1. Global warming has been increasing. 

2. As global temperature increases, the ice in the tundra melts more. 

3. The methane that is trapped under the ice escapes into the atmosphere, increasing the global temperature. 

4. Methane is even more powerful than carbon dioxide as a green house gas. 

5. Then it is our responsibility to reduce global warming. 

6. This global warming leads to climatic changes. 

7. Hence human activities that lead to global warming are to be reduced.

Yes there are differences between the protection given to animals in zoo and wildlife sanctuaries. 

These differences are listed below:

• In zoo animals are not protected in their natural environment or habitat whereas in wildlife sanctuaries they are protected in their natural environment.
• Wildlife sanctuaries mostly aim for the protection of some particular species whereas in zoos animals are bought and they rear them but not look for protection of particular species.
• Zoos are mostly trade sought of which mostly aims for money whereas the primary goal of wildlife sanctuaries is the protection of animals and not to use them for trade related aspects.
• There are strict rules and regulations in wildlife sanctuary regarding entry of every person but the case is not same with the zoos.

Wildlife conservation and forest conservation are interrelated because conservation of forests will itself led to conservation of wildlife.

The main reason of extinction of the wildlife is their habitat destruction. Forests provide habitat to the complete wildlife and food also. They provide all the suitable conditions required by wildlife for their survival. So, if we will try to conserve forests we will conserve the habitat of wildlife and hence also conserve it.

Wildlife sanctuaries are reserved for the protection of wildlife.

Function of wildlife sanctuary- It provides protection and suitable living environment to the wild animals.

(b) Hanging oneself on horizontal bar. 

(c) Trikonasana helps in developing those muscles. 

(d) Guidance of qualified physician should be obtained before going for any corrective exercise.

Correct option is A) oxygen

Following are the steps which are necessary for wildlife:

• Firstly, we should try our best to protect the habitats of the animals. Destruction of the habitats like deforestation for our own benefits deprives many of the animals from their habitat. So, we should not cause any harm to their habitats for our own benefit.
• Practices like hunting and poaching needs to be banned and strict regulations need to be implement in order to save the lives of animals.
• Various projects for different animals which aim for saving and maintain the population of endangered species needs to be implement.
• Number of wildlife sanctuaries, biosphere reserves, and national parks needs to be increased so that we can protect them by providing them their natural habitat.
• Human intervention in their habitats needs to be in balance form which do not cause any harm to them.
• Government needs to implement strict laws against crimes related to wildlife and needs to make people aware about the importance of wildlife and how they can contribute in their conservation.

Xenon has lower ionization energy than Krypton, therefore, Xe forms compounds.

The correct answer is D) Hydrochloric acid.

Autotrophic Nutrition : The mode of nutrition in which organisms make food by themselves is called autotrophic nutrition. 

Ex: plants

The correct answer is B) Vajrasana.

The correct answer is C) Villi.

Glucose/ Carbohydrate is the food material formed in plants.

The mode of nutrition in which organisms take in nutrients in solution form from dead and decaying matter is called saprotrophic nutrition. 

Ex: mashroom

The correct answer is D) All the above.

Damage of enamel on the tooth due to action of acids in the mouth is called tooth decay.

When food remains stuck in teeth, bacteria feed on them. As a result, lactic acid is produced, which causes the destruction of enamel and it leaves toothache.

The correct answer is D) All the above.

Chocolates, sweets, soft drinks and other sugar products are the major culprits of tooth decay.

Carbon dioxide from air is taken in to the leaves through stomata.

Plants take carbon dioxide during photosynthesis.

The most common problems associated with the digestive tract are diarrhoea, constipation, irritable bowel syndrome, acidity, etc.

1. Bad habits like smoking, chewing of tobacco, drinking of alcohol effect our health adversely. . 

2. Drinking of alcohol can lead to liver diseases, digestive problems. 

3. It causes cancer of the mouth, throat, oesophagus arid liver. 

4. Consuming tobacco products, tobacco particles stick to teeth, gums, and skin of the mouth cavity which leads to swelling, injury, pain and also causes throat and intestine cancer.

