There are certain enzymes which help in the passage of solutes by opening or closing of channels present in the membrane which allows the entry of solutes inside the cell. At very low temperature and at very high temperature there is inactivation of enzymes as enzymes are proteins.

Roots are geotropic i.e they move towards the gravity. They are not phototropic which is charateristic of stem..

For physics read HCV and resnick halliday..For inorganic read JDlee, For organic read Arihant and Morrison and boydFor physical go for arihant.. In maths ML khanna, TMH, Rd sharma..Above all read NCERT books and use reference books for better understanding on topic..

Arihant Chemistry along with this, morrison n boyd..

Ya its enough but grasp all the concepts from it by using some reference books also..
|
|
|
|
|
It doesn't matter how many students are giving the test but u should give it for YOUR's best prepartion..
|
|
|
|
|
Start preparing for chemistry as soon as possible.. U have enough time to prepare but be rigid in ur preparation.. Along with chemistry try to focus and revise other subjects as well.All the BEST!

Whereever u go to study, u have to put ur own efforts inspite of the fact that many students get their selection from these institutes.. Although Kota is far better.. there coachings are exclusively for IIT and their material is good for IIT..
|
|
|
|
|
It depends on ur inclination,wether u want to get selected in IIT or want to continue in same college.. manage ur study according to it.. Plan a tym table and follow it..If u r very much desperate and confident to get select then, focus more on IIT..

rate of work i.e power=work done/timeas we know work done=Force*displacementand Force=pressure*areaso, POWER=PRESSURE*AREA*DISPLACEMENT/TimeNow area*displacement=volumeso, formula becomes Power=Pressure*volume/time..and time=1/frequency..put the values in it and get the answer

NO2 <--->N2O4.. Consider this reaction..AT the room temperature it is impossible to obtain a equilibrium at room teperature but in a sealed container this reaction can achieve equilibrium..Therefore the ratio of concentration of these two will be NO2/N2O4 which will be constant called Keq(euilibrium constant).. thus law of mass of action states that at a given temperature, for the system in equilibrium, the ratio of concentration of reactants and products will be constant as the system in equilibrium..

For maths use RD sharma. for physics use HCV and for chemistry use Arihant books..

Studying long hrs can't make u eligible for IIT but study with concentration helps u in getting ur seat in IIT.. i think studying 5-6 hrs is sufficient but these hrs should only be devoted to study.. and study with full concentration..Whatever u have planned for urself today should be completed..

Dear, u require at least 60% as a eligibility criteria for IIT....

- He wii suffer from Marasmus as marasmus is a disease of defficiency in both protein and carbohydrates..
- Rickets due to vitamin D defficiency..
- Kwashiorkar due to defficiency in protein..
- pellagra due defficiency of niacin.

Due to LH there occurs ovulation..Actually progesterone inhibit LH secretion and estrogen inhibit FSH secretion..When the level of these hormones are low then there is LH surge responsible for ovulation..when the ovum didn't get fertilize, there is shedding of endometrium as progesterone is now less which is very important in maintaing the endometrium for implantation of foetus.High levels of progesterone inhibit secretion of Gonadotropins(FSH and LH) by feed back inhibition..

Just practice a lot and whatever u r not able to learn , go for the reference books from which u can easily remember the facts and easy to understand..Whenever y get stuck in numerical problems, read the theory again for that topic.. Finally don't compare urself with anybody as this creates a limit in ur performance.. U will not think high for urself..
|
|
|
|
|
join correspondence course of BT or FIITJEE for 9th standard.. It will help u..Develop redaing habit in urself and also increase ur reading speed along with ur catching power..
