1 DETERMINED character traits EG he has a trait in his work
 2.it tells US about dna.height, etc eg your height is according to your genes
3 INHERITANCE of pattern-dominant RECESSIVE his is a dominant recessive 

Our eye contains of eyelids, eyelashes,eyebrows and lachrymal glands. A thin LAYER , called conjunctiva covers the front portion of the eye. The eye ball is LOCATED in the  eye socket . only 1/6 portion of the eye ball is visible to us .
                  
             Eye has three main layers. they are sclerotic layer or sclera , choroid layer and retina. the outer most thick tough ,fibrous , non-elastic and white coloured layer is sclera . the sclera bulges and forms cornea . the end of sclera connects to the optic nerve . the second layer is choriod layer. this layer is black in colour and contains a lot if blood VESSELS. ait ENCLOSES the eye except the part pupill. the part formed by the choroid layer around the PUPIL is iris. Radial and circular uscles are present in the iris . biconvex lens is present immediately behind the pupil is attached to the ciliary muscles and suspensory lingaments .
                                 the lens dividesd the inner eye ball as aqueous chamber and vitreous chamber. aqueous chamber is filled with water like fluid whereas vitreous chamber is filled with jelly like fluid .
                           retina contains the cels , called rods and cones . the area of the vision , called blind spot  and the area of the best vision , called yellow spot  are present in the present in the retina. The yellow spot is called macula or fovea

The arrangement of VEINS on the SURFACE of the leaf is CALLED venation.
reticulate venation-the veins are arranged in a PATTERN that FORMS a network
parallel venation-the veins are arranged parallel to each other 

Biosphere is the 4th domain of the sphere the hydrosphere,atmosphere and the LITHOSPHERE form the biosphere. these 3 DOMAINS provide everything for the existence of living things they are known as biosphere reserves.
the place where WILDLIFE is protected and SAFEGUARDED is called wild life SANCTUARY

Organic COMPOUNDS ALWAYS contain carbon while most inorganic compounds do not contain carbon. ALSO, ALMOST all organic compounds contain carbon-hydrogen or C-H bonds.

It's so because the PRESSURE in the VEINS is FAR LESS then that in the ARTERIES

The WORDS “organic” or “natural” in this case SIMPLY means that the PRODUCT is only minimally processed, and the nutrients remain bound up in their natural forms, rather than being extracted and refined. In the case of FERTILIZER, “organic” does NOT refer to the standards of processing associated with food.Organic fertilizer is usually made from plant or animal waste or powdered minerals. Examples include manure and compost, as well as bone and cottonseed meal. They are usually sold as “soil conditioners” rather than as fertilizer, because the nutrient ratios are difficult to guarantee. Organic fertilizers may be processed in a factory, or, in the case of manure and compost, at a farm

Traditional irrigation methods are canal irrigation, WELLS persian WHEEL, INCLINED plane irrigation method, etc

Mouth   - food enters and CHEWED and mixed with saliva
buccal CAVITY -saliva is mixed with food to make easy path of food
epiglottis -a trachea which SHUTS over wind pipe and sends the food to esophagus
esophagus -food pipe which takes food to STOMACH by wave like movement
stomach-food gets churned and mixed with H Cl acid to kill BACTERIA
 small intestine-absorbs nutrients present in the food by small finger like                                                                                                       projections called villi
large intestine-absorption of water and sends waste-material to rectum and anus
anus-ex-creates waste water

Due to construction of large dams
1) the nearby flora and fauna is DESTROYED and they become homeless
2)the villagers whose HOME is the village in which they live are VACATED with the promise of riches and they lose their jbo which they werfe doing WELL in the village and after coming to the city they become homelss or jobless or they may have do extra work to survive in the cit and the future of their kids will be lost by going to do job

Teri dam is ONE of the TALLEST dam in INDIA and the world.it is built on the river bhagrathi,uttarkand,india.

When your hart beats, it pumps blood round your body to give it the energy and  oxygen  it needs.as the blood moves,it pushes  against the SIDES of the blood  vessels  . the STRENGTH  of this pushing is your blood pressure.if your blood pressure is  too  high it put's extra strain on your  arteries  and this may lead to heart attacks  and strokes.

1)systolic pressure  :- 
                                       when your heart beats it contracts and pushes blood through the arteries to the rest of your body this force creates  pressures on the arteries is called  systolic  pressure.
2) disytolic  pressure:- 
                                          the minimum level of  blood pressure MEASURED  between  contraction of the heart.  it may VARY with age ,gender, body WEIGHT, emotional  state , and other  factor.

Homeostasis is a key concept in understanding how our body works. It MEANS 'keeping things constant', and comes from two GREEK words homeo, meaning 'similar' and stasis, meaning 'stable'. A more formal definition of homeostasis is: a characteristic of a system that REGULATES its INTERNAL environment and TENDS to maintain a stable, relatively constant condition of properties.

Still research is GOING on and there is no clear explanation for these lines.
The Nazca Lines are found in the desert near the town of Nazca in PERU. There are SEVERAL hundred Nazca line figures, some geometric shapes, others APPEARING as representations of animals and other creatures. Many explanations have been put forth since passengers in airplanes flying over the region first noticed the strange "runways" and art FORMS. Some have suggested they are just works of art, an ancient culture's homage to the beauty and diversity of nature. Others believe there was a more practical purpose, such as astronomical calendars or representations of constellations, or they were spiritually inspired as worship of deities. Others have suggested other worldly origins. In fact, the explanations of these amazing creations have become almost as creative as the Nazca lines themselves.

