### Reasons for Endospore Heat Resistance

**Question:**
Which are reasons why endospores can resist death by moist heat? (Select the 2 correct answers)

**Options:**
1. They have a low internal concentration of water.
2. They have a high concentration of water.
3. They have heat stable proteins in the endospore.
4. They are not living and therefore do not die.

**Explanation:**
Endospores are highly durable, non-reproductive structures formed by some bacteria. They allow the bacteria to survive extreme environmental conditions, including high temperatures, lack of nutrients, and chemical exposure. This question tests the understanding of the key factors contributing to the heat resistance of endospores.

Understanding the correct answers requires knowledge of the structural and biochemical properties of endospores that enable their survival under extreme conditions.
