A cost curve is a graph of the costs of production as a function of total quantity produced. In a free market economy, productively efficient firms use these curves to find the optimal point of production (minimizing cost), and profit maximizing firms can use them to decide output quantities to achieve those aims. There are various types of cost curves, all related to each other, including total and average cost curves, and marginal (“for each additional unit”) cost curves, which are equal to the differential of the total cost curves. Some are applicable to the short run, others to the long run.
Q3. “Forests” is listed in the __________ list given in the Seventh Schedule in the Constitution of India.

Q5. ________ was imprisoned for the rest of his life by Aurangzeb.

The British government appointed the Simon Commission in 1927 for enquiry into the working of the Montagu-Chelmsford Reforms (Mont-Ford Reforms).It was an all white commission and not even a single Indian was its member. The people boycotted this commission. When the commission came to Lahore, Lala Lajpat Rai and some other people greeted them with black flags and the slogan “Simon go back”. The British police gave severe lathi blows to Lala Lajpat Rai and the others.
Q7. _________ is an example of intrusive igneous rock.
Duns are elongated valleys found between the Himalayan and Shivalik mountain ranges. Unlike typical river valleys, duns have a structural origin and are covered with boulders and gravel originating from the erosion of the Himalayas and the Shivalik uplands. Major duns found in the region are Dehra, Kohtri, Chaukham, Patli and Kota. The dun of Dehra is the biggest with a length of 35 km and width of 25 km.
Q9. A multicellular organism grows by ____________.
A multicellular organism grows because cell division increases the number of cells in it. As the organism develops and its cells divide, many of the cells become specialized, and most of them continue to divide.
Q10. The male sex organs in a flower is the __________.
The flower is the reproductive unit of some plants (angiosperms). Parts of the flower include petals, sepals, one or more carpels (the female reproductive organs), and stamens (the male reproductive organs).
The Female Reproductive Organs:
The pistil is the collective term for the carpel(s). Each carpel includes an ovary (where the ovules are produced; ovules are the female reproductive cells, the eggs), a style (a tube on top of the ovary), and a stigma (which receives the pollen during fertilization).
The Male Reproductive Organs:
Stamens are the male reproductive parts of flowers. A stamen consists of an anther (which produces pollen) and a filament. The pollen consists of the male reproductive cells; they fertilize ovules.
Q11. In animals like Annelids, Molluscs, organs have associated to form functional systems, each system concerned with a specific physiological function. This pattern is called ________ system level of organization.
प्राणी में जैसे ऐनेलिड,मोलस्क,के अंग मिलाकर तंत्र के रूप में शारीरिक कार्य करते हैं | प्रत्येक तंत्र एक विशिष्ट कार्य करता है | इस तरह कि सरंचना_______के स्तर का संगठन कहा जाता है |
Muscular force is a type of contact force ( any force which act after contact ) . when any force applied by using of muscles like arms or legs is known as muscular force .
Example :- if you lift a brick from ground , then your muscles do work for lifting it hence, here muscular force applied by arms . similarly , pulling bed , door, riding cycle etc are example of muscular force.
Q13. The force of friction between two surfaces will increase if:
दो सतहों के बीच लगने वाला घर्षण बल बढ़ता है यदि :
(a) a layer of lubricant is kept between the two surfaces/ दो पृष्ठों के बीच स्नेहक की परत लगाई जाए
(b) the two surfaces are pressed harder/ दोनों पृष्ठों को बलपूर्वक दबाया जाए
(c) air gap is created between the two surfaces/ दो पृष्ठों के बीच हवा का अंतराल रखा जाए
(d) irregularities on both the surfaces are removed/ दोनों सतहों की अनियमितता को हटा दिया जाए
Since the friction is due to the interlocking of irregularities in the two surfaces which slide with respect to each other, it is obvious that the force of friction will increase if the two surfaces are pressed harder.
