Tissue is the group of cells with similar structure and function.In multicellular organisms tissues perform specific function at their defined place. The utility of tissues in multicellular organisms is to provide defined structure, mechanical strength, and division of labor. This division of labor makes multicellular organisms able to perform all ... Read More

Synthetic fibres catch fire easily because they are artificial polymer fibres that melt upon heating. They burn, melt and shrink in flame.

Displacement is a vector quantity.Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.

The word prokaryote is derived from the Greek word "pro" means before and "karyote" means the nucleus. Thus, prokaryote means a primitive type of nucleus. A prokaryote is a unicellular organism with a primitive type of nucleus. Prokaryotic cell lacks a membrane-bound nucleus, mitochondria, and any other membrane-bound organelle. Prokaryotes ...

Seed get diseases mainly due to fungal infections. Thus to prevent seed borne diseases, the seeds must be treated with antifungal or fungicidal solutions.

Cyclone is a huge system of air mass in which winds rotate inwardly to low atmospheric pressure.  For large cyclones, the wind pattern is in anti-clockwise direction in the northern hemisphere and a clockwise direction in the southern hemisphere.There are two types of cyclones.1) Mid-latitude cyclonesThese cyclones are the main ...

Cytoplasm is the fluid that fills up the cells. Its function is to support and suspend organelles and cellular molecules. Other functions of the cytoplasm include Maintain the shape of a cellCell movementMaterial exchange

Since the earth makes one complete revolution of 360° in 24 hours.Earth rotates 360 ° in 24 hr.Then in 1 hr =360°/24=15°1 hr=15°Also, 1 hr = 60 min.15°= 60min.1° = 60/15So, 1°= 4min. As you must know that Earth rotates from west to east, so every 15° we go eastwards ... Read More

To do: Rationalize the followingSolution: $\frac{1}{\sqrt{7} -\sqrt{6}}$Multiply by $\sqrt{7} +\sqrt{6}$ on numerator and denominator =$\frac{1}{\sqrt{7} -\sqrt{6}} \times \frac{\sqrt{7} +\sqrt{6}}{\sqrt{7} +\sqrt{6}}$=$\frac{\sqrt{7} +\sqrt{6}}{\sqrt{7}^{2} -\sqrt{6}^{2}}$=$\frac{\sqrt{7} +\sqrt{6}}{7-6}$=$\frac{\sqrt{7} +\sqrt{6}}{1}$=$\sqrt{7} +\sqrt{6}$Therefore on rationalizing $\frac{1}{\sqrt{7} -\sqrt{6}}$ we get $\sqrt{7}+\sqrt{6}$Read More
