Higher temperature means more vibrations. As temperature of metal increases, the thermal vibrations in the lattice increase causing increase in collisions of electrons and slowing down the electron flow which means increase in resistance. Hence, with rise in temperature conductivity of metal decreases.

Plants have two different types of 'transport' tissue. Xylem transports water and solutes from the roots to the leaves, phloem transports food from the leaves to the rest of the plant.
Plants use two different strategies; transpirational pull and root pressure for the transportation of water and minerals during day and night.
Root Pressure is the positive pressure created by the movement of water from the roots to the soil for upward movement of water. The effect of root pressure in the transport of water is more important at night.
Transpiration pull is the pull of water as a result of tension created by transpiration in the aerial parts of the plant. It is the major driving force of water movement upwards in a plant during the day. Transpiration is the process by which water evaporates from the leaves, which results in more water being drawn up from the roots.

Least count of ammeter:
The smallest value of current that can be measured
For example:Let us calculate Least count of ammeter- 0-300mA
Least count=range of ammeter divided by number of division
Refer attachment 1:for ammeter picture
Small divisions=30
suppose there are 30 division then, least count is
=300/30=10mA
Least count of Voltmeter:
For example let us calculate least count of Voltmeter 0-15volts.
Please refer to Attachment2 for voltmeter picture
Main division 15
sub division 30
least count=15/30
=1/2=0.5
Least count of this voltmeter is 0.5

Biodiversity refers to diverse flora and fauna that exist in a given area. Plants, animals and human beings are interdependent. It is necessary for human beings as we get fresh air, water, food, etc., from them. Thus, the existence of human beings depend on them.

This is because it is easier to obtain metals from their oxides (by reduction) than from carbonate or sulphide ores. So, before reduction the ore must be converted into metal oxide which can then be reduced. Calcination or roasting is done depending on the nature of ore, to convert the ore into oxide. A carbonate ore is converted into oxide by calcination whereas a sulphide ore is converted into oxide by roasting.

- Fossil fuels are formed by natural processes of decomposition of dead and buried plants, animals and other organism.
- They got buried under oceans and layers of earth many millions of years ago and with time, high pressure and high temperature they formed fossil fuels.
- The fossil fuels are found in mines
- Fossil fuels contain high percentages of carbon and mainly include coal, petroleum and natural gas