Monocot: 
Rice, Wheat, Maize, Bamboo, Palm, Banana, Ginger, Onion, Garlic, Lilies, Daffodils, Iris, ORCHIDS, Bluebells, Tulips, AMARYLLIS. 

DICOT: 
Magnolias, Nutmeg, Cinnamon, Avocado, BLACK PEPPER, Water Lily, Star Anise, Hornwort.

Machines USED to burn hospital waste at high temperature are CALLED INCINERATORS,and the process called INCINERATION.

The reproduction in which FUSION of GAMETES TAKES place it is CALLED SEXUAL reproduction.
the reproduction in which fusion of gametes does not takes place it is called asexual reproduction.

Cilia
are tail-like PROJECTIONS found only in EUKARYOTIC cells (that is, the cells of animals). There are two types: motile (that is, mobile) and non-motile. The two FUNCTIONS of these types of projections are to either move through the cell or to act as sensory organisms. Along with flagella, these projections are part of a group of organelles (that is, cell parts) known as undulipodia

2  the villi play a role in digestion, they ALSO are essential for the absorption of DIGESTED nutrients. The cells of the villi and another part of the small intestine, known as the crypts, transport food from the digestive tract into the bloodstream, where they can be used by the body. The villi aid in absorption by increasing the surface area of the intestine and contain specialized cells which transport different types of nutrients into the blood.

Have regular family meals. Respect the meal times. Let it be a bonding time with no other distractionsBreakfast is another great time for a family meal, especially since kids who eat breakfast tend to do better in school. Ensure that your child never skips breakfast. It is the most important meal of the day.Cook more meals at home. Save dining out for SPECIAL occasions.Get kids involved. Children enjoy HELPING adults to shop for groceries, selecting what goes in their lunch box, and preparing dinner. It’s also a chance for you to teach them about the nutritional values of different foods, and (for OLDER children) how to read food labelsMake a variety of HEALTHY snacks available instead of empty calorie snacks. Keep plenty of fruits, vegetables, whole grain snacks, and healthy beverages (water, milk, pure fruit juice) around and easily accessible so kids become used to reaching for healthy snacks.Limit portion sizes. Don’t insist your child cleans the plate, and never use food as a reward or bribe.Picky eaters are going through a normal developmental stage, exerting control over their environment and expressing concern about trusting the UNFAMILIAR. Many picky eaters also prefer a “separate compartmented plate,” where one type of food doesn’ttouch another.

The enzymes that are secreted by STOMACH are called by gastric enzymes.the stomach SECRETES pepsinogen that is CONVERTED into pepsin by the action of HYDROCHLORIC acid.

It is a SURGICAL OPERATION which is used for the PERMANENT birth control

AMINO ACIDS, GLYCEROL , FATTY ACIDS ,and  GLUCOSE . are the END PRODUCTS
 proteins are BROKEN down into amino acids 
the fats are broken down into fatty acids and glycerol 
the carbohydrates are broken down to maltose by salivary amylase further maltose is broken down by MALTASE into Glucose 

Before a cell divides, its nucleus must DIVIDE. But before that happens, the chromosomes must have become double. So the first stage is that DNA which the chromosomes CONTAIN must replicate , i.e. become double, by MAKING copies of itself.The 2 strands of the DNA double helix can separate, under the influence of special enzymes in the nucleus, but each half remains attached along its length, like the 2 sections of a zip, because the sides of the strands are strongly joined.Each strand then acts as a basis for rebuilding the missing other strand from which it has been separated. It is said that each strand forms a template on which it reforms its complementary strand. Enzymes within the nucleus match the appropriate base, which is already attached to strand side subunits, so that A fits against T, G against C, T against A and C against G, according to shape.Other possibilities are not allowed, so the copying process is accurate in the vast majority of cases.The result is that one double strand is converted into two identical double strands.It is interesting to note that each "new" double strand is in fact half composed of a section of the previous DNA molecule, together with a completely new section built up from INDIVIDUAL bases. Because of this, it is called semi-conservative replication.

We can MAKE COLLECT for under GROUD WATER

Recycling of waste materials
reuse of plastic, GLASS etc.
buy materual which U need 
USE of CLOTH bag instead of plastic bags

The blue CROSS society is an ANIMAL charity welfare based in CHENNAI. it was established in 1959 by CAPTAIN sundaram. the society was registered by in 1964.

Biosphere:- the combination of animal,plant and non-living being make the planet earth by their interaction known as biosphere.

biotic components:- living things CONSTITUTE the biotic components of the biosphere.

abiotic components:-the air,water and soil from the non-living biotic components of the biosphere.air is called hygrosphere and water is known as hydrosphere.

air:- air is a mixture of MANY gases oxygen,CARBON DIOXIDE,nitrogen and water vapour.

carbon dioxide fixation:- green plants converts carbon dioxide into glucose in the PRESENCE of sunlight.

Answer :-

First of all, what are traits ?

Ans - Traits can be defined as the BEHAVIOUR and RESPONSE of an organism towards its surroundings, it's feeding habits and it's habitat.

The 3 ways in which individuals with a particular trait may increase in POPULATION are as follows :-

• The organisms have a better sort of adaptability to the environment in which they exist and are able to survive and reproduce.

• The organisms are able to resist the diseases and remain healthy.

• Geographical isolation of a group of organisms by various types of barriers (such as mountains, rivers, seas, ETC).Such a type of isolation leads to the isolation of reproductive practices within the organisms as a result of which, no gene flow occurs among the SEPARATED group of organisms.

Obviously option (B) , HUMAN belong to the species Homo-Sapiens who are our ancestors . The variations are DUE to mutations and others environmental changes to survive!
