Statement | : oxytocin from the maternal pituitary which induces mild uterine contractions . Statement || : the signals for parturition originate from the fully devloped foetus and placenta which causes stronger uterine contractions

Which of the following is correct for free expansion of ideal gas under isothermal condition :

A sample of 3 mol of an ideal gas at 300K and 2 atm is compressed reversibly and adiabatically until the temperature reaches 350K given molar heat capacity at constant volume is 30 J/K mol, then find work?

An acidic buffer is prepared by mixing : (NEET 2023 (manipur) )

The equivalent weight of the salt KHC2O4.H2C2O4.4H2O Used as reducing agent is :(NEET(UG)2021(paper-2)

Assuming complete ionization, same moles of which of the following compounds will require the least amount of acidified KMnO4 for complete oxidation? (RE-AIPMT 2015)

In which stage of embryonic development embryonic cells form the germinal layers by the movement?

Assertion: acceleration of the particle in uniform circular motion remains constant. Reason: velocity of the particle doesn't change in circular motion.

Which component is mainly responsible for penetration of corona radiata?

If the length of a DNA molecule is 136 nm then what will be the number of base pair in it?

The radius of DNA double helix is ;

Assertion: mass, volume and pressure are extensive properties. Reason: extensive properties depends on amount of substances.

Flow of energy declines from low to higher trophic level in ecosystem, is mainly explained by;

Conservation of biodiversity for pollination of plants, comes under :

Assertion: Nitrous acid can act as an oxidising agent as well as reducing agent Reason: oxidation no. of all nitrogen remains same in all the compounds

Assertion: in a redox reaction the oxidation no. of oxidant decreases while that of reductant increases Reason: oxidant gains electron while reductant losses electron

Assertion: oxidation no. of carbon in all it's compound is +4. Reason: An element has a fixed oxidation state.

Assertion: in NH4NO3 the oxidation no. of 2 N atoms is not equal. Reason: 1 N Atom is present in amonium ion while the other is present in nitrate ion.

Assertion: Oxidation no. of carbon in HCN is +4 Reason: C always show oxidation no. of +4
