There are many conditions essential for being disease free. The two most important being:
(a) Eating nutritious and balanced diet:
Nutritious and balanced diet will keep our body in perfect order and as such will help in the proper coordination and functioning of the body.
(b) Personal and community health issues:
Health implies state of physical, mental and social well-being. It depends on the surrounding we live in and as such living in a clean environment can have a positive impact on our life

(a) (i) Self pollination ? When the pollen grains from the anther of a flower are transferred to the stigma of the same flower (or another flower on the same plant), it is called self pollination. 

(ii) When the pollen grains from the anther of a flower on one plant are transferred to the stigma of a flower on another similar plant, it is called cross pollination. 

(b) When an insect sits on the flower of a plant for sucking nectar, then the pollen grains from the anther of this flower sticks to its body. And when this insect sits on another flower of another similar plant, then the pollen grains sticking to its body are transferred to the stigma of this second flower. In this way, the insect transfers the pollen grains from the anther of flower in one plant to the stigma of flower in another plant and causes cross pollination.

(c) 

Self Pollination: It is the transfer of pollen grains from the anther of a flower to the stigma of the same or another flower on the same plant. 

Cross Pollination: It is the transfer of the pollen grains from the anther of a flower to the stigma of another flower on a different plant of the same species.

(i) The reproductive process which involves two parents is called sexual reproduction. In this process, both the male and the female genders are required for producing the new generation. 

(ii) Asexual reproduction in the process of reproduction, where only one parent is involved. This means that an individual organism is capable of generating new generation.

One word for each given phrase is as follows: 

(i) HIV-AIDS 

(ii) Vas deferens 

(iii) Parturition 

(iv) Sexually transmitted protozoan disease.

To feed on mosquito larvae so as to eliminate the vectors responsible for causing malaria.

Gambusia is a kind of fish that preys upon the larvae of mosquitoes. It is therefore introduced into the drains and ponds. To feed on Mosquito larvae / to eliminate the vectors responsible for causing malaria. It thus helps in controlling malaria.

(d) All of these

Three laws associated with the answerability of the government are :

• Right to Information Act 
• Right to be Heard Act 2012 
• Rajasthan Public Service Commission Guarantee Act, 2011.

The conditions essential for being free of diseases

(i) Taking good food (balanced diet)

(ii) Maintaining personal and public hygiene.

The health of all organisms will depend on their surroundings or their environment. The environment includes the physical environment. Our social environment, public cleanliness, good economic conditions and jobs, social equality and harmony are also important for individual‘s health.

The transfer of pollen grains, in flowering plants, from one flower to another, is called cross-pollination. The agencies which carry out cross-pollination are wind, water and animals.

Cross-pollination is superior to self-pollination in ways mentioned below,

• It brings about genetic recombination and production of new varieties. 

• Cross-pollination results in healthy and stronger offspring. 

• Variations are caused due to this. 

• It leads to the production of seed in self-sterile plants

1. Public cleanliness

2. Good quality of food and water are two conditions which are essential for good health.

Good health of a person depends on

(i) social environment.

(ii) public cleanliness.

(iii) good economic conditions and earnings.

(iv) social equality and harmony.

Two major processes namely formation of gametes and fusion of gametes constitute sexual reproduction

Significance-(i) Incorporates the process of combining DNA from different individuals during reproduction.

(ii) Increase genetic variation.

(iii) Promotes diversity in the offsprings.

(iv) Play a role in the origin of new species.

(a) A sexual reproduction results in new combination of characters and increases genetic variations. 

(b) It promotes diversity of characters in the offspring. 

(c) It speeds up the process of making variations in the population.

(i) It is necessary for seed formation and thus, perpetuation of species.

(ii) It stimulates the development of fruits.

(iii) Cross-pollination brings about genetic recombination.

Reproduction is the phenomenon which involves the production of an offspring by particular individual or individuals to propagate their species. Reproduction is done during reproductive phase.

Types of reproduction

Reproduction can be of two different types, namely, asexual reproduction and sexual reproduction.

• Asexual mode of reproduction: It is a mode of reproduction in which a single individual is responsible for creating a new generation of species.

• Sexual mode of reproduction: It is a mode of reproduction in which two individuals are responsible for creating a new generation of species.

Reproduction in unicellular organisms is different from that of the reproduction in multicellular organisms. Most often unicellular organisms reproduce asexually. Some of them can also exhibit sexual mode of reproduction. Unicellular organisms reproduce asexually through fission, fragmentation, regeneration, budding, vegetative propagation and spore formation.

(i) Spore formation in Rhizopus.

(ii) The thick walls protect the spores until they come in contact with soil.

(iii) The thread-like projections are called hyphae.

Under the Rajiv Gandhi National Fellowship Scheme, our school is giving scholarships for higher education for SC students and Pre-Metric Scholarship Scheme and Post Metric Scholarship Scheme for ST students and Specialized scholarship schemes are being run for special merit holders.

When we are sick, we have a weakness. If we consume hard food, it is difficult to digest it. Hence we should consume bland food. Nourishing food is also essential as they provide nutrients for us. Therefore we should take bland and nourishing food when we are sick.

Three reasons why we would think that wear sick and ought to see a doctor are:

1. There is a chance of getting sick due to microbial activity.

2. Due to deficiency of vitamins, minerals (nutrients) we get diseases.

3. Due to genetic difference also we get diseases.

The answer is (d) continue the species generation after generation

Reproduction is essential to the lineage of the species whereas other life processes are essential to keep the organism alive.

The consistency of DNA copying during reproduction is important for the maintenance of body design features that allow the organism to use that particular niche. Reproduction is therefore linked to the stability of populations of species.

