The correct Answer is:
**Step-by-Step Text Solution:** 1. **Understanding the Question**: The question asks about cell-like structures created by scientists under specific conditions that lack true cellular organization. 2. **Identifying the Context**: Scientists have been able to simulate conditions similar to those of primitive Earth, which has led to the formation of these structures. 3. **Defining the Structures**: The structures formed are not considered true cells because they do not possess the complete organization and functionality of a living cell. 4. **Naming the Structures**: These cell-like structures are referred to as "Poserweitz." This term is used to describe these primitive, cell-like entities that scientists have created in laboratory settings. 5. **Selecting the Correct Answer**: From the given options—eubions, protists, poserweitz, and microbes—the correct answer is "Poserweitz." **Final Answer**: The cell-like structures created under certain conditions by scientists, which lack true organization, are called Poserweitz. ---

Cell voltages and half-cell potentials are often compeared under standard conditions called the standard state at a specified temperature (298K). The standard state requires all reagents to be pure with all gases at unit fugacity, all ions at unit activity and all electrical connections between half-cells to be made with platinum. Suppose following are half cell reaction, with respective emf (s) are -0.25 V and -0.3V. Cell reaction I underset("1 atm")(Pt(H_(2))|HCl) Cell reaction II underset("1 atm")(Pt(H_(2))|H_(2)SO_(4)) pH value of cell reaction I is

When any two sides and one of the opposite acute angle are given, under certain additional conditions two triangles are possible. The case when two triangles are possible is called the ambiguous case. In fact when any two sides and the angle opposite to one of them are given either no triangle is posible or only one triangle is possible or two triangles are possible. In the ambiguous case, let a,b and angle A are given and c_(1), c_(2) are two values of the third side c. On the basis of above information, answer the following questions Two different triangles are possible when
