We categorized or differentiate vast things into different parts for the ease of studying them well.Plants have also so many things to study, therefore we differentiate the different parts of the plants to distinguish between their functions.

To do: To find the probability of drawing a black queen a black card and a black face cardSolution:Total number of card =52Probability of drawing a black queen No. of black queens = 2. So, Probability of black queen = $\frac{2}{52} = \frac{1}{26}$. Probability of drawing a black cardNo. of ... Read More

In 1665, the English scientist 'Robert Hooke' observed a cork slice through a primitive compound microscope and discovered a honeycomb structure. It was appearing like many tiny pores and he named them "cells". The word "cell" was taken from the Latin word Cella, which means 'a small room ... Read More

Chemical Expansion- Substances expand (increase in size) when they get warmer, and they contract (decrease in size) when they get cooler. This property can be useful. For example, Thermometers work because the liquid inside them expands and rises up the tube when it gets hotter.

Buoyant forceImagine a rubber ball being dropped in a tub full of water. We can observe that the larger portion of the ball stays above the water surface, and the smaller portion of the ball remains submerged in the water. When we try to submerge the ball completely, we would ... Read More

Given:  $4\frac{1}{6}\times\frac{2}{5}\div\frac{1}{3}$ To do: Solve the expression Solution:  Convert the mixed fraction to improper fraction:So, $4\frac{1}{6}=\frac{25}{6}$   Now, $\frac{25}{6}\times\frac{2}{5}\div\frac{1}{3}$ $\frac{25}{6}\times\frac{2}{5}\times3$ $\frac{25\times2\times3}{6\times5}$ $\frac{5\times2}{2}$                           [$5\times5=25 and 3\times2=6$] Therefore the solution is $5$ 416 = 4×6 + 16 = 256. 4\frac{1}{6} \ =\ \frac{4\times 6\ +\ ...