Variations are beneficial to the species than individual because sometime for a species, the environmental conditions change so drastically that their survival becomes difficult. For example, if the temperature of water increases suddenly then most of the bacteria living in that water would die. Only few variants resistant to heat would survive and grow further. However, if these variants were not there then the entire species of bacteria would have been destroyed. Variation is the useful for the survival of species over time.

Body design/ morphology of an organism defines the way how much he is fitted or suitable for a specific habitat. E.g.- a bacteria doesn’t need big houses or area to survive and also it's nutritional requirements are very less but humans, on the other hand, need much larger space and have complex nutrition system. A fish can survive under water because of gills but a bird or human cannot.

Binary fission in amoeba: A single cell divides itself into two daughter cell is known as binary fission, binary fission can also occur in particular axis. e.g., Amoeba.

Multiple fission in Plasmodium: It is also a mode of asexual reproduction in which a cell divides itself into many daughter cells simultaneously. It occurs in definite orientation. e.g., yeast, malarial parasites.

(i) (a) Binary fission-Amoeba

(b) Binary fission: Two daughter cells.

Multiple fission: Many daughter cells simultaneously

(c) Asexual reproduction, the involvement of a single parent.

The functions of petals are to attract insects for pollination and to protect the reproductive organs, which are at the center of the flower.

Government has opened Employment Training Centers in all the areas of Rajasthan State where young people are trained to set up and run various industries through skill development. Loans are also provided for the youth who get training from here. In addition, many famous industrial establishments also work for skill development in youth and also give jobs to the youth after giving them training. Employment camps are also being set up in various districts from time to time by the government in which guidance and information regarding employment and training is provided to all the youth.

Rajasthan governments ‘Chief Minister’s Free Medicines and Check-up Scheme’ all government hospitals provide free medicines delivery for patients in all the cities, villages and towns and most of the medical check ups are also made free. Free medicines are provided to the animals too.

The Rajasthan government has started the toll-free 104 telephone number service by which anyone can consult specialist doctors for health solutions, and for mother and baby free ambulance service is also provided. The patients can get a free ambulance service at number 108. Mother and Child Protection Scheme is being run to provide health services to mothers and infant (child).

In these three cases, if we get jaundice is most unpleasant. Because jaundice virus is present in liver cells. Liver is the largest and important organ of our body. If it is damaged, leads to more danger to our body.

Lice and acne will not cause long lasting effects on our body. But in case of jaundice, there will be severe long lasting effects. For example:

(i) High temperature, headache and joint pains.

(ii) Feeling of nausea and vomiting.

(iii) Initiating rashes.

The patient will suffer from poor health and will recover by taking complete bed rest for sometime.

Variation is defined as the slight difference in two organisms or species which distinguishes one from the other. Individual with variation has higher chances of survival since they are better adapted to the environment. Thus, for survival of the fittest and to continue life on earth, variation is an important phenomenon.

The chromosomes in the nucleus of a cell contain information for inheritance of features from parents to next generation in the form of DNA (Deoxyribo Nucleic Acid) molecules. The DNA in the cell nucleus is the information source for making proteins. Hence DNA copying is important in reproduction.

Amoeba reproduces through simple binary fission. Leishmania reproduces asexually through binary fission that occurs along a definite orientation related to the whip-like structure at one end of the cell.

In Amoeba, splitting of two cells during division can take place in any plane.

In Leishmania, binary fission occurs in a definite orientation in relation to the whip like structure.

The Rajasthan government is determined that in the future, no family of the state should remain homeless. Therefore, the Rajasthan government has started the Chief Minister’s Housing Scheme and the Indira Awas Yojana. Under this scheme, grants are being provided to homeless of selected rural households for free land and housing construction. In the urban areas, housing for the poor families is being made available at the low cost under the Chief Minister’s Public Housing Scheme.

Yes, all the people can access this. The people are avail of this.

1. If in the case of Jaundice, the suffering will be more and it will be cured only by taking medicines. Prescribed by a doctor. 

2. Because this is the disease for liver, the normal functioning of the liver will be stopped, and feels unpleasant.

True

All diseases have a immediate cause and a contributory cause. In the case of a baby suffering from loose motion we can infer that it is due to a virus or a bacteria (immediate cause) and the contributory cause in this case is the lack of proper nutritious food, impure drinking water. Thus, in this case there is more than one contributory cause.

There are two level of cause of the disease. They are immediate cause and contributory cause. For example, in the case of a baby suffering from loose motion we can infer that it is due to a virus or a bacteria (immediate cause) and the contributory cause in this case is the lack of proper nutritious food.

The peels of fruits and vegetables and other waste materials which decay and turns good manure can deposit in the compost pit.

The solid waste generated in the neighbourhood is collected and disposed.

Our body infected with a virus in a variety of ways including:

• Being bitten by an animal infected with a virus
• Being bitten by an insect infected with a virus, such as with West Nile virus
• Breathing in air-borne droplets contaminated with a virus
• Eating food or drinking water contaminated with a virus
• Having sexual contact with a person who is infected with a sexually transmitted virus
• Sharing needles for tattooing or drug use with an infected person
• Touching infected feces or body fluids and not washing your hands before eating or touching your mouth, eyes or nose
• Touching surfaces contaminated with a virus
• Transmission of a virus from an infected mother to her baby during pregnancy or delivery

The Panchayat/Municipal Corporation should filter the water and chlorinated before sending through pipes.

Organisms that can cause diseases are viruses, bacteria, fungi, protozoans, and worms.
