The correct Answer is:
To solve the question, we need to analyze the characteristics of the bacterium described and identify what structure it is likely able to form to withstand extreme conditions. ### Step-by-Step Solution: 1. **Understanding the Conditions**: The question states that the bacterium can withstand extreme heat, dryness, and toxic chemicals. These conditions are typically harsh and can be detrimental to most living organisms. 2. **Identifying Possible Structures**: The options provided are: - Thick peptidoglycan wall - Endospore - Endotoxin - Endogenous burn 3. **Evaluating Each Option**: - **Thick Peptidoglycan Wall**: While a thick peptidoglycan wall provides structural support and protection against some environmental stresses, it does not specifically confer the ability to withstand extreme heat and dryness. - **Endospore**: Endospores are highly resistant structures formed by certain bacteria in response to unfavorable conditions. They allow bacteria to survive extreme heat, desiccation, and chemical exposure. This is a strong contender. - **Endotoxin**: Endotoxins are components of the bacterial cell wall that can cause immune responses in hosts but do not provide protection against extreme environmental conditions. - **Endogenous Burn**: This term does not relate to bacterial structures and is not relevant in this context. 4. **Conclusion**: Given that endospores are specifically designed to help bacteria survive extreme conditions, the correct answer is **endospore**. ### Final Answer: The bacterium is probably able to form **endospore**. ---

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 :
