Two different functions performed by the pancreas in our body are: 1. Pancreas makes two hormones i.e., insulin and glycogen that regulates blood sugar level. 2. It secretes pancreatic juice that aids in the digestion of food.
Modern periodic law states that the physical and chemical properties of an element are the periodic function of the atomic number of that element. Electronic configuration of the elements play an important role in the placement of elements in the modem periodic table. The valence shell electron of an element decides its position in a particular group or period for example: if the configuration of an element is 2, 1 it means that the Li = 2, 1 It belongs to the 2nd period and 1st group.
Si = 2, 8, 4 (a) It means that it belongs to the 3rd period and 14th group. (b) The name of the element is Silicon. It is a metalloid, (i.e. element that has properties of both metals and non-metals).
The three methods by which we can reduce the problem of waste disposal are: 1. Adopting the 3R approach i.e;-Reduce, Reuse, Recycle. 2. Segregation of waste into biodegradable and non-biodegradable waste. 3. Conversion of waste into useful components like biogas and then using compost as a fertiliser.
<p>Ecosystem refers to the interaction of all the biotic and abiotic components present in a particular area. Energy flows across the trophic levels following the 10% law. Only 10% of the energy available to a trophic level is passed on to the next trophic level.Ecosystem refers to the interaction of all the biotic and abiotic components present in a particular area.

For example 10,000J energy is available to the producer.<br /> 2. Then 1000J energy will be available to the primary consumer.<br /> 3. 100J energy will be available to secondary consumer.<br /> 4. 10J energy will be available to tertiary consumers.</p>
(i) 1. Short-term exploitation will meet the demand of the present generation. 2. There will be no shortage of resources. 3. A larger aspect regarding the details of a reserve can be studied also.
(ii) 1. Long-term management of natural resources would meet the demand of present and future generations. 2. No harmful impact on the environment. 3. Equitable distribution of resources amongst the rich and poor.
<p>Rainbow is an arch of colours visible in the sky, caused by the refraction and dispersion of the suns light by rain or other water droplets in the atmosphere. The colours of the rainbow are generally said to be red, orange, yellow, green, blue, indigo, and violet.<img alt="" src="https://imagedelivery.net/HpP6TwyM91IVKvXTR1TJrw/8926c3f5-63b7-4280-1dff-c638b3324000/public " /></p>
