Match the diseases in Column I with the site of infectious in Column II :
Column I Column II (a) Dengue 1. Intestine, Brain (b) Polio myelitis 2. Skin and Blood (c) Measels 3. Respiratory tract and Nervous system (d) Chicken Pox 4. Skin and Respiratory tract
This question requires matching specific infectious diseases listed in Column I with their corresponding primary sites of infection or major affected systems listed in Column II.
Matching Diseases with Infectious Sites
Let's analyze each disease and its typical infectious site:
Dengue: Infectious Sites
Dengue is a viral infection transmitted by mosquitoes. The virus primarily targets cells within the blood and immune system. Symptoms often include skin rashes, reflecting involvement of the skin, and systemic effects related to the blood and circulatory system.
Therefore, Dengue matches with: 2. Skin and Blood
Polio Myelitis: Infectious Sites
Polio myelitis, commonly known as polio, is caused by the poliovirus. The virus typically enters the body through the mouth, infecting the intestine. From the intestine, it can spread to the central nervous system, specifically affecting the nerve cells in the spinal cord and brain, which can lead to paralysis.
Therefore, Polio myelitis matches with: 1. Intestine, Brain
Measles: Infectious Sites
Measles is a highly contagious viral illness. It initially affects the respiratory tract (nose, throat, lungs) causing symptoms like cough and fever. The virus then enters the bloodstream and spreads throughout the body, often causing a characteristic skin rash. In some cases, it can also lead to complications affecting the nervous system.
Therefore, Measles matches with: 3. Respiratory tract and Nervous system
Chicken Pox: Infectious Sites
Chicken Pox is caused by the varicella-zoster virus. It is typically acquired through the respiratory tract. After initial infection, the virus spreads through the bloodstream to the skin, where it causes the characteristic itchy, blistering rash. Thus, both the skin and respiratory tract are key sites.
Therefore, Chicken Pox matches with: 4. Skin and Respiratory tract
Summary of Matches
Here is a summary of the correct matches:
| Column I (Disease) | Column II (Infectious Site) |
|---|---|
| (a) Dengue | 2. Skin and Blood |
| (b) Polio myelitis | 1. Intestine, Brain |
| (c) Measles | 3. Respiratory tract and Nervous system |
| (d) Chicken Pox | 4. Skin and Respiratory tract |
Important Questions from Miscellaneous
A stone is thrown horizontally from the top of a 20 m high building with a speed of 12 m/s. It hits the ground at a distance R from the building. Taking g = 10 m/s2 and neglecting air resistance will give :
A sphere of volume V is made of a material with lower density than water. While on Earth, it floats on water with its volume f1V (f1 < 1) submerged. On the other hand, on a spaceship accelerating with acceleration a < g (g is the acceleration due to gravity on Earth) in outer space, its submerged volume in water is f2V. Then:
A railway wagon (open at the top) of mass M1 is moving with speed v1 along a straight track. As a result of rain, after some time it gets partially filled with water so that the mass of the wagon becomes M2 and speed becomes v2. Taking the rain to be falling vertically and the water stationery inside the wagon, the relation between the two speeds v1 and v2 is :
Consider the following statements:
1. Distance between the longitudes becomes zero on North Pole and South Pole.
2. Distance between the longitudes is maximum on the Equator.
3. Number of longitudes is more than number of latitudes.
Which of the statements given above is/are correct?
One block of 2⋅0 kg mass is placed on top of another block of 3⋅0 kg mass. The coefficient of static friction between the two blocks is 0⋅2. The bottom block is pulled with a horizontal force F such that both the blocks move together without slipping. Taking acceleration due to gravity as 10 m/s2, the maximum value of the frictional force is :
