Your DS answer which is 3,is correct.Option 4 is not the answer as the snails may have eaten up the plant.You can say option 4 when they show the observation in each day that the snails is eating the plant.I would say not possible to tell.
Option 1;Double confirm it is wrong.Only plants,not animals,need light to survive.
Option 2 is wrong as we do not know whether snails eat plants.That also comes under not possible to tell.
Thus,answer 3 is correct.

Yes.Onion does reproduce by buds.But i think they should put 'reproduce by buds instead of the'reproduction in seeds'.But this does not affect the answer.Your understanding is correct.

Answer key is wrong.Answer should be 1.Look at cell d closely.You would observe it also has a regular shape.Cell B is a plant cell taken from the aquatic plants.Cell a has the same features as cell d.Therefore,all options except option c,in which the cell is irregular,is considered the answer. -
Thx you Charsen!

I am not going to tell all the answers.Use the strategy that i taught you.Find the topic and the concept of the question.For the circuit question,trace the electricity path of each option.
For each question,you tell me the topic and the concept.Once i correct it,you could find the answer.
Cheers
