Answer:
renewable resources
Explanation:
Resources are substances that are used to produce energy.
They can either be renewable or non renewable.
Renewable resource can be defined as the resources which have long availability or faster replenishment as compared to the consumption rate of the resource or both.
Examples include air, soil, plants, animals and others.
Alternatively, non renewable resource refers to the resources which are available for a limited amount of time or whose replenishment is slower as compared to its consumption rate or both.
Examples include fossil fuels like coal, mineral resources.
Crops, as mentioned earlier, are a renewable resource.
Crops can be grown again and again. Also, crops are renewable as long as the soil is available for its growth. Appropriate soil provides ideal platform for growth of different types of plants.
Soil along with weather conditions like rain, are renewable resources. They will be available as long as the planet Earth exists. This makes replenishment of plants easier.
Also, crop harvesting is a continuous process. Once the harvested crop is sold, another harvest of the crops is begun. Hence, this makes the crops available due to faster replenishment.
Hence, crops, along with soil and rain, are a renewable resource as long as it can be grown again and as long as the soil is available. Also, ideal conditions which favour crops will be available till the planet Earth exists.
Fossil fuels are non renewable resources since they are available for a finite period of time.
Mineral resources are non renewable resource since they are available for a finite period of time.
Both fossil fuels and mineral resources will perish once they are consumed completely and their replenishment takes a long period of time. Hence, the unavailability of both fossil fuels and mineral resources will be as long as the replenishment takes place.
immunization
viral detection
antibiotic
Answer:
The correct answer would be immunisation.
Immunisation refers to the process of developing immunity against a particular pathogen or disease.
In this process, a vaccine consists of attenuated or heat killed pathogen is administered into a person.
The body produces a primary immune response against the weakened pathogen or antigen. It also develops memory of the pathogen due to which body is able to recognise the pathogen easily if it encounters the same in near future.
It helps the immune system to produce quicker and amplified immune response against the pathogen and our body becomes immune to that particular disease or pathogen.
Thus, immunisation is required before travelling to Africa as yellow fever is very common there.
The most viral function of Earth's magnetic field is to protect our planet from the harmful effects of solar and cosmic radiation.

Answer: 2
Explanation:
MA = Fo/Fi
Where MA= mechanical advantage
Fo= Output force
Fi = input force.
Fi= 500 N
Macromolecules are large molecules with many atoms. They have various functions in the body including storage and transmission of hereditary information through nucleic acids. Thus, option D is correct.
Nucleic acids are one of the major macromolecules that are made of nucleotides joined together to make a whole chain. The nucleic acids are present in the nucleus of the cell and are crucial as they are involved in the transfer of hereditary characters.
The nucleic acids include DNA and RNA that are majorly involved in coding, storing, and transferring genetic information from generations. DNA comprises the genetic material and RNA allows the regulation and coding of the genes.
Therefore, option D. the nucleic acids store and transmit hereditary information is correct.