1. Normally Bacteria present in our mouth are not harmful to us. 

2. If we do not clean our teeth and mouth after eating, many harmful bacteria begin to live and grow in it.

3. These bacteria breakdown the sugars present from leftover food and release acids. 

4. These acids gradually damage teeth. This is called tooth decay. 

5. If it is not treated in time, it causes severe toothache and in extreme cases results in tooth loss. 

6. Chocolates, sweets, soft drinks and other sugar products are major causes of tooth decay.

Acidity:

It’s a common problem associated with digestive track caused due to excess acids in stomach.

Symptoms : 

Burning sensation in chest, stomach and in throat; sour taste in mouth; upper abdominal discomfort; post meal heaviness. 

Causes : 

consuming spicy food; stress; unhealthy or irregular meals; drinking too much alcohol. 

Home remedies: 

Consuming butter milk, coconut water, eating of herbs such as ajwain, tulsi leaves, saunf, jeera and pudina leaves, cloves, jaggery

Carbon dioxide, water, sunlight and chlorophyll.

Water absorbed by the roots are transported to the leaves through the stem.

1. Plants get carbon dioxide from air through stomata in leaves. 

2. Water obsorbed by the roots are transported to the leaves through the stem. 

3. Chlorophyll captures the energy of the sunlight.

If carbohydrates are not included in our diet, our work efficiency will decrease.

Different parts of human digestive system performs different functions as mentioned below.

1. Mouth Food is taken into the body through it. It leads into Buccal Cavity. 

2. Buccal cavity contains tongue, teeth and secretions of Salivary glands. Carbohydrate digestion starts here. 

3. Pharynx is the common chamber for both digestive track and respiratory track. It leads into Oesophagus. 

4. Oesophagus is a muscular tubular structure that connects pharynx with Stomach. 

5. Stomach is a muscular sac like structure. Food is grinded well and mix with its juices. Proteins digestions tarts in the stomach. Hydrochloric acid in the stomach kills Bacteria in the food. 

6. Duodenum is the first part of the small intestine. Bile juice from liver, Pancreatic juice from pancreas enters into it and helps in digestion. 

7. Small intestine is about six metre long. Digestion of food is completed here with the help of its juices. Its inner wall have thousands of finger-like outgrowths called villi. They absorb the digested food. Blood transport it to all body parts for assimilation. 

8. Large Intestine absorbs water and minerals from the undigested food. 

9. Rectum storage point for undigested food. 

10. Anus – Fecal matter removed through it.

1. The digestive system consists of the alimentary canal and digestive glands. 

2. The total length of alimentary canal is about 9 meters. 

3. Its main parts are mouth, oral cavity/ buccal cavity, oesophagus, stomach, small intestine, large intestine, rectum and anus. 

4. The salivary glands, liver and pancreas are the digestive parts connected to the alimentary canal.

Kangaroo colony – Mob 

Lions colony – A pride Owls 

colony – A parliament

The correct answer is C) 9 meters.

The correct answer is B) Stomach.

The correct answer is A) Ingestion.

1. Carbon dioxide required for photosynthesis enters into the leaf through the stomata. 

2. Water absorbed by the roots transported to the leaf through the stem. 

3. Leaf get sunlight when it exposed to the sun. 

4. Chlorophyll is present with the leaf

1. Sun light is the source of energy in the process of photosynthesis. 

2. The solar energy is captured by the leaves and stored in the plant in the form of food. 

3. Thus, sun is the ultimate source of energy for all living organisms.

The correct answer is D) Holozoic.

The correct answer is A) Oxygen.

The steps involved in holozoic nutrition are Ingestion, Digestion, Absorption, As similation, Egestion.

The correct answer is C) Nutrition.

Plants produce sugar first, which is converted to starch and then other compounds like fats and proteins.

The correct answer is D) Cellulose.

The correct answer is B) Leaf.

1. Glucose formed in photosynthesis is converted and stored in the form of starch. 

2. So, the presence of starch in leaves indicates the occurrence of photosynthesis. 

3. It can be confirmed by testing the leaf extract with Iodine solution.

The correct answer is D) All the above.
