The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Concept**: The question refers to the Scala naturae, also known as the "ladder of nature," which is a classification system that organizes living organisms in a hierarchical manner. 2. **Identifying the Originator**: The Scala naturae is attributed to Aristotle, who was a Greek philosopher and is often considered the father of biology. He was the first to classify living organisms based on their complexity and characteristics. 3. **Explaining Hierarchical Classification**: Aristotle's classification system arranged organisms from the simplest forms of life to the most complex. This hierarchy can be likened to a school structure, where there are different levels of authority and complexity. 4. **Reviewing the Options**: The options provided in the question are: - Heckel - Aristotle - Levenhoff - Coveyall 5. **Selecting the Correct Answer**: Based on the understanding that Aristotle was the first to propose a hierarchical classification of living organisms, the correct answer is **Aristotle**. **Final Answer**: The Scala naturae was first proposed by **Aristotle**. ---

India relishes a history of religious and culture traditions which emphasised the protection of nature. In many cultures, tracts of forest were set aside, all the trees and wildlife within were venerated and given total protection. Such areas are refferred to as (a) hotspots (b) ethical groves (c) sacred groves (d) protected areas

In a potato race, a bucket is placed at the starting point, which is 5 m from the first potato, and the other potatoes are placed 3 m apart in a straight line. There are ten potatoes in the line (see Figure). A competitor starts from the bucket, picks up the nearest potato, runs back with it, drops it in the bucket, runs back to pick up the next potato, runs to the bucket to drop it in, and she continues in the same way until all the potatoes are in the bucket. What is the total distance the competitor has to run? [Hint : To pick up the first potato and the second potato, the total distance (in metres) rim by a competitor is 2 x 5 + 2 x (5 + 3)]

Two ideal Carnot engines operate in cascade (all heat given up by one engine is used by the other engine to produce work) between temperatures, T_(1) and T_(2) . The temperature of the hot reservoir of the first engine is T_(1) and the temperature of the cold reservoir of the second engine is T_(2) . T is temperature of the sink of first engine which is also the source for the second engine. How is T related to T_(1) and T_(2) , if both the engines perform equal amount of work?

There exists a uniform magnetic field vec(B) = +B_(0) hat(k) " for " x gt 0 and vec(B) = 0 for all x lt 0 . A charged particle placed at (0, -a,0) is given an initial velocity vec(v) = v_(0) hat(i) . What is the magnitude and nature of charge on the particle such that it crosses through the origin ? Strategy: When the charge is projected perpendicular to a uniform magnetic field, it follows a circular path. In this case, the force acting on it will be directed either towards +y-axis. or y-axis. It is given that it crosses point O. Thus, the force at (0, -a, 0) must be towards y-axis

The system shown in the figure is in equilibrium, where A and B are isomeric liquids and form an ideal solution at TK . Standard vapour pressures of A and B are P_(A)^(0) and P_(B)^(0) , respectively, at TK . We collect the vapour of A and B in two containers of volume V , first container is maintained at 2 T K and second container is maintained at 3T//2 . At the temperature greater than T K , both A and B exist in only gaseous form. We assume than collected gases behave ideally at 2 T K and there may take place an isomerisation reaction in which A gets converted into B by first-order kinetics reaction given as: Aoverset(k)rarrB , where k is a rate constant. In container ( II ) at the given temperature 3T//2 , A and B are ideal in nature and non reacting in nature. A small pin hole is made into container. We can determine the initial rate of effusion of both gases in vacuum by the expression r=K.(P)/(sqrt(M_(0))) where P= pressure differences between system and surrounding K= positive constant M_(0)= molecular weight of the gas If vapours are collected in a container of volume 8.21 L maintained at 3 T//2K , where T=50 K , then the ratio of initial rate of effusion of gases A and B is given as

Assume ideal gas behaviour for all the gases considered and neglect vibrational degrees of freedom. Separate equimolar sample. Separate equimolar samples of Ne, O_(2) , CO_(2) and SO_(2) were subjected to a two process as mentioned. Initially all are at same state of temperature and pressue. Step I rarr All undergo reversible adiabatic expansion to attain same final volume, which is double the original volume thereby causing the decreases in their temperature. Step II rarr After step I all are given appropriate amount of heat isochorically to restore the original temperature. Mark the correct option(s) :

In a potato race, a bucket is placed at the starting point, which is 7 meter from the first potato. The other potatoes are placed 4 m a part in a straight line from the first one. There are n potatoes in the line. Each competitor starts from the bucket, picks up the nearest potato, runs back with it, drops in the bucket, runs back to pick up the next potato, runs to the bucket and drops it and this process continues till all the potatoes are picked up and dropped in the bucket. Each competitor ran a total of 150 m. The number of potatoes is. "____________"
