• B. Acts as he does because he expects that his behavior will yield positive results
• C. Uses visioning as the core of his leadership
• D. Matches his leadership style to the situation at hand.

2. Endotoxins are toxic substances released by:

• A. Viruses
• B. Bacteria (gram-positive)
• C. Bacteria (gram-negative)
• D. Parasites

Correct answer: C

Rationale: Rationale: Endotoxins are toxic substances that are part of the outer membrane of the cell wall of gram-negative bacteria. These toxins are released when the bacteria are destroyed or during bacterial growth. Endotoxins can cause a variety of harmful effects in the host, including fever, inflammation, and septic shock. Viruses do not produce endotoxins, and gram-positive bacteria produce exotoxins rather than endotoxins. Parasites are not typically associated with the production of endotoxins.

3. Which organelle is responsible for controlling the activities of the cell?

• A. Golgi apparatus
• B. Mitochondria
• C. Nucleus
• D. Ribosomes

Correct answer: C

Rationale: Rationale: The nucleus is the organelle responsible for controlling the activities of the cell. It contains the cell's genetic material (DNA) and serves as the command center of the cell, regulating gene expression and directing cellular activities. The nucleus plays a crucial role in cell growth, metabolism, and reproduction. The Golgi apparatus is involved in processing and packaging proteins, the mitochondria are responsible for producing energy in the form of ATP, and ribosomes are involved in protein synthesis. However, none of these organelles have the primary function of controlling the activities of the cell like the nucleus does.

4. You test a new fertilizer on two groups of plants, one with fertilizer and one without. Both groups grow at the same rate. What is the most likely explanation?

• A. The fertilizer has no effect on plant growth.
• B. The control group accidentally received some fertilizer too.
• C. Both groups received other nutrients from the soil, negating the fertilizer's effect.
• D. The test period was too short to observe any difference.

Correct answer: C

Rationale: A true control group should be identical to the test group except for the variable being tested. If both groups grew the same despite the fertilizer, it suggests external factors like soil nutrients masked any potential fertilizer effect.

• A. Unquestioning belief in established theories and models.
• B. Dogmatically adhering to the opinions of prominent scientists.
• C. Maintaining an open mind and willingness to consider new evidence.

Correct answer: C

Rationale: Science is a dynamic process built on continual questioning and refining of understanding. Openness to new evidence and revision of existing theories is crucial for scientific progress.
