1. He emphasizes to the team that they need to put their efforts together towards the attainment

A. Span of control
B. Unity of direction
C. Unity of command
D. Command responsibility

Correct answer: B

Rationale: The correct answer is B: Unity of direction. Unity of direction is a principle of management which states that all activities within an organization should be directed towards the same objectives. In this scenario, the leader is stressing the importance of aligning the team's efforts towards a common goal or objective. This ensures that everyone is working towards a shared purpose, avoiding conflicting or contradictory actions. Span of control refers to the number of subordinates a manager can effectively supervise. Unity of command relates to the principle that employees should receive orders from only one supervisor to avoid confusion and conflict. Command responsibility is a term often used in the context of accountability for actions taken under one's command. Therefore, the most appropriate concept in this context is Unity of direction.

4. 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.

5. Which organelle is responsible for the final stages of protein modification and packaging for secretion in animal cells?

A. Rough endoplasmic reticulum (RER)
B. Smooth endoplasmic reticulum (SER)
C. Ribosomes
D. Golgi apparatus

Correct answer: D

Rationale: The Golgi apparatus is responsible for the final stages of protein modification and packaging for secretion in animal cells. After proteins are synthesized in the rough endoplasmic reticulum (RER) and modified in the Golgi apparatus, they are packaged into vesicles for secretion. The smooth endoplasmic reticulum (SER) is involved in lipid and carbohydrate metabolism, while ribosomes are responsible for protein synthesis on the RER. Therefore, the Golgi apparatus is the correct organelle for the final processing and packaging of proteins for secretion in animal cells.

6. What is the scientific term for a broken bone?

A. Osteoporosis
B. Fracture
C. Sprain
D. Dislocation

Correct answer: B

Rationale: The correct answer is B: 'Fracture.' A fracture is the scientific term used to describe a broken bone. Osteoporosis (A) is a condition where bones become weak and brittle, increasing the risk of fractures. A sprain (C) is an injury to a ligament, not a bone. A dislocation (D) occurs when the bones in a joint are forced out of their normal position, but it is not the term for a broken bone.
