Let us assume the length of paper to be 7x and width of paper to be 5x.
Width of paper= 20.5 cm
5x= 20.5
x= 20.5/5
=4.1cm
Length of paper= 7x
= 7*4.1
=28.7 cm
Therefore, the length of the sheet is 28.7 cm.

Laboratory Thermometer: Laboratory thermometer is used to measure the temperature. The scale of temperature is graduated generally from –10°C to 110°C over the glass tube. Each division of temperature scale is further divided into 10 parts to read fraction of temperature.
Clinical Thermometer: Clinical thermometer is used to measure the body temperature. The scale of temperature is graduated from 35°C to 42°C and or from 94°F to 108°F. The temperature of human body always remains within this range and this is the range on the clinical thermometer. There is a kink near the bulb of clinical thermometer which prevents the automatic fall of mercury level.
Digital Thermometer: In digital thermometer, reading of temperature is displayed digitally as in digital watches. This is safer because no mercury is used in this. It is important to note that mercury is a highly toxic substance.

Autotrophic Nutrition
Auto means self and trophos means nourishment. Plants are called autotrophs because they make their food themselves. The making of food for themselves is called the Autotrophic nutrition. Autotrophic nutrition is found in green plants, and in some bacteria.
Heterotrophic Nutrition
The word Heterotrophic is the combination of two words i.e. Hetero + Trophos. Hetero means ‘others’ and ‘trophos’ means nourishment. If organisms depend on others for their food, such a mode of nutrition is called Hetetrophic Nutrition.
Animals cannot make their food themselves. They depend for food upon plants. Therefore, nutrition in animals is called Hetetrophic Nutrition. Animals are known as Heterotrophs.
Saprotrophic Nutrition
The uptake of nutrients by organism from dead and decaying matter in the form of solution is called the saprotrophic nutrition. The organisms which use saprotrophic mode of nutrition are called saprotrophs. For example: fungi.

The conditions for photosynthesis are sunlight, chlorophyll, carbon dioxide and water.
Factors affecting the rate of photosynthesis are (i) Light (ii) Carbon dioxide (iii) Water (iv) Temperature (v) Mineral elements.
The process of photosynthesis takes place in the green leaves of a plant. The carbon dioxide gas required for making food is taken by the plant leaves from the air which enters the leaves through tiny pores called stomata. Water required for making food is taken from the soil which is transported to the leaves from the soil through the roots and the stem. The sunlight provides energy required to carry out the chemical reactions involved in the preparation of food. The green pigment called chlorophyll absorbs sunlight energy.
The main difference between total parasite and partial parasite is that the total parasite totally depends on the host for its growth, survival, and reproduction whereas the partial parasite depends on the host only for a certain requirement of their life such as water and shelter.
