Ques 1: Explain in brief the cause of shoots of the plant bending towards light.
Ans: 
Stems are positive phototropic and bend towards the direction of light. The movement is due to occurrence of more auxin on the darker side and lesser auxin on the illuminated side. As a result, there is more growth on the darker side which causes the stem to bend towards light.

Class 10 Science: CBSE Sample Question Paper- Term I (2019-20) - 1 | CBSE Sample Papers For Class 10Principle 

It works on the principle of magnetic effect of current. When a current-carrying conductor is placed perpendicular to the magnetic field, it experiences a force. 

Working 

Consider at the beginning, the arms AB and CD are perpendicular to the direction of applied magnetic field. 
(a) Initially, let the current in the coil flows along the path ABCD. Then, according to the Fleming's left-hand rule, a downward force acts on the arm AB pushes it downwards and an upward force on arm CD pushes it upwards. These forces cause the coil to rotate in anti-clockwise direction about its own axis. 
(b) After completing half rotation, the position of split rings interchanges due to which direction of current in the coil gets reversed and current flows along the path DCBA. Again according to Fleming's left-hand rule, the force acting on the arms AB and CD also get reversed. This makes the coil to rotate and complete the next half cycle of rotation in the same direction. Thus, the interchanging of split rings at each half turn, makes the coil to rotate continuously in the same direction as long as the current is passing through it. Function of split ring It reverses the direction of current in the armature coil. 
Or 
A current induces in a solenoid if a bar magnet is moved relative to it. This is the principle of electromagnetic induction. 
(i) When a bar magnet is pushed into a coil of insulated copper wire, a current is induced momentarily in the coil. As a result, the needle of the galvanometer deflects momentarily in a particular direction. 
(ii) When the bar magnet is withdrawn from inside the coil of the insulated copper wire, a current is again induced momentarily in the coil in the opposite direction. As a result, the needle of the galvanometer deflects momentarily in the opposite direction. 
(iii) When a bar magnet is held stationary inside the coil no current will be induced in the coil. Hence, galvanometer will show no deflection.

Ques 33: (a) Draw a diagram of an excretory unit of human kidney and label the following Bowman's capsule, glomerulus, collecting duct and renal artery. (b) Write the important function of structural and functional unit of kidney. (c) Write any one function of an artificial kidney.

Ques 35: Draw the labelled diagram of dome type bio-gas plant and explain its construction and working. Or Energy from various sources is considered to have been derived from the sun. Do you agree? Justify your answer.
Ans: The diagram of dome type bio-gas plant is shown as

Class 10 Science: CBSE Sample Question Paper- Term I (2019-20) - 1 | CBSE Sample Papers For Class 10
Construction 

The bio-gas plant is a. brick and cement structure having the following five sections 

  1. Mixing tank: It is present above the ground level. 
  2. Inlet chamber: The mixing tank opens underground into a slopping inlet chamber. 
  3. Digester: The inlet chamber opens from below into the digester which is a huge tank with a dome like ceiling. The ceiling of the digester has an outlet with a valve for the supply of bio-gas. 
  4. Outlet chamber: The digester opens from below into an outlet chamber. 
  5. Overflow tank: The outlet chamber opens from the top into a small over flow tank. 

Working 

  • The various forms of bio-mass are mixed with an equal quantity of water in the mixing tank. This forms the slurry. 
  • The slurry is fed into the digester through the inlet chamber. 
  • When the digester is partially filled with the slurry, the introduction of slurry is stopped and the plant is left unused for about two months. 
  • During these two months, an anaerobic bacterium present in the slurry decomposes or ferments the bio-mass in the presence of water. 
  • As a result of anaerobic fermentation, bio-gas is formed, which starts collecting in the dome of the digester. 
  • As more and more bio-gas starts collecting, the pressure exerted by the bio-gas forces the spent slurry into the outlet chamber. 
  • From the outlet chamber, the spent slurry overflows into the overflow tank. 
  • The spent slurry is manually removed from the overflow tank and used as manure for plants. The gas valve connected to a system of pipelines is opened when a supply of bio-gas is required. To obtain a continuous supply of bio-gas, a functioning plant can be fed continuously with the prepared slurry. 

OR 

Yes, sun is the ultimate source of energy. 
Directly or indirectly, all the forms of energy are derived from solar energy. Non-renewable Sources of Energy Fossil fuels like coal petroleum and natural gas are formed due to burial of large plants and ancient creatures whose ultimate source of energy is sun. Renewable Sources of Energy 
They are indirectly derived from solar energy such as 
(i) Energy from Flowing Water: Clouds are formed when water in lakes, rivers, seas, etc evaporates due ro solar energy. They bring rainfall and snowfall. The rain and melting snow feed rivers, streams, etc. This flowing water can be used for getting hydroelectricity. 
(ii) Wind Energy: It arises due to uneven heating of the earth's surface by the sun rays at two different adjoining places. Due to this, wind possesses kinetic energy. 
(iii) Bio Energy: Plants in the process of photosynthesis converts the solar energy into food (chemical energy). This food is consumed by animals. This, the animal wastes and remains of the plants constitute bio-mass which can be utilised as a source of energy. 
(iv) Wave Energy: The waves are generated by strong winds (due to solar energy) blowing across the sea. 
(v) Ocean Thermal Energy: Sun is responsible for the temperature difference between the water at the surface and water at depth in seas and oceans. Solar heating devices derive their energy directly from solar energy and convert it into other usable forms of energy. Thus, the energy from various sources are considered to have been derived from the sun.
