Plant cells are eukaryotic cells (like the animal cells) meaning they have a membrane-bound nucleus and organelles present in green plants.Plant cells have cell walls, surrounding the cell membrane and composed of cellulose, hemicelluloses, and pectinPlant cell walls are composed of cellulose, which keeps them apart from other organisms with ...

Mode:Mode is the observation in a data set that occurs most frequently or the value that occurs maximum number of times.Example: Find the mode of the data set {5, 6, 10, 10, 10}.Solution: In this data set there is one 5, one 6 and three 10s. The mode of this ... Read More

The main parts of an electric motor include a voltage source, a shaft, an electromagnet, and at least one additional magnet. The shaft of the motor turns other parts of the device.Therefore in motors electromagnets are used.

Yes, electromagnets are used in motors. A motor also contains normal magnets(permanent magnets). The poles of the normal magnet interact with the poles of the electromagnet, causing the motor to turn.  

The act or process through which something becomes different is called a change.It can be a Physical or Chemical change, a Temporary or Permanent Change, a Reversible or Irreversible Change, A favourable or Unfavourable Change.

Both creepers and climbers are weak-stemmed plants and, hence cannot grow erect without support.  The difference between these two is, creepers spread horizontally along with the soil, whereas climbers take the support of an object for climbing. Climbers have a very thin, long, and weak stem that cannot stand erect ... Read More

(a) For X, atomic number is 17. So it is Chlorine. It is highly electronegative and it gains electrons.      For Y, atomic number is 12. So it is Magnesium. Magnesium will lose electrons  (b) Valency is the number of electrons an atom loses, gains or shares(c) The atom X has ... Read More

Given: The given ratio is 85:561To do: Simplify the equationSolution:$\frac{85}{561}$ $85 = 5 \times 17$$561 = 3 \times 11 \times 17$ So, $\frac{85}{561} = \frac{5 \times 17}{3 \times 11 \times 17} = \frac{5}{33}$

The stool is a piece of faeces.Faeces are body waste discharged from the intestine; called also stool, excrement, and excreta. The faeces are formed in the colon and pass down into the rectum by the process of peristalsis.In common term, potty or poop.

Given: 3a - 2(2a - 5) = 2 (a + 3) - 8To find: We have to find the value of a in 3a - 2(2a - 5) = 2 (a + 3) - 8.Solution: 3a - 2(2a - 5) = 2 (a + 3) - 8 ⇒ 3a - 4a + 10 = 2a + 6 - 8 ⇒ -1a + 10 = 2a - 2 ⇒ 2a + 1a = 10 + 2 ⇒ 3a = 12 ⇒ a = 12/3 ⇒ a = 4
