(4) Dilation of pupil of the eye.

(1) Removal of organisms from any tropic level of a food chain or food web disturbs the ecosystem and leads to ecological imbalance. 

(2) If we remove predators from food web, the prey population will increase enormously as there is no natural control over them. 

(3) The producers population will decrease rapidly as the organisms feeding on them increase. 

(4) After few generations the prey population also begins to decrease as some of the preys begin to die due to starvation. 

(5) Some adaptations may also be developed by the organisms to bring the ecological balance. 

(6) But it may take some generations, till that the ecosystem will be disturbed and imbalanced.

(1) In plants all parts like root, stem, leaves, etc., perform respiration individually, while in animals either the general body surface or specific organs like skin, gills, lungs, etc., are involved in respiration.

Experiment to prove the role of palate in recognizing taste : 

Aim : To prove the role of palate in recognizing taste. 

Apparatus : Sugar crystals, Stop watch. 

Procedure : 

(1) Place some sugar crystals on the tongue. 

(2) Keep mouth opened and see that tongue does not touch the palate. 

(3) Record the time from the moment we placed the crystals on the tongue till we get the taste by using stop watch. 

(4) Now repeat the test by placing the sugar crystals on the tongue pressing it against the palate. 

(5) Record the time from placing sugar crystals to getting the taste. 

Observation : From the above activity we know that taste can be identified easily when the tongue is pressed against the palate. 

Result : We can easily identify the taste of the substance we can identify the taste of it in lesser time.

Correct option is B) wicked

Correct option is B) occupied

(1) Taste can be identified easily when the tongue is pressed against the palate, as we know tongue is sensory in function and has taste buds. 

(2) These taste buds are tiny papillae with an opening on top, within which there are several taste sensitive cells (receptors). 

(3) When the tongue is pressed against the palate, the food substance is pressed against the opening of the taste bud letting it to reach the taste cells and triggering the taste signals. 

(4) Finally the taste is recognised very fast.

(a) Charles Darwin. 

(b) He made his observations in Galapagos Islands.

(1) Trait is a separate variant of an organism. 

(2) Mendel hypothesized that characters were carried as 'traits'. 

(3) An organism always carries a pair of factors for a character. 

(4) He also hypothesized that distinguishing traits of the same character were present in the population of an organism. 

(5) He assumed that the traits shown by the pea plants must be in the seeds that produced them. 

(6) These seeds must have obtained that traits from their parent plants. 

(7) For example for the colour of seed the distinguishing traits were yellow and green.

Correct option is B) significant

A. A is true but R is false. 

(1) Pyramids and food chain indicate how energy is passed from one organism (producers) to another in an ecosystem. 

(2) Each pyramid and food chain show the relationship between organisms and their food. 

(3) A food chain shows who eats what in a particular habitat. 

(4) Pyramid indicates the number of organisms, the amount of biomass and the flow of energy at each trophic level.

The hypophysis is divided into two portions: the adenohypophysis, or anterior hypophysis, and the neurohypophysis, or posterior hypophysis.

In the adenohypophysis two hormones that act directly, the growth hormone (GH) and the prolactin, and four tropic hormones, i.e., hormones that regulate other endocrine glands, the adrenocorticotropic hormone (ACTH), the thyroid-stimulating hormone (TSH), the luteinizing hormone (LH) and the follicle-stimulating hormone (FSH) are produced.

The neurohypohysis stores and releases two hormones produced in the hypothalamus, oxytocin and the antidiuretic hormone (ADH, or vasopressin).

We offer prayers to plants and animals because both are very important in ecosystem. Without plants there is no scope of life on earth and also plants and animals are interdependent. Hence the worship both plants and animals. 

Example : (i) Peepal tree gives lot of oxygen and gives place to many animals. 

(ii) Cow is worshipped because it gives milk. It is wholesome food for new born babies who are lack of mother feed.

D. There is a Capital Account Surplus of 50 million US Dollars.

D. law and order

In childhood deficient GH secretion may lead to delayed growth and in severe cases to nanism (dwarfism). Excessive production of GH in children may cause exaggerated osseous growth and gigantism. In adults GH excess (for example, in hypophiseal cancer or in people that wrongly ingest GH as a nutritional supplement) may lead to acromegaly, excessive and disproportional growth of the bone extremities, like the skull, the maxillaries, the hands and the feet.

(c) Protein – calorie malnutrition 

(b) 

(i) Kwashiorkor disease : 

(1) This is due to protein deficiency in diet. 

(2) Body parts become swollen due to accumulation of water in the intercellular spaces. 

(3) Very poor muscle development, swollen legs, fluffy face, difficult to eat, diarrhoea, dry skin are the symptoms of this disease. 

(ii) Marasmus : 

(1) This is due to deficiency of both proteins and calories.

One of the most critical skills in effective communication is active listening. Improving our active listening skills will help us succeed. Developing this soft skill will help build and maintain relationships, solve problems, improve processes and retain information such as instructions, procedures and expectations and this soft skill will help to improve our personality.

Flexing is defined as the movement to decrease the angle between parts. Flexing one's muscles usually, result in bringing bony parts closer together. For example, forward flexion brings the shoulder girdle and pelvis closer together

The epidermis consists of a stratified squamous epithelium. That means it consists of layers of flattened cells. It is the uppermost or epithelial layer of the skin. It acts as a physical barrier, preventing loss of water from the body and preventing entry of substances and organisms into the body. Its thickness varies according to a body site.

(A) Fertilization 

(B) Testes in scrotum 

(C) By dissolving the membrane with chemicals. 

(D) The middle piece has mitochondria which produce energy for the movement of the sperm. 

The correct answer is 1 and 2 only.

• Right to the City
  • It is an agreed human right and the UN-Habitat monitors the commitments made by each country in this regard. Hence, Statement 1 is correct.
  • The right to the city is far more than the individual liberty to access urban resources.
  • It is a right to change ourselves by changing the city.
  • It is, moreover, a common rather than an individual right since this transformation inevitably depends upon the exercise of a collective power to reshape the processes of urbanization. 
  • The Right to the City means the “right of all inhabitants, present and future, permanent and temporary to use, occupy and produce just, inclusive and sustainable cities, defined as a common good essential to a full and decent life.”
  • The original definition of the right to the city goes beyond basic human rights and access to resources.
  • It is a renewed access to urban life, one that empowers city dwellers’ to shape the city as they see fit through rights to participation and active civic engagement. Hence, Statement 2 is correct.

• In 1996, the Istanbul Declaration and the Habitat Agenda reinforced the responsibilities of all governments to the provision of adequate housing, as exemplified by their creation of ministries or agencies, by their allocation of resources, and by their policies, programs, and projects.
• It also stated that the provision of the right to adequate housing required joint action by government organizations, communities, and local authorities, as well as partner organizations and entities of the international community.
• Unauthorized Colonies (UACs) are a specific form of unplanned housing – built on land which is either not zoned for residential purposes or does not fall under the ambit of the development area of the city's master plan. Hence, State can deny and public service or facilities to the unauthorized colonies in the city. Hence, Statement 3 is not correct.
