Question

6. Plants

are unable to use atmospheric
for preparing proteins.
7. Heat always travels from a body at higher to a body at lower
8. The degree of hotness of a body is called heat temperatures therm
of boiling water cannot be measured by a
thermome​

Answer 1

Explanation:

6.Plants need proteins and fats besides the carbohydrate. Proteins are nitrogenous substances which contain nitrogen. Although nitrogen is present in abundance in atmosphere, but plant cannot absorb atmospheric nitrogen. ... They convert gaseous nitrogen into usable form and release it into the soil..

7.Heat is a form of energy. The atoms of the system with higher temperature will gain the heat energy and the vibration of these atoms will increase. ... So, we can say that heat always flows from higher temperature to a lower temperature.

8.The hotness of an object is determined by its temperature.The temperature of boiling water cannot be measured by a clinical thermometer.
