B because in the first statement,if the grass population will decrease,rabbit population will also decrease as the rabbit exclusively feeds on the grass population and wolf exclusively feeds on the rabbit population.In the second statement,if the tiger population will increase,the rabbit population will decrease as the tiger exclusively feeds on the rabbit population and wolf exclusively feeds on the rabbit population.In the third statement,if the deer population will decrease,the wolf population will decrease as wolf feeds on the deer population.In the fourth statement,if the rabbit population will increase,the wolf population will also increase as wolf feeds on the rabbit population.

The correct answer is D because if you draw the axis and the equator, it will make a sign like a tilted x and the option that most relates to the shape we've received is option D(Master Answer)

Ans 4:

Class : Class 5
Answer should be D because equator is not slanting but if we mix equator and axis of the earth it will be criss crossed.

Ans 5:

Class : Class 9

Ans 6:

Class : Class 6
Awnswer is D

Ans 7:

Class : Class 5
The earth is tilted on its axis and the equator divides the earth into northern hemisphere and Southern Hemisphere. So, if we just imagine to remove the planet and just leave the axis and equator, we will get an X. To visualise take a piece of paper and rool it into a ball and draw a in the middle. Then tilt it a bit and you will get a model of the earth. Then it forms a X. So the answer is D.

Ans 8:

Class : Class 8
A as D shows criss crossed lines and equator isn't like that

Dear friends, see the question and the options clearly.As they have said in the question, the experiment is on how overcrowding affects plant growth.For that, the conditions in which the plant(s) are growing should be the same. That means that the amount of sunlight, amount of water, amount of soil and condition of soil should be the same, whereas the number of plants growing in one pot, should not..As we are assured in the question, they are already giving the same amounts of sunlight and water to the plants.We only have to see that the amount and condition of soil is the same, and that, my friends, is only in option 'C'.So, that i.e option 'C', is the correct answer.

Ans 27:

Class : Class 8
c is right

Ans 28:

Class : Class 7
ahana bag, in option d the soil in more plants is less and in option c the soil in both the pots are same. Just wanted to tell that you might be blind!!
