The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Auxins**: Auxins are a class of plant hormones that play a crucial role in the growth and development of plants. They are primarily produced at the tips of stems and roots. 2. **Types of Auxins**: The question mentions specific types of auxins: Indole-3-acetic acid (IAA), Indole-3-butyric acid (IBA), and Naphthalene acetic acid (NAA). These are simple auxins that can be applied artificially. 3. **Function of Auxins**: One of the key functions of auxins is to promote fruit development. When auxins are applied to unpollinated pistils, they can stimulate the development of fruits without the need for fertilization. 4. **Parthenocarpy**: The process of fruit formation without fertilization is known as parthenocarpy. The fruits produced in this manner are typically seedless. 5. **Conclusion**: Therefore, the artificial application of auxins like IAA, IBA, and NAA to unpollinated pistils results in the formation of seedless fruits, which are referred to as parthenocarpic fruits. ### Final Answer: The artificial application of auxins like IAA, IBA, and NAA to unpollinated pistils can form **seedless fruits (parthenocarpic fruits)**. ---

Limestone is a naturally occuring form of calcium carbonate. It is used as building materials and also for manufacture of other building materials such as portland cement. It is used for the production of quickline and slaked lime which have wide applications in chemical, metallugical and construction industry. The pure CaCO_(3) , called precipitated calcium carbonate, is used extensively as filler, providing bulk to materials such as paint, plastics, printing links and rubber. it is also used in toothpastes, cosmetics and antacids. Quicklime and slaked lime are the cheapest and the most widely used bases for neutralising unwanted acids. Lime is used to neutralise acidic soils. An important application of quicklime is in air pollution control for the removal of SO_(2) in electric power plants. slaked lime is used in the manufature of other alkalis and bleacing powder, in sugar refinig, in tanning hide and in water softening. The substance not likely to contain CaCO_(3) is

Silicones are synthetic polymers containing repeated R_2 SiO units . Since the empirical formula is that of a ketone (R_2 CO) , the name Silicone has been given to these materials . Silicone can be made into oils , rubbery elastomers and resins . They find a variety of applications because of their chemical inertness , water repelling nature, heat resistance and good electrical insulating property . Commerically silicon polymers are usually synthesised by the hudrolysis of R_2 SiCl_2 [R = Methyl (Me ) or phenyl ( phi)] . If we start with SiMeCl_3 as the starting material silicones formed is :

The small size and high charge of Al^(3+) ion gives it a high charge density which is responsible for its tendency to show (a) covalency in its compounds in the gaseous state (b) high hydration energy which stabilizes its compounds in solution, and (c) high lattice energy of its compounds in the solid state. Thus aluminium can forms both covalent and ionic bond. Like halides of boron, halides of aluminium do not show back bonding because of increase in size of aluminium. Actually aluminium atoms complete their octets by forming dimers. Thus chloride and bromide of aluminium exist as dimers, both in the vapour state and in polar-solvents like benzene while the corresponding boron halides exists as monomer. In boron trihalides the extent of back bonding decreases with increases with increase in size of halogens and thus lewis acid character increases. All BX_(3) are hydrolysed by water but BF_(3) shows a different behaviour. Which of the following statements about anhydrous aluminium chloride is correct ?

In one-dimensional kinematics, a particle can move strictly along a straight line. The description of motion of the particle can be done in two ways: (i) mathematical equation and (ii) graphs. The choice of a particular method for solving a problem often depends upon the type and nature of problem, for example the graphical method provides more physical insight One dimensional motion is categorised into 1. motion with constant velocity 2. motion with constant acceleration, and 3. accelerated and de-accelerated motion If you represent inotion (1) by the graph on position time and velocity-time coordinates, the graphs may look like as given below. One very interesting case comes up, when a particle is thrown at a certain angle from the horizontal, the particle travels in the medium along a curved path, known as parabola. - The trajectory of the parabola written in the mathematical equation is given by y=xtantheta-(1)/(2)(gx^(2))/((v_0costheta))^(2) Ineglect resistance of medium and its motion where Vs and are the initial velocity of the projectile and the projection angle at the point of projection measured with the + x axis. There are some applications which we have seen in our life, like in many game shows, the theory of the projectile is always used An air gun is aimed at an elevated target, which is released in a free fall by some mechanism as the bullet leaves the nozzle. Irrespective of falling speed of object, the bullet will always hit the target. QOut of the two methods, graphical method and mathematical equation, which gives you the better precision
