The anti-viral protein is known as:
Viral proteins are proteins generated by a virus. As viruses hijack much of their host's cellular machinery to support their life cycle, they encode very few of their own genes; viral proteins are therefore generally structural components, for the viral envelope and capsid.
Non-structural proteins and regulatory or accessory proteins can also be viral proteins. Antiviral proteins are proteins that are induced by human or animal cells to interfere with viral replication.
These proteins are isolated to inhibit the virus from replicating in a host's cells and stop it from spreading to other cells.
What is the other name of rabbis?
Rabies is a viral disease that is spread through the animal bite such as the dog. It is caused by the infection of rabies virus.
The infection caused from this leads to encephalomyelitis i.e the inflammation of the brain as well as the spinal cord.
The transmission of the virus happens through the saliva and affects the CNS or Central nervous system. This virus belongs to the family called Rhabdoviridae.
Children are vaccinated against polio because
Which of the following is a mismatch?
AIDS or Acquired Immune Deficiency Syndrome is a syndrome caused by the HIV virus.
In this condition, a person’s immune system becomes too weak to fight off any kind of infection or disease. AIDS is usually the last stage of HIV infection; a stage where the body can no longer defend itself and thus spawns various diseases.
Which bacteria is responsible for causing typhoid?
Salmonella typhi is the bacterium responsible for this disease and humans are the only carriers.
The first case of typhoid fever was reported in the United States in the early 1900’s. Overall, about 21 million people are infected with this disease annually, and about 200,000 cases are fatal.
The disease which are present since birth and are due to some genetic disorder is called:
Congenital refers to a condition or disease which is present at birth. The condition can be inherited (genetic) or caused by environmental factors. Some maternal infections, such as HIV, can be passed onto the child and cause a congenital condition.
Diarrhea, cholera, typhoid are the diseases that have one thing in common that is

Arrange the following components in decreasing order according to their percentage present in air.
The term "water-pollution" can be defined in several ways. Which of the following statements does not give the correct definition?
A change in pressure of the water bodies
Which one of the following is not a cause of ozone depletion?
The nitrogen molecules present in air can be converted into nitrates and nitrites by:
Nitrogen fixation is the essential biological process and the initial stage of the nitrogen cycle. In this process, nitrogen in the atmosphere is converted into ammonia (another form of nitrogen) by certain bacterial species like Rhizobium, Azotobacter, etc. and by other natural phenomena.
Plants are the main source of food. The nutrients obtained from plants are synthesized by plants using various elements which they obtain from the atmosphere as well as from the soil.
This group of elements includes nitrogen as well. Plants obtain nitrogen from the soil through the process of protein synthesis. Unlike carbon dioxide and oxygen, atmospheric nitrogen cannot be obtained through the stomata of leaves.
Because the concentration of nitrogen gas present in the atmosphere can not be directly used by plants and also the concentration of the usable form of nitrogen in the atmosphere is very less. There are certain bacteria and some natural phenomena which help in Nitrogen fixation.
The water cycle in nature involves which of the following processes sequentially?
The water cycle in nature involves : Evaporation, condensation and precipitation.
Select the incorrect statement regarding the rainfall with low pH.
Match column I with column II and select the correct option from the given codes.
(a) Particulate matter
(e) Vegetable peel
(i) Chemical water pollutant
(ii) Non-degradable soil pollutant

Which one among the following is not a layer of atmosphere?
These layers are:
Few characteristics of a type of soil are given below. Find the type of the soil based on the given characteristics.
1. Presence of iron oxides in the soil.
2. Formed by the erosion of rocks in areas of high temperature.
3. Soil appears red in colour.
4. Found in western and eastern ghats.
5. Soil is not very fertile.
These are the characteristics of laterite soil.
What would happen, if all the oxygen present in the environment is converted to ozone?
Ozone is a poisonous gas and is thus only present in a thin layer in the stratosphere. lf all the oxygen is converted to ozone, the environment will become poisonous and kill all living forms. Ozone is O3, in its elemental form or even in its combined form it is highly toxic.
Ozone can damage lungs and even low amounts of ozone can cause chest pain, coughing, shortness of breath and lung irritation.However at the stratospheric level, no life form exists and there ozone prevents us from the harmful U.V radiations of the sun.
Which of the following are the three primary nutrients needed for plant growth?
Which of the following is a food-fodder mixed farming system?
(i).The use of a single farm for multiple purposes, as the growing of cash crops or the raising of livestock is called mixed farming.
(ii) Farming involving both the growing of crops and the keeping of livestock is called mixed farming.
(iii) A type of commercial agriculture concerned with the production of both crops and animals on one farm. Stock on a mixed farm used to be grazed on fallow land, but many modern mixed farms produce some, or all, of their fodder crops.
Why is organic manure considered better than fertilisers?
Which of the following refers to inland fisheries?
Inland fisheries are any activity conducted to extract fish and other aquatic organisms from "inland waters". The term "inland waters" is used to refer to lakes, rivers, brooks, streams, ponds, inland canals, dams, and other land-locked (usually freshwater) waters (such as the Caspian Sea, Aral Sea, etc.).
Which of the following is an important objective of biotechnology in the field of agriculture?
Biotechnology is being used to address problems in all areas of agricultural production and processing. This includes plant breeding to raise and stabilize yields; to improve resistance to pests, diseases and abiotic stresses such as drought and cold; and to enhance the nutritional content of foods.
Biotechnology is being used to develop low-cost, disease-free planting materials for crops.
