Immortality means the ability to live forever, without death.

The people of Arunachal Pradesh believe that it will be possible for the soul of the departed person enter ‘the house of the sun’. They hope the soul will be able to ‘walk into the golden east’. So they place the dead (with feet) pointing to the west.

“Small Towns and Rivers’ is written in free verse. Since there are irregular lengths of lines and no rhyme, the reading of the poem is almost like a story-telling. Each stanza has a different number of lines and there is no order for mixing up the short and long lines.

The poem is not confined by an obvious rhythm so we feel there is a kind of freedom.We are free to imagine the widespread setting of the North-eastern terrain of mountains and rivers, mists, golden sunlight and the town by the river.

Meat: Meat is rich in protein and also contains many minerals like iron, zinc, vitamins and selenium. It also contains vitamins needed for human diet.

Milk products: Milk is produced by dairy animals which is an emulsion of fat and lactose. Milk also contains enzymes which are destroyed during pasteurization.

Milk is a rich source of vitamin A, B„ Bp and deficient in Vitamin C. Due to its high nutrition value, it serves as a . complete food for infants. Dairy products such as yoghurt, cheese, butter, ice cream, condensed milk, curd, and milk powder processed from milk make dairy, a highly farming attraction.

Rinderpest, foot and mouth disease, cow pox, hemorrhagic fever, anthrax.

(I) Dairy breeds or Milch breeds: They are high milk yielders with extended lactation. Eg., Sindhi, Gir, Sahiwal, Jersy, Brown Swiss, Holstein cattle.

(II) Draught purpose breeds: Bullocks are good for draught purpose. Eg. Kangayam, Malvi.

(III) Dual Purpose breeds: Cows are meant for yielding more milk and bullocks are used for better drought purpose Eg. Ongole, Hariana.

Dairying is the production and marketing of milk and its products. Dairy operation consists of proper maintenance of cattle, the collection and processing of milk and its by-products.

Removal of stamens of a bisexual flower will not affect pollination of its intact pistil and formation of fruit. Cross-pollination has occurred leading to fertilization.

2. ‘it is always the same In summer and winter With the dust flying Or the wind howling down the gorge’

Interspecific hybridization. In this method of breeding mating is between male and female of two different species. The progeny obtained from such crosses are different from their parents, and may possess the desirable traits of the parents.

Multiple ovulation embryo transfer technology (MOET). It is another method of propagation of animals with desirable traits. This method is applied when the success rate of crossing is low even after artificial insemination. In this method Follicle stimulating hormone (FSH) is administered to cows for inducing follicular maturation and super ovulation. Instead of one egg per cycle, 6-8 eggs can be produced by this technology.

The eggs are carefully recovered non-surgically from the genetic mother and fertilized artificially. The embryos at 8-32 celled stages are recovered and transferred to a surrogate mother. For another round of ovulation, the same genetic mother is utilized. This technology can be applied to cattle, sheep and buffaloes. Advantage of this technology is to produce high milk yielding females and highquality meat yielding bulls in a short time.

Artificial insemination. Artificial insemination is a technique in which the semen collected from the male is injected to the reproductive tract of the selected female.

A) Food grains

Answer is (A) Broilers

D) Increase in milk production

(A) 62°C for 30 mnts

Answer is (A) 62°

There will be inconveniences in getting haircut. Either, we will have to go to distant places or arrange for a haircut ourselves, or the hair will grow too long.

(B) Anabaena and Nostoe

Animal husbandry is the practice of breeding and raising livestock cattles like cows, buffaloes, and goats and birds etc. that are useful to human beings.

(b) Hermaphroditic but not self-fertilizing

The blood consists of plasma [60%] and blood cells [40%], red blood cells, white blood cells, and platelets. RBCs are loaded with red pigment, nucleated and oval in shape. Leucocytes are nucleated, and circular in shape.

Correct Answer is: (b) False

Ommatidia   .

If an eye is made of many eyes, it is a compound eye. It has many visual receptors unlike a simple eye which has only one visual receptor. The photoreceptors of the cockroach consists of a pair of compound eyes at the dorsal surface of the head. Each eye is formed of about 2000 simple eyes called the ommatidia (singular: ommatidium), through which the cockroach can receive several images of an object. This kind of vision is known as mosaic vision with more sensitivity but less resolution.

The Nervous system is divided into the Central Nervous System [CNS], the Peripheral Nervous System [PNS], and the Autonomous Nervous System [ANS], Peripheral Nervous System consists of 10 pairs of cranial nerves and 10 pairs of spinal nerves. Autonomic Nervous System is divided into sympathetic and parasympathetic nervous system. They control involuntary functions of visceral organs.

Correct Answer is: (c) uric acid

• The dorsal wall of the intestine of earthworm is folded into the cavity as the typhiosole.
• This fold contains blood vessels and increases the absorptive area of the intestine.

The receptors are simulated by a group of slender columnar cells connected with nerves. The photoreceptor are found on the dorsal surface of the body. Gustatory and olfactory receptors are found in the buccal cavity. Tactile receptors, chernoreceptors and thermoreceptors are present in the prostomium and the body wall.

The bibbed mass of nervous tissue called suprapharyngeal ganglia lies on the dorsal wall of the pharynx in the 3 segment. It is referred as the brain. In the 4th segment, the sub-pharyngeal ganglia is found. The brain and the sub-pharyngeal are connected by a pair of circum-pharyngeal connectives. The double ventral nerve cord runs backward from the sub-pharyngeal ganglion. The brain and other nerves in the ring integrates sensory inputs and command muscular responses of the body.

In gardens, earthworms can be traced by their fecal deposits known as worm castings on the soil surface. 

The earthworms can be identified using the following characteristics:

• Long and cylindrical narrow body. 
• Bilateral symmetry
• It is light brown in colour with purple tinge at the anterior end.
• The division of body into many segments or metameres.
• The dorsal surface of the body is marked by a dark mid dorsal line.
• In mature worms, segments 14-17 may be found swollen with a glandular thickening of the skin called the clitellum.

When we put food in our mouth that response is a voluntary response and after that, the process of digestion and excretion comes under the involuntary response.

Nastic Movement: They are non-directional curvature movements of turgor or growth when the movements are determined by the structure of the responding organ irrespective of the direction of structure which is generally diffused. e.g., Drooping and folding of leaves in a sensitive plant in response to shock (seismonasty).

Curvature Movement: They are changes in orientation of some plant parts in relation to others caused by intrinsic or external stimuli, e.g., sleep movement or nyctinasty of legume leaves, bending of stem towards the light.

(a) Gravity.

(b) Light.

Nose and Tongue.

The undigested particles of food along with earth passed out through the anus of the earthworm are called worm casting.

Tropism means movement of the part of the plant either in the direction of the stimuli or away from the stimuli. Stimuli can be light, gravity, water or chemicals. For example, in case of phototropism means movement of part of the plant in the presence of light, in this two type of movement is seen shoots moves or grows in the direction of light whereas in case of roots, it grows in the direction opposite to the light. So, with different stimulus plants show different tropism or directional movement.

Tropism is the movement in the presence of any stimulus. If the movement is towards the stimulus then it called positive tropism and if the movement is away from the stimulus then it is called negative tropism.

In nastic movement, there is not directional movement in the presence of stimuli. These movement always occur in the particular direction irrespective of the type of stimuli.

In earthworms, respiration takes place through the body wall by the moist skin diffusion, oxygen diffuses through the skin into the blood while carbon dioxide from the blood diffuses out.
