Option A says involuntary muscles are controlled by brain. It is correct as medulla controls all our involuntary actions. Option B and C are correct as the cardiac muscles are also called as smooth muscles, so statement d is incorrect as the muscles present in our arms and legs are called skeletal or voluntary muscles

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

Ans 3:

spj2011 from DB, Chennai
Class : Class 4
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 4:

Twisha Arora from MRIS- 21C, Faridabad
Class : Class 4
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)

Some children wanted to find out how overcrowding can affect plant growth. They took four pairs of plants, A, B, C and D, as shown here and kept them at the same location. Each pot is given the same amount of water each day. Which pair of plants will give the correct result of their experiment?

A
B
C
D


in option C the amount of soil is the same but in the first pot there are less flowers and in the other pot there are more flowers and they both havegood soil

Ans 1:

Mohhika Sharma from Delhi Public School Greater Noida, Greater Noida
Class : Class 4
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.
