Select the total number of false statement from the following (i) The globular head is an active ATPase enzyme and has binding sites for ATP and active sites for Myosin. (ii) Each Myosin (think) filament is also a polymerized protine. (iii) Many monomeric proteins celled Meromyosins canstitute one thick filament. (iv) Each meromyosin has two important parts, a globular head with a short arm and a til, the former being Called the heavy meromyosin (HMA) and the latter, the light meromysin (LMN). (v) The HMM component, i.e., the head and short arm projects outwards at regular distance and angle from each other from the surface of a polymerized myosis filament and is known as cross arm

Most of the polyatomic molecules except a few such as CO_(2) and CS_(2) are linear or angular with a bond angle generally somewhat greater than 90^(@) A bond angle is defined as the angle between the direction of two covalent bonds Since the atoms in molecules are in constant motion with respect to each other they are not expected to have a fixed value of bond angle Repulsion between non-bonded atoms alone does not provide an adequate explanation Hybridisation of bonding orbitals an adequate explanation Hybridisation of bonding orbitals also plays a very important role in detrmining the value of bond angle It has been observed that in hybridisation as the s-character of hybrid orbital increases the bond angle increases Which of the following hybridisation may have more than one type of bond angle ? .
