeding peptic ulcer can cause abdominal pain and vomiting described as coffee ground vomit because of the reaction of the blood with the stomach acids. The patient's vital signs signify that the patient is in the state of hypovolemic shock. The emergency medicine consultant should use an oxygen mask with caution because additional vomiting episodes may recur and if the patient is wearing an oxygen mask, the vomit cannot be cleared thoroughly and may even cause aspiration.
Answer: A. 20
Explanation:
Radiation dose = 160 cG, or
Radiation dose = 160 x 10-2 G
Radiation dose = 1.6 G
The relative biological effectiveness (RBE) on neutron irradiation is then calculated with the formula:
RBE of Co-60 = inactivation constant x dose x neutron irradiation
getting:
Co-60 RBE = 3,125 x 1.6 x 4
Outcome:
RBE of Co-60 = 20
which shows that option A is correct
