(i) Temperature, pH and concentration of substrate can influence enzyme activity ? (ii) ES complex is short lived and dissociates into products (P) (iii) In exothermic reaction, the energy level of "P" is lower than "S" substrate (iv) Cofactors play a crucial role in the catalytic activity of the enzyme. Which of the above statements are correct ?

Inhibition of succinic dehydrogenase by malonate which closely resembles the substrate____in structure.

A string 25cm long and having a mass of 2.5 gm is under tension. A pipe closed at one end is 40cm long. When the string is set vibrating in its first overtone and the air in the pipe in its fundamental frequency, 8 beats per second are heard. It is observed that decreasing the tension in the string decreases beat frequency. If the speed of sound in air is 320m//s , find the tension in the string.

In a leaf, when its lamina is entire or when incised, the incisions do not touch the midrib then this type of leaf is known as
