A radiologist performs multiple tests including radiography (X-rays), MRI, CT scans, and ultrasounds to diagnose and treat various diseases and injuries.
A radiologist is a medical doctor specialized in diagnosing and treating diseases and injuries using medical imaging procedures. One of the key tests performed by a radiologist is a radiography, also known as X-ray. In this test, a small amount of radiation is used to produce images of the inside of the body. They also perform other tests such as Magnetic Resonance Imaging (MRI), Computed Tomography (CT) scans, and ultrasounds, depending on the nature of the patient's condition.

B altered water flow
C deforestation of woodlands
D decreased water quality
Answer:
Option (C)
Explanation:
In order to set up urbanization in a selected area, initially, a large number of trees are being cut down. This process is commonly known as deforestation.
The deforestation process has various impacts on the environment and the climatic condition at various places. Extensive cutting down of trees leads to the occurrence of rapid soil erosion, where the materials from the topsoil are entirely carried away by wind and water. Due to this, there occurs a high absorption of incoming solar energy that increases the temperature of that area.
In addition to this, trees are the main source from which the oxygen is provided. The absence of trees also leads to an increase in the amount of carbon dioxide because the carbon dioxide will not be absorbed by the trees and in return, it won't be able to provide us oxygen. Due to this, the amount of carbon dioxide also increases.
Thus, the above changes are caused due to the deforestation of woodlands.
Hence, the correct answer is option (C).
Explanation:
deforestation of woodland
Light takes 162.1 seconds to travel from Venus to earth.
Explanation:
Speed of light=3 x 10⁸ m/s
distance between Venus and earth =30,220,000 miles=48634375680 m
Now the distance is given by d= v t
d= distance
v= velocity
t= time
48634375680= 3 x 10⁸ t
t=162.1 s
