Answer: D. It is useful only when an antigen invades a body for the second time.

Explanation: Adaptive immunity, also referred to as acquired immunity, comes into play when innate immunity is breached. Adaptive immunity isn't very helpful in protecting your body when specific bacteria, virus, or any other microorganism enter your body for the first time. Its components function by learning the pathogen and then developing immunity against it. **(The adaptive immune system develops antibodies against the invaded pathogen after the first entry)**. If the same or similar pathogen enters the bloodstream again, your body will have a full-blown defense ready to destroy the pathogen. The mechanism of adaptive immunity is essentially concerned with your body's capability to recognize and destroy substances which it interprets as foreign and harmful... PF.

Why is photosynthesis so important to living organisms?
konstantin123 [22]

Answer:

All living organisms need energy to stay alive, but only producers can directly convert energy into food.

Explanation:

The process of photosynthesis is very important because all living organisms need energy to stay alive, but only producers can directly convert energy into food.

Photosynthesis is the process whereby green plants manufacture their food in the presence of carbon dioxide and water.

  • They take light energy from the sun and produce food materials.
  • The light energy is converted to chemical energy which are stored in carbon chains as glucose.
  • The  chemical energy is then used by other living organisms for their own nourishment.

Which immune component is deficient in a child who has a congenital immunodeficiency that impairs b lymphocyte function?
Artist 52 [7]

Neutrophils component is deficient in a child who has a congenital immunodeficiency that impairs <u>B lymphocyte</u> function.

Neutrophils- A specific kind of white blood cell that aids in the body's defense against infection and is crucial to the immune system. White blood cells are one of the initial immune cells to react when bacteria or viruses enter the body.

B Lymphocytes- By generating antibodies, B cells are essential for pathogen-specific immunity. Immunoglobulins attached to the surface of B lymphocytes allow them to identify soluble antigens, causing them to develop into plasma cells, which can secrete immunoglobulins and produce antibodies. Primary lymphoid tissues include lymphocytes.
