The correct answer is A.
Count the number of total balls = 21
Count the number of crossed balls = 6
So, the subtraction sentence will be 21 - 6.
Now make the subtraction sentences for all options:
(A) 2 tens 1 one - 6 ones = 21 - 6
(B) 2 tens 2 ones - 6 ones = 22 - 6
(C) 2 tens - 6 ones = 20 - 6
(D) 2 tens 3 tens - 6 ones = 23 - 6

but in some plants ther is no flower then also they can reproduce in a different manner

WE HAVE READ THAT THEY CAN GROW WITHOUT FLOWERSIF THEY HAVE NOT FLOWERS THEY GROW IN A DIFFERENT MANNERVERY STUPID OF SOFSO MANY ERRORSWHAT EVER CORRECT OPTION IS D
Ans 7:
Class : Class 4
I think it is seed only because if the other parts will no be there than how the previous plant will grow
Ans 9:
Class : Class 6
the answer is d as many plants don't have flowers but still reproduce. Without the leaves, the plants can't make food.
Ans 10:
Class : Class 5
Deepayan and Sumit are right..of course it is d, if there are no leaves the plant will die, how is it going to reproduce then??
Ans 13:
Class : Class 5
c) WHY? Here it goes:How will it reproduce without flowers?Ideally? Leaves? Does cactus have leaves? Nope! It has leaves -2 - spines...
Ans 14:
Class : Class 9
some plants can grow by vegetative reproduction which is not by flowers. Like carrots, Carrots does not have any flowers. I think the answer is D because if there are no leaves then who will make the food for the survival of the plant.

The correct answer is C
Flower changes into fruits and fruit bears seeds. Seeds give rise to new plants when sown into soil.

In papaya plant, flower changes into fruit and fruit bears seeds. Seeds give rise to new plants when sown into the soil.
Ans 18:
Class : Class 5
Think the correct ans'rs C Cause a flower changes into a fruit in the fruit then bears seads which give rise to new plants on being down in soil. That's what I think don't know if it is right!!!
Ans 20:
Class : Class 6
It is not c because new plants can rise by vegetative reproduction which are not by seeds.It is by roots, stem or leaves. what, in case of byrophyllum plant.

ACCORDING TO ME THE CORRECT ANSWER IS B , FIRST WE HAVE TO UNDERSTAND THE PICTURE AND THEN ANSWER
Ans 4:
Class : Class 6
Sorry for giving the wrong information. At the beginning even I thought the answer was B.If you click the solution button, it says that since the copper rod has the least amount of wax on it, it is the better conductor as all the other wax on it has melted and fell down. That is why the answer is A not B
Ans 7:
Class : Class 7
The answer is 'a' because the rods are fully coated with wax, those rods which have less wax are good conductors because the wax melted and fell from it.
Ans 12:
Class : Class 6
it cannot be as you have said because the wax is dripping from the glass rod whereas on the copper rod, it is as it was first placed. And they will not give us a diagram if they are going to ask something not related to it.So, the answer must be B and not A.
Ans 13:
Class : Class 8
why is everyone talking about wax and copper it is a question about statements and conductivity like bruh what
Ans 16:
Class : Class 3
the wax has been applied all over the rod. copper has the least amount of wax on it. So it is the best conductor of heat whereas the glass rod has the most amount of wax thus it is the weakest conductor of heat.Thus,the option "A" is the correct answer

The correct answer is D.
In a transverse wave the direction of the movement of the particle is perpendicular to direction of motion of the wave.
So, over here, when we move the end Q from left and right , it will produce a transverse wave,. You can check it by observing it from the top.
Ans 3:
Class : Class 8
In my opinion, the answer should be both option (C) and option (D). Transverse waves are waves in which the motion of particles are perpendicular to the motion of the wave (for example, light). Moving the slinky at an angle of 45 degrees to the table would create a wave, just not a perpendicular one, and thus not a transverse wave. This excludes option (A). Option (B) is also excluded, as it creates a longitudinal wave (motion of the particles is parallel to the motion of the wave). Option (C) involves the wave being moved up and down (assumed to be at right angles, since it is not mentioned). The slinky thus also moves up and down, and creates a transversal wave (as the motion of the wave is from Q to P, and the motion of the parts of the slinky is perpendicular to line QP). Option (C) is thus correct. Option (D) involves the wave being moved left to right (assumed to be at right angles, since it is not mentioned). This also created a transverse wave (as the motion of the parts of the slinky is perpendicular to the motion of the wave from Q to P). Option (D) is thus, also correct. Since we live in a three dimensional world, and it is not mentioned in the question that the experiment is performed in a 2 dimensional world, we can assume that the experiment is done in a 3D world. Due to the presence of length, breadth and height, the slinky can be moved in two ways perpendicular to line QP (i.e. the slinky). Given that both ways this can be done are mentioned in the question, both options must be correct. Therefore, I opine that the correct answer is both option (C) and option (D).
Ans 4:
Class : Class 8
Won't moving the slinky up and down produce the same result? You can check b observing from the side.
Ans 9: (Master Answer)
Class : Class 1
The correct answer is D
In transverse wave, vibration of a wave is perpendicular to its direction of propagation of wave.

The correct answer is A.
Sugar syrup is neutral and hence the colour of blue litmus and red litmus remains unchanged. Tamarind juice is acidic, so blue litmus turns red but red litmus does not change its colour. Lime water and soap solution are basic in nature which turn red litmus blue whereas blue litmus remains unchanged.

at 4 degree celsius water starts expanding and 'x' shows the same the room temperature might have been near or equal to the freezing point of water(eg room temperature of regions like arctic and antarctic)
Ans 3:
Class : Class 7
Three states - gas , liquid & solid
When hot water temp is going down it will be ultimate become solid ie ice
But before becoming ice temp will stagnant for some time where in both states liquid & solid co-exist==> some part of liquid is in ice form.
X is the same state where in solid and liquid will co-exist. Hence option 4 is correct(solidification& evaporation)
Note: Could not attach gif .It would have made it more clear.
Ans 6:
Class : Class 7
I think B is the correct answer because there is no solidification taking place or else the water would have turned into ice. plus no solidification can take place when water is at room temperature.
Ans 8:
Class : Class 10
i think there is no option correct in this ques. no evaporation and boiling is taking place as it is cooling down towards the room temperature. also no condensation is taking place as in the ques it is written a HOT liquid is being transferred to a beaker. as well as solidification may also not take place because room temp is above 0 degree centigrate. SOF PLEASE SEE TO IT THAT THIS TYPE OF WRONGG QUESTIONS AND SOLUTIONS ARE NOT POSTED.
Ans 14:
Class : Class 8
It is cooling towards room temperature so it does not solidify since the freezing point is below room temperature.
Ans 19:
Class : Class 7
There is no proper solution for this question which will make it more confusing as everyone will have different opinions in this question.
