Answer Analysis

A lack of vitamin A can significantly impact various physiological processes. Here is a detailed explanation of each option:

1. Nerve Transmission: While vitamin A is not primarily associated with nerve transmission, it plays a role in the overall health of neurons. However, this is not the most direct effect of vitamin A deficiency.

2. Immune Function: Vitamin A is crucial for maintaining a healthy immune system. It supports the function of various immune cells and helps in the production of antibodies. Thus, a deficiency can lead to compromised immune responses.

3. Visual Function: Vitamin A is well-known for its essential role in vision, particularly in the formation of rhodopsin, a protein in the retina that is critical for low-light (night) vision. A deficiency can lead to visual impairments and even night blindness.

4. Growth and Development: Vitamin A is important for growth and development, especially in children. It is necessary for cell growth and differentiation. Lack of vitamin A can hinder proper development and growth in children.

Final Selection

Therefore, the correct selections are:

• Immune function
• Visual function
• Growth and development

In summary, a lack of vitamin A specifically affects immune function, visual function, and growth and development, while its effect on nerve transmission is minimal.
