• Amoeba is a microscopic single-celled organism found in pond water which has a cell membrane, a round, dense nucleus and many bubble like vacuoles.
• The shape of amoeba is variable.
• It has tiny finger like projections called pseudopodia or false feet for movement and capture of food.
• It eats tiny organisms by spreading out its pseudopodia around its food particle and then engulfing it.
• The food gets trapped inside food vacuole, into which digestive juices are secreted and convert them into simpler substances.
• The digested food is then absorbed which is required for growth, maintenance and multiplication.
• The undigested food is expelled out by vacuole.

-13 + (-69) + 57 - (-89) - [53 + (-49) ]

= -13 + (-69) + 57 - (-89) - 53 -49)

= -13 - 69 + 57 + 89 - 53 - 49

= - [13 + 69 + 53 + 49]+ 57 + 89

= - 184 + 146

=- 38
